Description

平面开关模式有源矩阵型液晶显示器件及其制造方法 Plane switching mode active matrix liquid crystal display device and manufacturing method thereof

发明的技术领域本发明涉及液晶显示器件和它的制造方法,特别是涉及一种平面开关模式有源矩阵型液晶显示器件及其制造方法。 Technical Field of the Invention The present invention relates to a liquid crystal display device and its manufacturing method, particularly to an in-plane switching mode active matrix type liquid crystal display device and a manufacturing method.

发明背景液晶显示器件可以分成两大类型,其中之一是定向后的液晶分子的分子轴在垂直于基板的平面上旋转,以便显示某图像;另一种类型是定向后的液晶分子的分子轴在平行于基板的平面上旋转,以便显示某图像。 BACKGROUND OF THE INVENTION The liquid crystal display device can be divided into two types, one of which is the molecular axis of the liquid crystal molecules rotate on the plane of the substrate is oriented in the vertical, so as to display an image; Another type of the molecular axis orientation of the liquid crystal molecules in a plane parallel to the substrate is rotated so as to display an image.

前一类型中的标准模式是扭曲向列(TN)模式的液晶显示器件,后一种类型被称作平面开关(IPS)模式液晶显示器件。 The former type of the standard mode is a twisted liquid crystal display device (TN) mode nematic, the latter type is referred to as in-plane switching (IPS) mode liquid crystal display device.

因为观者只是从沿液晶分子的短轴延伸的方向观看,即使他/她移动视点,在IPS模式的液晶显示器件中,液晶分子如何排列并不取决视角,因此,IPS液晶显示器件可以为观者展现比TN模式的液晶显示器件宽的视角。 Because the viewer is only a minor axis viewed from a direction extending along the liquid crystal molecules, even if he / she moves the viewpoint, in the liquid crystal display device of IPS mode, the liquid crystal molecules does not depend on how the arrangement angle of view, therefore, IPS liquid crystal display device may be a concept who exhibit wider than the TN mode liquid crystal display device perspective.

因此现在IPS模式液晶显示器件要比TN模式器件更为普及。 Thus IPS mode liquid crystal display device is now more popular than the TN mode devices.

例如,日本待审专利公开号07-036058就提出了一个IPS模式液晶显示器件的实例。 For example, Japanese Unexamined Patent Publication No. 07-036058 proposed an example of a liquid crystal display device of IPS mode. 在此试图提供一种具有更高开孔率的IPS模式液晶显示器件,例如日本待审专利公开号11-119237、10-186407、9-236820和6-202127等。 In attempting to provide an IPS mode liquid crystal display device having a higher opening ratio, and the like for example, Japanese Unexamined Patent Publication No. 6-202127 and 11-119237,10-186407,9-236820.

日本待审专利公开号11-119237建议的IPS液晶显示器件的特点是,它们的驱动电极(相当于本发明中的像素电极)和对置电极(相当于本发明中的公共电极)在一个层面上形成,它不同于形成信号线的层面,并且其位置更接近液晶层。 Japanese Unexamined Patent Publication No. 11-119237 proposed IPS liquid crystal display device characteristic is that they drive electrodes (corresponding to the pixel electrode of the present invention) and the counter electrode (according to the present invention corresponds to the common electrode) at a level is formed, it is different from the level of the signal line is formed, and its position is closer to the liquid crystal layer. 这种结构可以保证对置电极受到由信号线和形成在开口端、并与信号线毗邻的对置电极之间的电压差产生的电场的影响很小,因此有可能将对置电极设置在更接近信号线对置电极的位置。 This structure ensures that the opposite electrode is subjected to electric voltage difference between the counter electrode and the signal line are formed at the open end, adjacent to the signal line and produces small, it is possible counter electrode disposed more close position signal wire counter electrode. 结果,有可能增加开口面积。 As a result, it is possible to increase the open area.

日本待审专利公开号11-119237进一步建议,驱动电极和对置电极可以由透明材料制成,例如ITO等。 Japanese Unexamined Patent Publication No. 11-119237 further recommended that the drive electrode and the counter electrode may be made of a transparent material such as ITO. 然而并没有披露对置电极与信号线重叠的问题。 However, the counter electrode does not disclose the problem of overlapping the signal line.

日本待审专利公开号11-119237进一步建议一种IPS模式的液晶显示器件,其中驱动电极和对置电极形成在形成信号线的层面之上的层面上,并且对置电极与信号线重叠。 Japanese Unexamined Patent Publication No. 11-119237 further recommended An IPS liquid crystal display device, wherein the drive electrode and the counter electrode is formed on a level above the level of the signal line, the counter electrode and overlapping the signal line. 这种结构可以保证驱动电极和对置电极很少受到从信号线泄露的电场的影响,光也不会从信号线和对置电极之间形成的缝隙中泄露。 This structure ensures that the driving electrode and the counter electrode is rarely influenced by the electric field leaking from the signal line, the slit light is not formed between the signal line and the counter electrode leaked.

然而它没有建议驱动电极和对置电极是透明电极,因为对置电极需要与信号线重叠,以便起到阻断缝隙露光的目的。 However, it does not suggest the driving electrode and the counter electrode is a transparent electrode, the counter electrode because the need to overlap the signal line, so as to serve the purpose of blocking light exposure slit.

在日本待审专利公开号10-186407披露的IPS模式液晶显示器件中,在形成公共电极的公共电极层和形成数据线的数据线层之间形成了一个电绝缘层,并且公共电极层的位置要比数据线层更接近于液晶层。 In the IPS mode liquid crystal display device of Japanese Unexamined Patent Publication No. 10-186407 discloses, a layer between the data line and the common electrode layer is formed a data line formed a common electrode is formed electrically insulating layer, and the position of the common electrode layer than the data line layer closer to the liquid crystal layer. 公共电极在一个特定的区域上与数据线的特定区域重叠。 The common electrode to overlap the data line in a specific area on a specific area. 公共电极完全与数据线重叠,防止电场的泄露,并且公共电极部分地与数据线重叠,可以保证减少数据线和公共电极间形成的寄生电容。 Common electrodes completely overlap the data line, to prevent leakage of the electric field, and the common electrode partially overlapping the data line can be reduced to ensure that the parasitic capacitance between the data line and the common electrode is formed.

然而,日本待审专利公开号10-186407并没有披露和建议包含透明材料的公共电极。 However, Japanese Unexamined Patent Publication No. 10-186407 does not disclose and recommend common electrode comprises a transparent material.

在日本待审专利公开号9-236820披露的IPS模式液晶显示器件中,每个对置电极都是由平行于源总线(相当于本发明的数据线)的薄带型电极组成,通过它像素信号被传输给像素电极。 In the IPS mode liquid crystal display device of Japanese Unexamined Patent Publication No. 9-236820 disclosure, each of the counter electrode are made parallel to the source bus line (data line corresponding to the present invention) is composed of strip-type electrode, by which a pixel signal is transmitted to the pixel electrode. 对置电极和源总线通过夹在他们中间的透明绝缘层彼此堆叠。 The counter electrode and the source bus line by sandwiching them transparent insulating layer stacked on each other. 对置电极和源总线相对于光穿透液晶显示器件的方向上位于相同的位置。 The counter electrode and the source bus line at the same position with respect to the direction of the light penetrating the liquid crystal display device.

根据日本待审专利公开号9-236820的描述,如果对置电极和像素电极由透明材料制成,有可能增加像素的开孔率,。 The description of Japanese Unexamined Patent Publication No. 9-236820, if made of transparent material for the counter electrode and the pixel electrode, it is possible to increase the aperture ratio of a pixel. 然而,该公开的专利进一步描述,由于透明材料具有高阻抗,将产生电压差,干扰了驱动电极显示图像,而且透明电极非常昂贵。 However, this patent disclosure further described, since the transparent material has a high impedance, the voltage difference is generated, interference with the driving electrode to display an image, and a transparent electrode is very expensive.

日本待审专利公开号6-202127披露的IPS模式液晶显示器件设计了一个由有源器件组成的驱动器,它的特点是将图像信号传输给有源器件的信号线被覆盖在一个面对液晶层的区域上,其中电导体和电绝缘体相互叠加。 Japanese Unexamined Patent Publication No. IPS mode liquid crystal display device designed 6-202127 discloses a device composed by the active drive, which is characterized by transmitting the image signal to the signal line is covered by the active device in a face of the liquid crystal layer the region in which the electrical conductor and an electrical insulator superimposed on each other.

然而该公开的专利并没有披露和建议信号线由透明电极屏蔽。 However, the disclosed patent does not disclose and recommend a signal line is shielded by a transparent electrode.

日本待审专利公开号10-307295披露的IPS模式液晶显示器件的特点是多个子区用于补偿彩色图像。 Japanese Unexamined Patent Publication No. 10-307295 discloses the characteristics of IPS mode liquid crystal display device is a plurality of sub-regions for compensating a color image. 例如,该公开的专利建议了一种可以防止图像变色的方法,包括在第一和第二子区中产生具备不同方向电场的步骤,因此可以在第一和第二子区中使液晶分子以不同方向旋转,保证了当观者斜视液晶显示器件的时候,第一和第二子区的光学特点可以相互得到补偿。 For example, disclosed in the patent it suggests a method of preventing discoloration of the image may be, includes the step includes generating an electric field in different directions in the first and second sub-regions, therefore the first and second sub-zone that the liquid crystalline molecules different directions of rotation, ensures that when the viewer perspective view of the liquid crystal display device, the optical characteristics of the first and second sub-region can be compensated each other.

上述公开专利中披露的IPS模式液晶显示器件的目的是增加开孔率,提高显示图像的亮度。 Object of the IPS mode liquid crystal display device disclosed in the patent disclosure is to increase the opening ratio and improve the brightness of the display image.

因为在数据线和对置电极或公共电极之间存在着电压差,所以因为该电压差会产生电场。 Because there is a voltage difference between the data line and the counter electrode or the common electrode, because the voltage difference will generate an electric field. 如果该电场接触到位于像素电极和公共电极之间受该电场影响的显示区,液晶分子中的定向将受到干扰。 If contact with the display area to the electric field located between the pixel electrode and the common electrode by the influence of the electric field, the orientation of the liquid crystal molecules will be disturbed. 例如,当在屏幕上显示一个有黑色背景的白色窗口时,会引发一种问题,称作垂直串扰,其中应该显示黑色的像素与驱动像素显示白色的数据线结合,会显示出灰色。 For example, when displaying a black background with a white window on the screen, it causes a problem will be referred to as vertical crosstalk, which should display a black pixel and a white pixel of the display data driving wire bonding, it will show gray.

为了避免垂直串扰问题,需要采用公共电极来终止电场,该公共电极具有在数据线的对置边处向外延伸一定的宽度,以便屏蔽与数据线相关的电场,或者使用其电压不会影响图像的电极覆盖数据线,例如公共电极。 In order to prevent vertical crosstalk, the common electrode need to terminate the electric field, the common electrode extending outwardly on opposite sides of the data line at a certain width, in order to shield the electric field associated with the data line, or using a voltage which does not affect the image the electrodes cover the data line, for example a common electrode.

为了增加开孔率,最好应该使用公共电极覆盖数据线,例如后者提到的。 In order to increase the opening ratio, it is advisable to use a common electrode covers the data line, for example, mentioned in the latter.

然而上述公开的专利建议的常规液晶显示器件伴随着不能完全屏蔽和降低通过使用包含不透光材料的公共电极所导致的光的减少而产生的影响。 However, the aforementioned conventional liquid crystal display device disclosed in the accompanying patent suggests not completely shielded by reducing the influence of light and reduce the common electrode containing opaque material resulting generated.

上述公开的专利建议的常规液晶显示器件的目的是提高开孔率,然而仍然需要进一步提高开孔率。 Object of the above conventional liquid crystal display device disclosed in the patent is to increase the open porosity recommendation, but is still a need to further improve the aperture ratio.

发明概述鉴于常规液晶显示器件中存在的上述问题,本发明的目的是提供一种平面开关(IPS)模式液晶显示器件,它可以解决垂直串扰问题,同时提高开孔率。 SUMMARY In view of the above problems of the conventional liquid crystal display device is present, the object of the present invention is to provide an in-plane switching (IPS) mode liquid crystal display device, which can solve the problem of vertical crosstalk, while improving the aperture ratio.

特别是与上述常规液晶显示器件比较,本发明的第一个目的是提供IPS模式的液晶显示器件,它可以防止垂直串扰的发生,而不会降低开孔率。 Especially compared with the above conventional liquid crystal display device, a first object of the present invention is to provide an IPS mode liquid crystal display device which can prevent the occurrence of vertical crosstalk, without decreasing the opening ratio.

为了实现上述第一个目的,根据本发明,数据线设计成用透明公共电极重叠,用于屏蔽从IPS液晶显示器件中的数据线泄露的电场。 To achieve the above first object, according to the present invention, the data line is designed to overlap with the transparent common electrodes for shielding the electric field that leaks from the IPS liquid crystal display device of the data line. 然而这个结构仍然伴随着这样的问题,正如上述日本待审专利公开号9-236820指出的那样,由于透明材料的高阻抗,可能会产生电压差,从而防止电极正常地受驱动以显示图像。 However, this structure is still accompanied by problems such as the above-described Japanese Unexamined Patent Publication No. 9-236820 noted above, since high resistance transparent material, may generate a voltage difference, so as to prevent the electrode is normally driven to display an image. 因此,本发明的第二个目的是提供一种IPS模式液晶显示器件,其由透明电极组成的公共电极与数据线重叠,而公共电极可以具有降低的阻抗。 Accordingly, a second object of the present invention is to provide an IPS mode liquid crystal display device, a transparent electrode which is composed of the common electrode and overlapping the data line and the common electrode may have a reduced impedance.

为了实现第二个目的,与数据线重叠的透明电极通过每个像素的接触孔与公共电极线电连接。 To achieve the second object of the transparent electrode, the data line overlaps the common electrode line is electrically connected through a contact hole in each pixel.

即使上述目的得以实现,开孔率的降低问题仍然没有得到解决。 Even though the above object is achieved, reducing the problem of open porosity remains unresolved. 因此,本发明的第三个目的是提供一种IPS模式液晶显示器件,它能够省略不透光的薄膜,诸如,在常规IPS模式液晶显示器件中经常使用的、用于防止在显示图像上出现由于电场泄露造成的垂直串扰而设置的黑基底膜。 Accordingly, a third object of the present invention is to provide an IPS mode liquid crystal display device, it is possible to omit opaque film, such as is often used in conventional IPS mode liquid crystal display device, for preventing the image appears on the display Since the leakage electric field caused by the vertical crosstalk is provided a black substrate film.

为了实现上述第三个目的,根据本发明的IPS模式液晶显示器件,当以平面方式观察时,面对数据线的黑基底层被设计成具有宽度小于与数据线重叠的公共电极的宽度,而不透光薄膜被设计成不形成在与数据线重叠的公共电极和位于毗邻公共电极的像素电极之间。 To achieve the above third object, the IPS mode liquid crystal display device of the present invention, when viewed in a planar manner, the base layer facing the black data lines is designed to have a width smaller than the common electrode and overlapping the data line width, and opaque film is designed not to be formed between the common electrode and overlapping the data line and the pixel electrode located adjacent to the common electrode.

正如上述日本待审专利公开号9-236820所指出的,这里存在一个问题,即透明的电极非常昂贵。 As the above-mentioned Japanese Unexamined Patent Publication No. 9-236820 noted, there exists a problem in that the transparent electrode is very expensive. 因此,本发明的第四个目的是提供一种IPS模式液晶显示器件,其中的透明电极可以低成本制作。 Accordingly, a fourth object of the present invention is to provide an IPS mode liquid crystal display device, wherein the transparent electrode may be manufactured at low cost.

为了实现第四个目的,透明电极由ITO组成,在制造ITO透明电极、同时带有由ITO组成的端子的过程中不会增加制作透明电极的步骤。 To achieve the fourth object, a transparent electrode composed of ITO, the ITO transparent electrode manufactured at the same time with terminal composed of ITO does not increase during the step of forming the transparent electrode.

正如上述日本待审专利公开号10-186407所指出的,如果公共电极完全与数据线重叠,则数据线和常规电极之间寄生电容增加的问题仍然没有得到解决。 As the above-mentioned Japanese Unexamined Patent Publication No. 10-186407 noted, if the common electrodes completely overlap the data line, the data line and the parasitic capacitance between the electrodes increases conventional problems remain unresolved. 因此,本发明的第五个目的是提供一种IPS模式液晶显示器件,其数据线几乎与公共电极完全重叠,而不会在数据线和公共电极之间增加寄生电容。 Accordingly, a fifth object of the present invention is to provide an IPS mode liquid crystal display device which is almost completely overlaps the data line and the common electrode, without increasing a parasitic capacitance between the data line and the common electrode.

为了实现第五个目的,由ITO组成的公共电极形成在比带有被夹在其间的层间绝缘层的数据线更接近液晶层的层中,该层间绝缘层是由具有低介电常数的有机材料制成。 To achieve the fifth object, a common electrode composed of ITO is formed than in the interlayer insulating layer interposed therebetween with the data line closer to the liquid crystal layer in the layer, the interlayer insulating layer having a low dielectric constant made of an organic material.

虽然上述公开专利没有指出这一点,如果屏蔽数据线的公共电极被设计成由普通金属材料而不是ITO制成,则与带有由ITO组成的公共电极的液晶显示器件相比,最终的液晶显示器件的可靠性要低。 While the above noted patent does not disclose that, if the common electrode shield the data line is designed to be made instead of ITO, the metal material as compared to a normal liquid crystal display device having a common electrode composed of ITO, the final liquid crystal display lower reliability of the device. 所以,本发明的第六个目的是提供IPS模式的液晶显示器件,其数据线使用更可靠的透明材料屏蔽。 Therefore, a sixth object of the present invention is to provide an IPS mode liquid crystal display device, the data line using a transparent material shielded more reliably.

根据本发明的一个方面,提供了一种平面开关模式有源矩阵型液晶显示器件,包括(a)第一基板,(b)与第一基板对置的第二基板和(c)夹在第一和第二基板之间的液晶层,其中第一基板包括(a1)带有栅极、漏极和源极的薄膜晶体管(a2)与要驱动的像素相关联的像素电极,(a3)向其施加参考电压的公共电极,(a4)数据线,(a5)扫描线,和(a6)公共电极线;其栅极与扫描线电连接,漏极与数据线电连接,源极与像素电极电连接,并且公共电极与公共电极线电连接,借助基本上与第一基板的平面平行、并施加在像素电极和公共电极之间的电场,液晶层中的液晶分子轴沿与第一基板平行的平面旋转,从而显示一定的图像。 According to one aspect of the present invention, there is provided an in-plane switching mode active matrix type liquid crystal display device, comprising (a) a first substrate, (b) a first substrate and a second substrate opposed and (c) are sandwiched between the and a liquid crystal layer interposed between the second substrate, wherein the first substrate includes a pixel electrode (a1) having a gate, drain and source of the thin film transistor (a2) to be associated with the pixel is driven, (A3) to a common electrode for applying a reference voltage, (A4) the data line, (A5) scanning lines, and (A6) the common electrode line; a gate electrically connected to the scan line, the data line is electrically connected to the drain electrode, the source electrode and the pixel electrode electrically connected, and the common electrode and the common electrode line is electrically connected, by means of a plane substantially parallel to the first substrate, and applying an electric field between the pixel electrode and the common electrode, the liquid crystal molecular axis in the liquid crystal layer is parallel to the first substrate plane rotation, to thereby display certain images. 公共电极由透明材料组成,并形成在比数据线更接近于液晶层的层面上,除了位于扫描线附近的数据线的区域外,公共电极与其间夹有绝缘层的数据线完全重叠。 The common electrode made of a transparent material, and is formed on the liquid crystal layer is closer than the level of the data lines, except in the region of the data line in the vicinity of the scanning lines, the common electrode and the data line sandwiched therebetween an insulating layer completely overlaps. 该平面开关模式有源矩阵型液晶显示器件进一步还包括在公共电极完全与数据线重叠的区域中的不透光层,,该不透光层形成在第二基板上、或者第一基板上,以便使得该不透光层位于比数据线更接近液晶层的位置,并且面对数据线,该不透光层由黑基底层、或者由具有比与数据线重叠的公共电极的宽度小的多层彩色层组成。 The in-plane switching mode active matrix type liquid crystal display device further comprising a further opaque layer of the common electrode and the data line is completely overlapped region ,, the opaque layer is formed on the second substrate, or on the first substrate, so that the opaque layer is positioned such that the data line is closer than the position of the liquid crystal layer, and facing the data line, the base layer by a black opaque layer, or a width ratio of the data having a common electrode line overlapped much smaller layer color layer.

上述平面开关模式有源矩阵型液晶显示器件实现了上述第一到第三目标。 The above-plane switching mode active matrix liquid crystal display device achieves the above first to the third target. 特别是,该平面开关模式有源矩阵型液晶显示器件可以,(a)防止垂直串扰,而不会降低开孔率,(b)与公共电极电连接的透明电极与数据线重叠,并且公共电极可以具备低阻抗,(c)可以省略不透光薄膜,例如在常规IPS模式液晶显示器件中使用的、用于防止因为电场泄露所致的在显示图像时出现的垂直串扰的黑基底膜。 In particular, the in-plane switching mode active matrix type liquid crystal display device can be, (A) to prevent vertical crosstalk, without decreasing the opening ratio, (b) a transparent electrode is electrically connected to the common electrode and overlapping the data line, and the common electrode may include a low impedance, (c) a light-transmitting film can be omitted, for example, in conventional IPS mode liquid crystal display device, for preventing vertical crosstalk occurs because the electric field due to the leakage of the base film at the time of black display image.

下面说明为什么上述平面开关模式有源矩阵类型的液晶显示器件可以实现第一到第三目标的原因。 The following explains why the above-plane switching mode active matrix type liquid crystal display device of the first to third reason the target can be achieved.

图1是上述常规液晶显示器件10A的部分剖面图。 1 is a partial sectional view of the above-described conventional liquid crystal display device 10A. 为了简化说明,图1仅仅示出了部分必要内容。 To simplify the description, FIG. 1 shows only part of the necessary elements.

液晶显示器件10A包括有源器件基板11A、对置基板12A和夹在有源基板11A和对置基板12A之间的液晶层13A。 The liquid crystal display device comprising an active device substrate 10A 11A, 12A and the counter substrate sandwiching a liquid crystal layer and the active substrate 11A 13A 12A of the counter substrate.

对置基板12A包括起到可以阻断不必要光的不透光膜的作用的黑基底层17A、部分覆盖黑基底层17A的彩色层18A、覆盖黑基底层17A和彩色层18A的整体覆盖层19A、在整体覆盖层19A上完全形成的定向膜20A。 12A includes the opposite substrate an opaque film acts to block unwanted light may be a black substrate layer 17A, the base layer 17A partially covers the black color layers 18A, 17A and the base layer covering the black color of the entire cover layer layer 18A 19A, the alignment film 20A is formed entirely over the entire cover layer 19A.

有源器件基板11A包括:形成在玻璃基板(未示出)上的公共电极26A、在玻璃基板上形成的夹层绝缘膜25A覆盖公共电极26A、在夹层绝缘膜25A上形成的数据线24A、在夹层绝缘膜25A上形成的像素电极27A、覆盖数据线24A和像素电极27A的、在夹层绝缘膜25A上形成的钝化膜37A、以及在钝化膜37A上形成的定向膜31A。 11A active device substrate comprising: forming on a glass substrate (not shown) of the common electrode 26A, an interlayer insulating film formed on the glass substrate to cover the common electrode 25A 26A, 24A formed in the data lines on the interlayer insulating film 25A, in a pixel electrode formed on the interlayer insulating film 27A. 25A, 24A cover the data line and the pixel electrode 27A, the passivation film 37A is formed on the interlayer insulating film 25A, and the alignment film 31A is formed on the passivation film 37A.

在图1所示的液晶显示器件10A中,在数据线24A附近形成的公共电极26A必须做得足够宽,以便在此吸收从数据线24A中泄露的电场。 In the liquid crystal display device 10A shown in FIG. 1, the common electrode 26A is formed in the vicinity of the data line 24A must be made wide enough to absorb this field leaked from the data line 24A. 因为公共电极26A由构成栅极线的不透明材料组成,所以不可避免地,限定开口OP的区域从公共电极26A的右边(直边?)向内延伸。 Since the common electrode 26A composed of an opaque material composed of the gate line, so inevitably, the region defining the opening OP of the common electrode 26A from the right (straight edge?) Extending inwardly.

此外,对于黑基底层17A来说还需要做得比完全覆盖数据线24A的宽度更宽,以便阻断从数据线24A和公共电极26A之间的缝隙泄露的光线S。 In addition, the black base layer 17A is larger than was needed to completely cover the data line 24A of a larger width, so as to block the light leaked from the gap between the data line and the common electrode 24A 26A S.

例如,考虑到在有源器件基板11A和起滤色器作用的对置基板12A之间的对准误差,将液晶显示器件10A中的黑基底层17A设计成可以比数据线24A和公共电极26A之间的缝隙延伸出8μm或更大的宽度。 For example, taking into account the alignment errors between the active device and the substrate 11A plays the role of a color filter of the counter substrate. 12A, the black base layer 17A of the liquid crystal display device 10A can be designed than the data lines and the common electrode 26A 24A extending the gap between the width of 8μm or more.

如上所述,在常规液晶显示器件10A中增加开孔率是十分困难的,因为液晶显示器件10A只能有一个有限的区域作为开口OP,所以需要让黑基底层17A延伸出上述缝隙之外。 As described above, increasing the opening ratio in the conventional liquid crystal display device 10A is very difficult, because the liquid crystal display device 10A can have only a limited area of ​​the opening as the OP, it is necessary to make the black base layer extends beyond the slot 17A.

图2是一个根据本发明设计的液晶显示器件的部分剖面图。 FIG 2 is a partial sectional view of a liquid crystal display device according to the present invention is designed. 与图1类似,图2为了简化说明的目的,仅仅示出了需要说明的部分。 Similar to FIG. 1, FIG. 2 for purposes of simplicity of illustration, only shows a portion of Note.

液晶显示器件10包括有源器件基板11、对置基板12和夹在有源器件基板11和对置基板12之间的液晶层13。 The liquid crystal display device 10 includes an active device substrate 11, counter substrate 12 and sandwiched between the active device substrate 11 and the counter substrate 12 liquid crystal layer 13.

对置基板12包括黑基底层17、部分覆盖黑基底层17的彩色层18、覆盖黑基底层17和彩色层18的整体覆盖层19、完全覆盖在整体覆盖层19上的定向膜20。 Counter substrate 12 includes a black base layer 17, the colored layer partially covering the base layer 17 black 18 black covers the entire cover layer 19 the base layer 17 and the colored layer 18 completely covers the entire alignment film 20 of the cover layer 19.

有源器件基板11包括第一夹层绝缘膜23、在第一夹层绝缘膜23上形成的数据线24、在第一夹层绝缘膜23上形成的、覆盖数据线24的第二夹层绝缘膜25、在第二夹层绝缘膜25上形成的公共电极26、在第二夹层绝缘膜25上形成的像素电极27、和在第二夹层绝缘膜25上形成的、覆盖公共电极26和像素电极27的定向膜31。 Active device substrate 11 includes a first interlayer insulating film 23, 24 formed on the first interlayer insulating film 23 is formed on the data line in the first interlayer insulating film 23 covering the data line 24 of second interlayer insulating film 25, a common electrode formed on the second interlayer insulating film 2526, a pixel electrode formed on the second interlayer insulating film 2527, and is formed on the second interlayer insulating film 25 covering the common electrode 26 and the orientation of the pixel electrode 27 film 31.

公共电极26设计成完全与数据线24重叠,并且黑基底层17设计成具有比公共电极26的宽度小的宽度。 The common electrode 26 is designed to be completely overlapped with the data line 24, and the black base layer 17 is designed to have a width smaller than the width of the common electrode 26. 公共电极26和像素电极27两者都是由氧化铟锡(ITO)材料组成,这是一种透明材料。 Both the pixel electrodes 26 and the common electrode 27 are made of indium tin oxide (ITO) material, which is a transparent material.

根据液晶显示器件10,从数据线24泄露的电场完全被位于数据线24上的公共电极26所屏蔽。 The liquid crystal display device 10, the electric field from data line 24 leakage is completely positioned on the common electrode 24 shielded by the data line 26. 因此,如图2所示,可以得到一个限定开口OP的区域,它从公共电极26的右边(直边?)向内延伸,使得开口OP比图1所示的常规液晶显示器件10A中得到的开口OP宽。 Thus, as shown in FIG. 2, a region can be defined in the opening OP, it (the straight edge?) From the right side of the common electrode 26 extends inwardly, so that the ratio of the opening OP view of a conventional liquid crystal display device 1 shown in FIG. 10A is obtained wide opening OP.

即,根据本发明的液晶显示器件可以具有比常规液晶显示器件10A更大的开孔率。 That is, the liquid crystal display device according to the present invention may have a larger aperture ratio than a conventional liquid crystal display device 10A.

此外,在根据本发明的液晶显示器件10中,只要防止从位于黑基底层17附近的像素泄露光,就可以有效地防止光泄露。 Further, the light leakage in the liquid crystal display device according to the present invention 10, as long as to prevent light leakage from a black pixel is located near the base layer 17, can be effectively prevented. 因此,不再需要黑基底层17具有比数据线24宽的宽度,即使在考虑到有源器件基板11和对置基板12的误对准的情况下。 Thus, no need for a black base layer 17 having a wider width than the data line 24, even in consideration of the active device substrate 11 and the counter substrate 12 of the misalignment.

例如,如果黑基底层17具有6μm或更大的宽度,只要数据线24与黑基底层17重叠,就可能让黑基底层17有效地阻断光。 For example, if the black base layer 17 having a width of 6μm or more, as long as the data line 24 overlap with the black base layer 17, base layer 17 can make black and effectively blocks the light.

图3是一个曲线图,示出了模拟从数据线24泄露的电场是如何在公共电极26完全与数据线24重叠的液晶显示器件中得到屏蔽的结果。 Figure 3 is a graph showing how the simulation result obtained from the electric field shielding data line 24 leaks to the data line 26 is completely liquid crystal display device 24 overlaps the common electrode.

在该模拟过程中,计算出了电位的轮廓和光通过单个单元中的液晶显示器件的速率,假定各像素完全是黑色的,0V电压施加在像素电极27和公共电极26上,5V电压施加在漏极上。 In this simulation, the computed outline potential and light throughput rate of a single unit of the liquid crystal display device, assumed that each pixel is completely black, 0V voltage is applied to the pixel electrode 27 and the common electrode 26, 5V voltage is applied to the drain pole.

如图3所示,通过液晶显示器件的光线的速率Z保持为0。 As shown in FIG. 3, Z 0 is maintained by the rate of light of the liquid crystal display device. 这意味着,从数据线24泄露的电场完全被公共电极26屏蔽。 This means 26 is completely shielded from the electric field data line common electrode 24 leaks.

黑基底层17可以用具有多层彩色层的不透光层代替,在这种情况下,不再需要形成黑基底层17,因此,有可能提高液晶显示器件的加工效率。 Black base layer 17 may be replaced with an opaque layer having a multilayer color layer, in this case, the base layer 17 is formed of black is no longer necessary, and therefore, it is possible to improve the processing efficiency of the liquid crystal display device.

优选的是,公共电极与公共电极线通过每个像素中的接触孔进行电连接。 Preferably, the common electrode and the common electrode line are electrically connected through a contact hole in each pixel.

通过在每个像素中的接触孔将公共电极电连接到公共电极线,有可能减少公共电极的阻抗。 Through a contact hole in each pixel of the common electrode is electrically connected to the common electrode line, it is possible to reduce the impedance of the common electrode. 其结果是,可以解决透明材料具有高阻抗的问题。 As a result, it is possible to solve the problem of transparent material having a high impedance.

优选的是,平面开关模式有源矩阵型液晶显示器件进一步包括在与数据线重叠的公共电极下面形成的夹层绝缘膜。 Preferably, the in-plane switching mode active matrix type liquid crystal display device further comprising an interlayer insulating film formed under the common electrode and overlapping the data line. 该夹层绝缘膜包括上层和下层,上层仅形成在与数据线重叠的公共电极那部分的下面。 The interlayer insulating film comprises a lower layer and an upper layer, the upper layer of the common electrode is formed only below the portion that overlaps the data line.

通过采用这种夹层绝缘膜,也就不再需要在公共电极和数据线之间形成包含很大区域的夹层绝缘膜,它可以使公共电极几乎完全与数据线重叠,而不会增加在公共电极和数据线之间形成的寄生电容。 By using such an interlayer insulating film, it is no longer necessary to form the interlayer insulating film containing a large area between the common electrode and the data line, which can almost completely overlaps the common electrode and the data line without increasing the common electrode and a parasitic capacitance formed between the data lines.

优选的是,公共电极在对置端沿其横向比数据线宽1.5μm或更大。 Preferably, the common electrode opposed ends in its lateral width 1.5μm or larger than the data.

通过将公共电极在对置端上沿其横向设计成比数据线宽出1.5μm或更大,有可能在数据线一侧允许最大光线通过,这相当于在像素上显示白色时,通过像素的光的1/100或更小。 Design data than the lateral width direction by the common electrode on the opposite end of the 1.5μm or more, it is possible in the data line side allows light to pass through a maximum, this corresponds to the white display on a pixel by pixel 1/100 or less light.

优选的是黑基底层的宽度窄于数据线的宽度,它在整个长度上与数据线重叠。 Preferably the width of a narrow black base layer to the data line, which overlaps the data line over the entire length.

如图2所示,如果黑基底层17宽度小于数据线24的宽度,有可能使用所有通过与数据线24重叠的透明公共电极26的扩展区的光,保证了光通过面板的速率得到加强。 2, if the black base layer 17 smaller than the width of the data line 24, it is possible to use all of the light through the transparent overlay 24 and the data line 26 extension area of ​​the common electrode, to ensure that the light panel is obtained by enhancing the rate.

优选的是黑基底层形成在第二基板上,面对数据线的黑基底层的宽度等于6μm或更大。 Preferred black base layer formed on the second substrate, the width of the base layer facing the black data lines is equal to or greater 6μm.

如果黑基底层的宽度小于6μm,很多光将在数据线24上被反射,结果平面开关模式有源矩阵型液晶显示器件的屏幕在亮环境下很难看到。 If the width of the black base layer is less than 6 m, a lot of light to be reflected on the data line 24, the results of in-plane switching mode active matrix type liquid crystal display device screen is difficult to see in a bright environment.

优选的是,黑基底层与扫描线和其周围的区域、以及夹在扫描线和像素电极之间及其周围的区域重叠。 Preferably, the base layer and the black area around the scan line and, sandwiched between the scanning lines and the pixel electrode and its surrounding areas overlap.

这样保证了扫描线、和各区域可以通过黑基底层屏蔽光线。 This ensures that the scanning lines, and each region may be shielded from light by a black base layer.

优选的是像素电极由透明材料组成。 The pixel electrode is preferably made of a transparent material.

由透明材料组成的像素电极可以进一步提高开孔率。 The pixel electrode made of a transparent material may be further improved aperture ratio.

优选的是公共电极和像素电极在公共层上形成。 Preferred is a common electrode and a pixel electrode formed on the common layer.

因此,有可能在一个步骤中形成公共电极和像素电极,确保提高了产品的得率,即,根据本发明制造的平面开关模式有源矩阵型液晶显示器件无须不增加制作步骤。 Thus, it is possible to form the common electrode and the pixel electrode in one step, to ensure improved product yield, i.e., the active matrix type liquid crystal display device according to the present invention for producing plane switching mode liquid without increasing the production steps.

平面开关模式有源矩阵型液晶显示器件可以进一步包括在紧接着公共电极下面的层面上形成的夹层绝缘层,以及由在夹层绝缘层之下形成单层或多层构成的像素辅助电极,其中像素辅助电极优选地与源极电连接,并且保持与像素电极的电压相等的电压。 Plane switching mode active matrix liquid crystal display device may further include an interlayer insulating layer is formed on the common electrode level immediately below, and a pixel electrode formed of the auxiliary monolayer or multilayer under the interlayer insulating layer, wherein the pixel the auxiliary electrode is preferably electrically connected to the source and held equal to the voltage of the pixel electrode voltage. 像素辅助电极优选由不透明金属制成。 Auxiliary pixel electrode is preferably made of an opaque metal.

虽然由不透明金属制成的像素辅助电极略微减少了透射率,但是通过借助像素辅助电极将像素电极彼此进行电连接,可以在像素上下形成存储电容,从而保证了在显示图像时的更高存储电容和更高的质量。 Although the auxiliary pixel electrodes made of an opaque metal transmittance slightly reduced, but the auxiliary electrode by means of the pixel the pixel electrode electrically connected to each other, may be formed in the pixel storage capacitor vertically, thus ensuring higher storage capacitor when an image is displayed and higher quality.

优选的是,像素辅助电极至少部分地形成在形成公共电极的层的像素电极的下面,并且带有很多梳齿。 Preferably, the auxiliary pixel electrode at least partially formed in a layer below the pixel electrode, the common electrode is formed, and with a lot of comb teeth.

因为电场垂直施加给紧接着透明像素电极上的液晶,所以液晶垂直站立,其结果是,与在梳齿电极之间区域中获得的光的透射率相比,光的透射率降低。 Because the electric field perpendicular to the liquid crystal is applied immediately on the transparent pixel electrode, the liquid crystal standing upright, as a result, compared with the transmittance of light obtained in the region between the comb-shaped electrodes, the transmittance of light decreases. 因此,通过将由不透明材料组成的像素辅助电极定位在具有比像素辅助电极的透射率略微小的透射率的像素电极的下面,可以将位于像素对置边的像素辅助电极彼此进行电连接,而不会大幅度降低光的使用效率。 Thus, the auxiliary electrode is positioned by the pixel by an opaque material having the following composition is slightly smaller than the transmittance of the pixels of the pixel electrodes of the auxiliary electrode transmittance, it may be located on opposite sides of the pixel electrodes auxiliary pixel electrically connected to each other without It will greatly reduce the efficiency of use of light.

更为优选的是,平面开关模式有源矩阵型液晶显示器件进一步包括在公共电极下面紧接着的层面上形成的夹层绝缘层,以及在该夹层绝缘层之下形成的、由单层或多层构成的像素辅助电极,其中像素辅助电极与公共电极线电连接,并且保持与公共电极的电压相等的电压。 More preferably, in-plane switching mode active matrix type liquid crystal display device further comprising an interlayer insulating layer formed on the common electrode of the level immediately below, and a single layer or multiple layers formed under the interlayer insulating layer auxiliary electrode constituting a pixel, wherein the pixel electrode and the auxiliary common electrode line is electrically connected, and remains equal to the voltage of the common electrode voltage. 该像素辅助电极由不透明金属制成。 The auxiliary pixel electrode is made of an opaque metal.

与像素辅助电极类似,通过将公共电极彼此电连接,可以在像素上下形成存储电容,从而保证了显示图像时的更高存储电容和更高的质量。 Similarly the auxiliary electrode and the pixel, by the common electrode connected to each other, may be formed in the pixel storage capacitor vertically, thus ensuring a higher storage capacity and higher quality when displaying an image.

优选的是像素辅助电极形成在带有很多梳齿的公共电极的下面。 Preferably the pixel electrode is formed below the auxiliary common electrode with a lot of comb teeth.

通过将由不透明材料组成的公共辅助电极定位在具有比公共辅助电极的透射率略微小的透射率的像素电极的下面,可能将位于像素对边的公共辅助电极彼此电连接,而不会光的使用效率降低很多,然而,如果像素辅助电极设置在公共电极下面,将在公共电极和像素辅助电极之间将产生电场,结果所需的水平电场不能施加在液晶上。 By the common auxiliary electrode positioned by an opaque material below the pixel electrode has a slightly smaller than the transmittance of the common auxiliary electrode transmittance, the pixel may be common auxiliary electrode is electrically connected to each of the sides, without the use of light efficiency is much reduced, however, if the pixel electrode is provided on the auxiliary common electrode Hereinafter, an electric field generated between the common electrode and the pixel electrode auxiliary, the desired result can not exert a horizontal electric field to the liquid crystal. 因此,优选的是,像素辅助电极刚好设置在像素电极的下面,并且公共辅助电极也刚好设置在公共电极的下面。 Accordingly, it is preferable that the auxiliary electrode is a pixel immediately below the pixel electrode is provided, and the common auxiliary electrode is also provided just below the common electrode.

优选的是扫描线终端、数据线终端和公共电极线终端都是由与用透明电极组成的公共电极所构成的材料相同的材料覆盖或组成。 Preferred is a scanning line terminal, a data line terminal and the common electrode line terminal and the common electrode are made of a material with a transparent electrode composed of the same material or composition covered.

这可以确保液晶显示器件的公共电极及其终端同时形成,避免了增加在制作公共电极时所需的步骤。 This ensures that the liquid crystal display device and a common electrode terminal formed simultaneously, avoiding an increase in the production steps required for the common electrode.

平面开关模式有源矩阵型液晶显示器件优选地可以进一步包括:在子像素区中的反向旋转阻止结构,其中所有液晶分子都以相同方向旋转,而防止液晶分子以与该相同方向相反的方向旋转,其中像素辅助电极和公共电极线的至少一部分边缘是倾斜的,如果初始定向方向是以锐角进行旋转的,使得液晶分子的初始定向方向与在子像素区中的所有子区的子像素区中产生的电场重叠。 Plane switching mode active matrix liquid crystal display device preferably may further comprise: liquid crystal molecules in the same direction opposite to the reverse rotation inhibiting structure, in which all liquid crystal molecules are rotated in the same direction, while preventing the sub-pixel region rotating at least part of the edge, wherein the pixel electrode and the auxiliary common electrode line is inclined, if the initial orientation direction of rotation is at an acute angle, so that the initial orientation direction of liquid crystal molecules in the sub pixel area in all sub-regions of the sub-pixel region the electric field generated in the overlap.

通过防止液晶分子的分子轴反向旋转,就有可能实现对液晶显示器件显示质量和可靠性的改善。 By preventing the molecular axis of the liquid crystal molecules in the reverse rotation, it is possible to achieve improved reliability and display quality of the liquid crystal display device.

优选的是,在第一基板上形成将像素电极与源极电连接的一个第一接触孔,,以及将将公共电极与公共电极线电连接的第二接触孔,该第一和第二接触孔的内表面均用金属膜覆盖。 Preferably, a first contact hole formed in the pixel electrode and the source electrode is electrically connected to the second contact hole ,, and the common electrode and the common electrode line is electrically connected to the first substrate, the first and second contact the inner surface of the hole are covered with a metal film.

通过在第一和第二接触孔的内表面覆盖金属膜,可以降低均由透明金属制成的公共电极和公共电极线之间的电阻,从而提高了显示图像的均匀性。 By covering the inner surface of the first metal film and the second contact hole, the resistance can be reduced between the transparent common electrode made of a metal and a common electrode line by, thereby improving the uniformity of the display image.

例如,像素电极可以由形成数据线的第二金属层形成。 For example, the pixel electrode may be formed by the second metal layer forming the data lines.

由于像素电极和公共电极彼此形成在不同的层面上,像素电极和公共电极不会彼此短路,因此确保了生产成品率的提高。 Since the pixel electrode and the common electrode are formed on different levels with each other, the pixel electrode and the common electrode is not short-circuited to each other, thus ensuring the production yield improved.

优选的是,像素电极形成在形成漏极的第二金属层上,图像也在这个区域中显示,除了由透明金属组成、并与数据线重叠的部分之外的公共电极的部分形成在形成栅极的第一金属层上。 Preferably, a pixel electrode formed on the second metal layer forming the drain, an image is displayed also in this area, in addition to portions of the common electrodes other than a transparent metal, and overlaps the data line forming the gate portion is formed a first metal layer on the electrode.

尽管没有示出,在有源器件基板11和对置基板12之间还是形成了间隙,以便确保液晶层13的厚度,并且在有源器件基板11和对置基板12之间的液晶层13的周围进行密封,避免液晶分子的泄露。 Although not shown, between the active device substrate 11 and the counter substrate 12 is formed a gap, in order to ensure the thickness of the liquid crystal layer 13 and the substrate 11 and the active device 12 is a liquid crystal layer interposed between the counter substrate 13 sealing around to avoid leakage of the liquid crystal molecules.

在图8中,第二夹层绝缘膜25设计成具有第一膜25a和第二膜25b的多层结构,而在图9中,第二夹层绝缘膜25被设计成具有第一膜25a的单层结构。 In FIG. 8, a second interlayer insulating film 25 is designed to have a multilayer structure of a first film and the second film 25a and 25b, and in FIG. 9, the second interlayer insulating film 25 is designed as a single film 25a having a first layer structure. 下面参考图8进行说明。 8 will be described below with reference to FIG. 当第二夹层绝缘膜25具有单层结构时,第一膜25a可以被认为是第二夹层绝缘膜中的下层,同时第二膜25b可以被认为是第二夹层绝缘膜中的上层。 When the second interlayer insulating film 25 has a monolayer structure, the first film 25a may be considered a second interlayer insulating film in the lower layer, while the second film 25b may be considered the upper second interlayer insulating film.

如图8和图4所示,公共电极线26a和26b由第一金属层构成,沿数据线24平行延伸,并且在其周围被施以公共电极26的电压。 8 and FIG. 4, the common electrode lines 26a and 26b is constituted by a first metal layer extending along the data line 24 is parallel, and the common electrode 26 is applied with a voltage at its periphery.

如图4所示,由透明电极构成的像素电极27通过接触孔39b与像素辅助电极35电连接。 4, the pixel electrode is a transparent electrode 27 formed of the contact hole 39b is electrically connected to the pixel electrode 35 through the auxiliary. 该像素辅助电极35包括第二金属层,并且与薄膜晶体管30的源极30b整体形成。 The pixel 35 includes a second auxiliary electrode layer of metal, and integrally formed with the thin film transistor 30 source electrode 30b.

在基于第一实施方案的平面开关模式有源矩阵型液晶显示器件10中,在根据通过扫描线28传输的扫描信号选择、并通过数据线24传输的数据信号被写入的像素中,在公共电极26和像素电极27之间的、产生与透明基板16和22平行的电场,同时液晶层中的液晶分子的定向方向根据平行于透明基板16和22平面中的电场进行旋转,从而,在液晶显示器件10的显示屏上显示图像。 In the active matrix type liquid crystal display device based on plane switching mode of the first embodiment 10, the scanning selection signal transmitted through the scan line 28, and the data is written in the data signal transmission line 24 according to the pixels in common and the electrode, the transparent substrate 16 and generates an electric field between the parallel 22 27 26 pixel electrode, while the alignment direction of liquid crystal molecules in the liquid crystal layer in accordance with an electric field is rotated parallel to the transparent substrate 16 and the plane 22, thereby, the liquid crystal on the display screen of the display device 10 displays an image. 在图4中,被公共电极26和像素电极27包围的垂直的长区被称为柱。 In FIG. 4, the common electrode 26 and the vertical long areas surrounded by the pixel electrode 27 called column. 在平面开关模式有源矩阵型液晶显示器件10中,公共电极26和像素电极27两者都由氧化铟锌(ITO),即透明材料形成的。 In-plane switching mode active matrix liquid crystal display device 10, both of the common electrode 26 and the pixel electrode 27 consists of indium zinc oxide (ITO), i.e. a transparent material.

如图7和8所示,平面开关模式有源矩阵型液晶显示器件10可以设计成在第二夹层绝缘膜25下面包括像素辅助电极35。 7 and 9, the in-plane switching mode active matrix type liquid crystal display device 810 may be designed to be below the second interlayer insulating film 25 auxiliary electrode 35 comprises a pixel. 该像素辅助电极35与薄膜晶体管30的源极30b整体形成,该薄膜晶体管形成在第一夹层绝缘膜23上的第二金属层上。 The pixel electrode 35 and the auxiliary source electrode 30b of the thin film transistor 30 is formed integrally, the thin film transistor formed on the second metal layer on the first interlayer insulating film 23.

如图7所示,像素辅助电极35由第一部分35a、第二部分35b、和第三部分35c构成,其中第一部分35a与由第一金属层形成的公共电极线26b重叠,并且与公共电极线26b一道定义了存储电容;第二部分35b与由第一金属层形成的公共电极线26a重叠,并且与公共电极线26a一道定义了存储电容;第三部分35c与数据线24平行延伸,并且形成在第二夹层绝缘膜25上形成的像素电极27的下面,并且第一和第二部分35a和35b彼此相互连接。 As shown in FIG 7, the pixel electrode 35 by the first auxiliary portion 35a, second portion 35b, and a third portion 35c constitute, wherein the first portion 35a overlap the common electrode line 26b formed by the first metal layer, and the common electrode line 26b defines a storage capacitor; the second part 35b and the common electrode line formed by overlapping a first metal layer 26a, and the common electrode line 26a defines a storage capacitor; the third portion 24 extends in parallel with the data line 35c, and is formed below the pixel electrode formed on the second interlayer insulating film 2527, and the first and second portions 35a and 35b connected to each other. 像素辅助电极35的呈“I”形像素辅助电极35的第一到第三部分35a、35b和35c是由在第一夹层绝缘膜23上的不透明的第二金属层形成的。 The auxiliary electrodes are the pixel "I" shaped first pixel electrode 35 to the auxiliary third portion 35a, 35b and 35c are formed of an opaque metal layer on the second interlayer insulating film 23 of the first 35. 正如通过图8可以明了的,薄膜晶体管30的漏极30a和源极30b也由不透明的第二金属层构成。 As can be appreciated by FIG. 8, the drain 30a and the source electrode 30b of the TFT 30 be formed of an opaque second metal layer. 源极30b与像素辅助电极35电连接。 The pixel electrode 30b is connected to the source of the auxiliary electrode 35.

尽管在像素辅助电极35是由不透明金属构成时,光的透射率会略有降低,但是,当从像素的平面图观看时,通过将第一到第三部分35a、35b和35c彼此电连接,有可能在其上下两侧形成存储电容,从而保证了存储电容的增加和图像显示时的稳定性。 Although the auxiliary electrode 35 when the pixel is constituted by an opaque metal, the transmittance of light will be slightly reduced, but, when viewed from a plan view of a pixel, by 35a, 35b and 35c are electrically connected to the first to third part, there is storage capacitor may be formed on upper and lower sides thereof, thus ensuring the stability of the storage capacitor increases and an image display.

应该注意的是,像素辅助电极35的形状不局限于图7中示出的“I”型。 It should be noted that the shape of the pixel is not limited to the auxiliary electrode 35 in FIG. 7 "I" type illustrated. 像素辅助电极35可以设计成任何形状,除非它位于像素电极27的下面。 Auxiliary pixel electrode 35 may be designed in any shape, unless it is located below the pixel electrode 27.

虽然图7没有示出,但是公共辅助电极可以由在第一夹层绝缘膜23上的第二金属层构成,并且与都是由第一金属层构成的公共电极线26a和26b、以及公共电极26电连接。 Although not shown in FIG. 7, the common auxiliary electrode may be formed by a second metal layer on the first interlayer insulating film 23, and the common electrode line is composed of the first metal layer 26a and 26b, and the common electrode 26 the electrical connection.

如图8所示,薄膜晶体管30的栅极30c由第一金属层构成。 8, the gate electrode 30c thin film transistor 30 is constituted by a first metal layer.

从像素的平面图可以看出,通过将公共电极26彼此电连接,有可能在其上下两侧形成存储电容,从而保证了存储电容的增加和图像显示时的稳定性。 As can be seen from the plan view of the pixel, the common electrode 26 by electrically connected to each other, it is possible to form a storage capacitor at its upper and lower sides, thus ensuring the stability of the storage capacitor increases and an image display.

如图4和图5所示,公共电极26形成的层位于数据线24的上面,并且,除了在数据线24与扫描线28交叉的区域和该区域的周围区域外,所述公共电极与数据线24完全重叠。 4 and 5, the common electrode layer 26 is formed above the data line 24 is located, and, in addition to the data lines 24 intersecting with the scanning lines 28 and a region around an outer region of the region, the common electrode and the data line 24 is completely overlapped.

具体地,如图11所示,假设L(D)表示数据线24的宽度,L(COM)表示公共电极26的宽度,L(COM)大于L(D);此外数据线24的宽度L(D)完全被公共电极26的宽度L(COM)所覆盖。 Specifically, as shown in FIG. 11, suppose L (D) represents the width of the data line 24, L (the COM) represents the width of the common electrode 26, L (the COM) is greater than L (D); in addition the width of the data lines 24 L ( D) completely covered by L (COM) width of the common electrode 26.

L(COM)>L(D)在图4中,由于在数据线24和扫描线28交叉的区域和该区域周围的区域中形成了高的台阶,所以,在这些区域中为了避免短路,公共电极26不能与数据线24重叠。 L (COM)> L (D) in FIG. 4, since a high level in the area of ​​the region and the region around the data line 24 and the scanning line 28 intersect, so in these areas in order to avoid a short circuit, the common electrode 26 and data line 24 can not overlap.

如前所述,从平面图的上部看,在上述数据线24上形成的黑基底层17被设计成其宽度小于公共电极26的宽度,并且在与数据线24重叠的公共电极26和毗邻公共电极26形成的像素电极27之间没有不透光膜。 As described above, from the top plan view, a black base layer formed on the data line 24 17 is designed to have a width smaller than the width of the common electrode 26, 24 and overlapping the data line 26 and the common electrode adjacent to the common electrode the pixel electrode 26 is formed between the light-transmitting film 27 no. 此外,黑基底层17被设计成宽度小于数据线24的宽度,并且整个与数据线24重叠。 In addition, the black base layer 17 is designed to be smaller than the width of the data line 24, and the data line 24 overlap across.

即,根据图12所示,假定L(D)表示数据线24的宽度,而L(BM)代表黑基底层17的宽度,宽度L(D)大于L(BM),同时L(BM)完全与宽度L(D)重叠。 That is, as shown, assuming L (D) represents the width of the data line 24, and L (BM) width indicated by the black base layer 17, the width L (D) according to FIG. 12 is larger than L (BM), while L (BM) is fully the overlap width L (D).

L(D)>L(BM)通过将黑基底层17设计成宽度小于数据线24的宽度,就可能利用穿过延伸出数据线24的透明公共电极26的延伸部分的光,从而保证穿过面板的光线的透射率得到加强。 L (D)> L (BM) by a black base layer 17 is designed to be smaller than the width of the data line 24, it is possible to use light passing through the extension portion extending a transparent common electrode 24 of the data line 26, thereby ensuring through the light transmittance of the panel to be strengthened.

在第一实施方案中,黑基底层17被设计具有6μm的宽度。 In the first embodiment, the black base layer 17 is designed to have a width of 6μm. 然而应该注意到,黑基底层17的宽度并不限于6μm。 It should be noted, however, width of the black base layer 17 is not limited to 6μm. 黑基底层17的宽度可以设计成大于等于6μm。 Width of the black base layer 17 may be designed to be greater than or equal to 6μm. 如果黑基底层17的宽度小于6μm,很多光将在数据线24处被反射,结果,在明亮的环境下很难看到液晶显示器件10的屏幕上显示的图像。 If the width of the black base layer 17 is less than 6 m, a lot of light will be reflected at the data line 24, results in a bright environment is difficult to see the image displayed on the screen 10 of the liquid crystal display device.

公共电极26可以使用与构成覆盖液晶显示器件10端部的层的材料相同的材料构成。 The common electrode 26 may be configured to use the same material as the cover layer 10 constituting the end portion of the liquid crystal display device. 具体地,公共电极线端部可以由构成公共电极26的ITO层构成,如图8所示的接触孔39a。 Specifically, the common electrode line may be constituted by an end portion of the ITO layer constituting the common electrode 26, the contact hole shown in FIG. 8 39a. 类似地,扫描线端部和数据线端部两者都可以由构成公共电极26的ITO层构成。 Similarly both ends, the ends of the scanning lines and the data lines are made of ITO layer constituting the common electrode 26.

其结果是,公共电极26可以与液晶显示器件10的端部同时形成,并且由构成端部的材料构成。 As a result, the common electrode 26 may be formed simultaneously with the end 10 of the liquid crystal display device, and made of a material of the end portion. 这防止了形成公共电极26时的步骤数的增加。 This prevents an increase in the number of steps of forming the common electrode 26.

在液晶显示器件10中,如果公共电极26没有完全与数据线24重叠,则公共电极26将不能屏蔽与数据线24相关的电场。 In the liquid crystal display device 10, if the common electrode 26 is not completely overlap with the data line 24, the common electrode 26 can not shield the electric field associated with the data line 24. 结果,将在公共电极26和像素电极27之间产生电场,造成液晶分子的故障。 As a result, an electric field generated between the common electrode 26 and pixel electrode 27, resulting in failure of the liquid crystal molecules. 特别是,液晶分子不能按照公共电极26和像素电极27之间的电压差运转,造成垂直串扰。 In particular, the liquid crystal molecules can not follow the voltage difference between the common electrode 26 and the pixel electrode 27 operation, vertical crosstalk caused.

如果对置基板12被设计成包括黑基底层17,并且该黑基底层17具有足够大的宽度,液晶分子发生故障的区域可能会给观察者造成影响。 If the counter substrate 12 is designed to include a black base layer 17, and the black base layer 17 has a sufficiently large width, the area of ​​the liquid crystal molecules could have failed viewer impact. 相反,如果黑基底层17没有与数据线24重叠,借助在数据线24下面形成的与公共电极26电连接的不透光层,液晶分子发生故障的区域可能给观察者造成影响,从而屏蔽了从背光器件发出的光。 Conversely, if the black base layer 17 does not overlap with the data line 24, by means of opaque layer electrically connected to the common electrode 26 is formed on the data line 24 below the region of the liquid crystal molecules failure may affect to the observer, so that the shield light emitted from the backlight device. 如果不透光层没有与公共电极26电连接,不透光层将带有不稳定的电压,结果在公共电极26和像素电极27之间产生DC电场,即发生诸如串扰的故障。 If the opaque layer is not electrically connected to the common electrode 26, the opaque layer having an unstable voltage, resulting in the DC electric field between the common electrode 26 and pixel electrode 27, i.e., a failure such as crosstalk.

特别是,上述这种不透光层由构成扫描线28的第一金属层构成,并且与公共电极线26a电连接。 In particular, this above-described opaque layer is composed of a first metal layer of the scanning lines 28, and electrically connected to the common electrode line 26a. 由于公共电极线26a和26b通过接触孔39a与公共电极26电连接,则该公共电极线26a和26b可以用作不透光层。 Since the common electrode lines 26a and 26b are electrically connected via a contact hole 39a and the common electrode 26, the common electrode lines 26a and 26b may be used as the opaque layer.

上述不透光层可以由单层的铬、钛、钼、钨或者铝形成,或者也可以设计成包含这些金属层的多层结构。 The above-described layers may be opaque, titanium, molybdenum, tungsten, chromium or aluminum is formed by a single layer, or may be a multilayer structure designed to contain these metal layers. 具有多层结构的不透光层可以降低阻抗。 Opaque layer having a multilayer structure can reduce the resistance.

参考图4,在数据线24和扫描线28交叉点处及其周围区域,公共电极26不与数据线24重叠。 Referring to Figure 4, at the intersections of the data lines 28 and the scanning line 24 and its surrounding area, the common electrode 26 does not overlap with the data line 24. 因此,公共电极26不能屏蔽在数据线24和扫描线28交叉点处源于数据线24的电场。 Thus, the common electrode 26 is not shielded at the intersections of the data lines 28 and the scanning line 24 from line 24 of field data. 结果,在该交叉点和其周围的区域处将会产生电场,液晶层13中的液晶分子的运转将不正常。 As a result, an electric field will be generated at the intersection at which and the surrounding area, the operation of the liquid crystal molecules in the liquid crystal layer 13 is not normal. 此外,由于来自数据线28的电场,将使得液晶分子不能正常运转。 Further, since the electric field from data line 28, the liquid crystal molecules will not operate normally.

然而,由于公共电极26a和26b是由同样构成扫描线的第一金属层形成的,所以公共电极26a和26b不可能屏蔽液晶分子不能正常运转的上述交叉点及其周围区域。 However, since the common electrodes 26a and 26b are formed from the same metal layer constituting a first scanning line, the common electrodes 26a and 26b can not shield the intersection points and the peripheral region of the liquid crystal molecules can not operate normally.

因此,优选的是这些交叉点和区域用黑基底层17屏蔽。 Accordingly, it is preferable that the intersection area and the base layer 17 with a black mask.

图13示出了一个实例,其中黑基底层17屏蔽了交叉点和这些区域。 FIG 13 shows an example in which the black base layer 17 and the shield of the intersection of these regions. 如图13所示,在由粗实线包围的区域中形成的黑基底层17覆盖了扫描线28及其周围的区域、并覆盖了扫描线28和像素电极27之间的空间及其周围的区域,从而屏蔽光线。 As shown in FIG 13, a black base layer formed in a region surrounded by a thick solid line in the region 17 covers the scanning line 28 and around, and covers the space between the scanning lines 27 and the pixel electrode 28 and its surrounding region, thereby shielding the light.

根据第一实施方案的液晶显示器件10中的公共电极26由ITO构成,它是透明材料中的一种。 The common electrode 10 of the liquid crystal display device 26 of the first embodiment is constituted by ITO, which is a transparent material. 这样保证了在液晶显示器件10中增加透明区域,结果增加了液晶显示器件10中的开孔率。 This ensures that the liquid crystal display device 10 adds a transparent area, resulting in an increase in the opening ratio of the liquid crystal display device 10.

虽然ITO膜具备了相当高的表面电阻,具体地大约为每个单位面积100欧姆,但是,通过在每个像素中将ITO膜与公共电极线26a和26b电连接,并将由ITO膜构成的公共电极彼此电连接,有可能从整体上降低公共电极26中的电阻并防止公共电极26的冗余。 Although the ITO film have a very high surface resistance, particularly from about 100 ohms per unit area, but the ITO film through the common electrode and the common lines 26a and 26b will be electrically connected to each pixel, and constituted of an ITO film electrodes electrically connected to each other, it is possible to reduce the resistance of the common electrode 26 as a whole and the common electrode 26 to prevent redundancy.

根据图5可以理解,第二夹层绝缘膜25夹在公共电极26和数据线24之间。 It is understood from FIG. 5, a second interlayer insulating film 25 is sandwiched between the common electrode 26 and the data line 24. 通过把第二夹层绝缘膜设计成具有高比率d/ε,其中“d”代表第二夹层绝缘膜25的厚度,“ε”代表介电常数,有可能降低在数据线24和公共电极26之间形成的寄生电容。 By the second interlayer insulating film is designed to have a high ratio of d / ε, where "d" represents the thickness of the second interlayer insulating film 25, "ε" representative of the dielectric constant, it is possible to decrease the data line 24 and the common electrode 26 of formed between the parasitic capacitance.

此外,由于上述串扰问题得到解决,所以不再需要用于防止由从数据线24泄露的电场而导致的在显示图像时出现降级现象而形成的黑基底层17。 Further, since the crosstalk problem is resolved, there is no need for a leakage electric field from data line 24 leading to degraded phenomenon occurs when a display image formed by the black base layer 17 prevented. 因此,黑基底层17的形成只为大的改进而形成,确保黑基底层17可以具有降低的宽度。 Accordingly, only a black base layer 17 is formed to be large improvements, ensures that the black base layer 17 may have a reduced width. 降低黑基底层17的宽度可以保证液晶显示器件10中开孔率的增加。 Reducing the width of the black base layer 17 may be increased to ensure that the opening 10 of the liquid crystal display device.

在液晶显示器件10中,公共电极26和像素电极17两者都形成在第二夹层绝缘膜25上。 In the liquid crystal display device 10, both of the common electrode 26 and the pixel electrode 17 is formed on the second interlayer insulating film 25. 通过在相同的层上一起形成公共电极26和像素电极17,有可能在相同的步骤中形成公共电极26和像素电极17,并且由相同的材料制成,确保生产成品率的提高。 26 and the pixel electrode 17, the pixel electrodes 26 and 17 is possible by forming a common electrode formed on the same layer together in the same step in the common electrode, and made of the same material, to ensure increased production yield.

如前所述,在液晶显示器件10中,屏蔽数据线24的公共电极26由ITO构成。 As described above, in the liquid crystal display device 10, the shield common electrode 26 is composed of the data lines 24 of ITO. 与使用ITO以外的金属构成的公共电极26相比,使用ITO构成的公共电极26,有可能增强液晶显示器件10的可靠性。 Compared to common electrode common electrode 26, the use of ITO and a metal other than the use of ITO constituting 26, it is possible to enhance the reliability of the liquid crystal display device 10. 其原因将在后面说明。 The reason for this will be explained later.

如图14所述,假定公共电极26和像素电极27两者都是由ITO以外的金属制成,它们形成在第二夹层绝缘膜25上,并且厚度在500到1000埃的定向膜31也形成在第二夹层绝缘膜25上,覆盖了公共电极16和像素电极27。 As shown in Figure 14, assuming that both the common electrode 26 and the pixel electrode 27 is made of a metal other than ITO, are formed on the second interlayer insulating film 25, and the thickness 31 is also formed in the alignment film 500 to 1000 angstroms on the second interlayer insulating film 25, 16 covering the common electrode and the pixel electrode 27.

如果定向膜31带有针孔32,构成液晶层13的液晶材料和构成公共电极26和像素电极27的金属都将彼此产生电化学反应,结果构成公共电极16和像素电极27的金属可能被作为金属离子33洗提到液晶层13中。 If the alignment film 31 with a pinhole 32, the liquid crystal material constituting the liquid crystal layer 13 and the common electrode 26 and the metal constituting the pixel electrode 27 to each other will produce an electrochemical reaction, the metal constituting the result of the common electrode 16 and the pixel electrode 27 may be as 33 mentioned metal ions in the wash liquid crystal layer 13. 如此将金属离子33洗提到液晶层13将造成显示图像时的不均衡。 Thus the metal ion is not eluted into 33 of the liquid crystal layer 13 when the equilibrium will result in the display image.

特别是,当液晶层13由具有强极性的液晶材料构成时,金属离子33将侵入性地被洗提到液晶层13中。 In particular, when the liquid crystal layer 13 is composed of a liquid crystal material having a strong polarity, the metal ions 33 is eluted invasively the liquid crystal layer 13. 由于需要在平面开关模式液晶显示器件中形成具有高介电常数各向异性Δε材料的液晶层13,所以金属离子33将侵入性地被洗提到液晶层13中。 Since the liquid crystal layer needs to be formed having a high dielectric anisotropy Δε material in-plane switching mode liquid crystal display device 13, the metal ions 33 will be eluted invasively the liquid crystal layer 13.

因此,均与定向膜31接触的公共电极26和像素电极27优选地由不会与液晶材料产生电化学反应的材料制成,即,这种材料与液晶材料几乎不发生反应。 Thus, both the orientation film 31 in contact with the common electrode 26 and the pixel electrode 27 is preferably a material that does not produce an electrochemical reaction with the liquid crystal material, i.e., the liquid crystal material with such a material hardly react.

十分明显,事实是TN(扭曲向列)或者STN(超扭曲向列)型的液晶显示器件中的透明电极经常是由ITO材料制成的,ITO在电化学反应中是十分稳定的,例如在上述情况下。 Very clear, the fact that a TN (Twisted Nematic) or STN (super twisted nematic) type liquid crystal display device a transparent electrode of an ITO material is often made of ITO in the electrochemical reaction is very stable, e.g. under the above circumstances.

因此,由ITO形成的公共电极26和像素电极27两者都可以直接与定向膜31的接触,与使用ITO以外材料的公共电极和像素电极形成的液晶显示器件相比,保证了液晶显示器件10可靠性得到提高。 Therefore, as compared both the common electrode 26 is formed of ITO and the pixel electrode 27 may be in direct contact with the alignment film 31, a common electrode and the pixel electrode using a material other than ITO, a liquid crystal display device, a liquid crystal display device 10 to ensure that the improved reliability.

下面根据第一实施方案详细说明液晶显示器件10。 The following detailed description of the liquid crystal display device 10 according to the first embodiment. 此外,还将在下面说明液晶显示器件10的各种变形方式。 Further, various modifications will be described below in the liquid crystal display device 10.

在液晶显示器件10中,在液晶显示器件10中几乎所有区域中,公共电极26完全被数据线24重叠。 In the liquid crystal display device 10, in almost all regions of the liquid crystal display device 10, the common electrode 26 completely overlaps the data line 24. 优选的是,公共电极26在其对置边、沿横向方向上延伸的部分延伸超出数据线241.5μm或者更大。 Preferably, the common electrode 26 opposite sides thereof, the lateral extending portion extending beyond the data line at 241.5μm or greater.

发明人已经进行了实验,发现在公共电极26沿横向延伸超出数据线24边缘延伸部分的长度Le[μm]、第二夹层绝缘膜25的厚度“d”、以及穿过数据线24一侧的光线行程(light passage)之间的关系。 The inventors have conducted experiments and found along the common electrode 26 extends laterally beyond the edge 24 extending the length of the portion of the data line Le [μm], a second interlayer insulating film 25 of a thickness "d", and the data line 24 side through the the relationship between the stroke of light (light passage).

图15是发明人进行实验的液晶显示器件的剖面图。 FIG 15 is a sectional view of the liquid crystal display device of the experiments conducted by the inventors. 实验条件如下:液晶的介电常数各向异性Δε=8液晶的折射系数=0.067液晶层13的厚度=4.5μm公共电极26的光透射率=100%(透明)数据线24的光透射率=0%(不透明)公共电极26和像素电极27之间的距离=10μm第二夹层绝缘膜25的介电常数=ε第二夹层绝缘膜25的厚度“d”=0.5、1.0和2.0μm在上述条件下,实验是在屏幕是在带有黑色背景的白色窗口中显示黑色时进行的。 Experimental conditions were as follows: the dielectric anisotropy of the liquid crystal Delta] [epsilon = refractive index of the liquid crystal 8 = 0.067 The thickness of the liquid crystal layer 13 = 4.5 m light transmittance of the common electrode 26 = 100% (transparent) the light transmittance of the data line 24 = 0% of the distance between the pixel electrodes 26 and 27 (opaque) 10 m = common electrode second interlayer insulating film [epsilon] = dielectric constant of the second interlayer insulating film 25 of a thickness "d" 25 = 0.5, 1.0 and 2.0μm in the above-described under the condition, experiments were carried out when the screen is displayed in black on white with a black background of the window. 图16示出了在该实验中,由于在周围的白色显示,从数据线24泄露电场造成的光线行程。 FIG 16 illustrates this experiment, since the display around the white light stroke caused by leakage electric field from data line 24. 图16中的光线行程是将光的透射率对与像素相关的宽度进行积分而计算出的,如图15所示。 Light travel 16 is the transmittance of light relative to the pixel width is calculated by integrating, as shown in FIG.

尽管在显示黑色时光的透射率等于0.0,但是,由于从数据线24泄露的电场,它还是有一定的值自。 Although the transmittance of black display time is equal to 0.0, but, due to the electric field from the data line 24 leaks, it still has some value from. 正如图16所示,延伸部分Le[μm]越大,光线行程越小。 As shown in Figure 16, the extension portion Le [μm], the smaller the light travel. 这不取决于第二夹层绝缘膜25的厚度“d”。 It does not depend on the thickness of the second interlayer insulating film "d" 25's.

另一方面,在白色显示中的光线行程是通过将白色显示时的光透射率对与像素相关的宽度进行积分而进行计算的。 On the other hand, light rays travel in the white display is performed by calculating the light transmittance during white display pixel width associated with integrating. 特别是,在白色显示时,光线行程的计算结果等于12。 In particular, when white display, the calculation result is equal to the stroke of the light 12. 在数据线24一侧通过的最大容许光线行程应该小于等于在屏幕显示白色时得到像素中光线行程的1/100。 The maximum allowable stroke ray data line 24 side through the pixel should be obtained in less light travel 1/100 of a white display when the screen. 因此,图16中的光线行程必须小于等于0.12。 Thus, light rays 16 must travel less than or equal 0.12.

在图16中,当光线行程等于0.12时,公共电极26的延伸部分Le[μm]可以当作大约1.5μm。 In FIG. 16, when a light stroke is equal to 0.12, the extended portion of the common electrode 26 Le [μm] can be used as about 1.5μm. 因此,有可能通过将公共电极26的延伸部分Le[μm]定为1.5μm,来减少从数据线24一侧通过的最大容许光线行程。 Thus, it is possible by extending the portion of the common electrode 26 Le [μm] as 1.5 m, to reduce the maximum allowable stroke ray through the data line 24 side.

在第一实施方案中,液晶显示器件10被设计成包括了与彩色层18分开的黑基底层17。 In the first embodiment, the liquid crystal display device 10 is designed to include 18 separate from the black color layer 17 the base layer. 然而,应该注意到,黑基底层17可以由多个彩色层18的多层结构所替代。 However, it should be noted that the black base layer 17 may be replaced by a multilayer structure of a plurality of color layers 18.

参考图17,红色层18a、绿色层18b和兰色层18c设计成部分彼此重叠。 17, a red layer 18a, a green layer and a blue layer 18b 18c designed to partially overlap each other. 在彼此部分重叠的彩色层18a到18c处的彩色层18a到18c的部分具有与黑基底层17相同的功能。 Having the same function as the base layer 17 in the black portion of the colored layers overlap each other colored layers 18a to 18c at 18a through 18c.

不需要通过设计彩色层18a到18c部分相互重叠的方法来形成黑基底层17。18a到18c的红、绿、兰层可以这样形成,通过改变18a到18c彩色层的图案实现它们的彼此重叠。 A black base layer need not be formed 17.18a 18c to red, green and blue layers can be formed by this method 18a to 18c partially overlapping color layers design, they overlap each other by changing the color pattern layers 18a to 18c. 由于改变18a到18c彩色层的图案的工作量小于形成黑基底层17的工作量,所以,彩色层18a到18c的多层结构将增强液晶显示器件10的成品率。 Due to changes in the workload of the color pattern layers 18a to 18c is smaller than the base layer 17 is formed of black work, therefore, the color layers 18a to 18c of the multilayer structure will enhance the yield of the liquid crystal display device 10.

为了代替上述的三层彩色层,可以用红、绿、兰中的任何两种颜色的彩色层彼此层叠,以替代黑基底层17。 In place of the above-described three-color layer, with the red, green and blue color in any two color layers laminated with each other, instead of a black base layer 17.

在液晶显示器件10中,像素辅助电极35、在数据线24延伸方向上定义的每个柱的上下端的公共电极线26a和公共电极线26b,可以被设计成如图18所示具有这样的倾斜边缘,如果液晶定向的方向在图18所示的由像素电极27和公共电极26包围的整个显示区域上全部以某个锐角沿顺时针方向旋转,使得在通过摩擦确定的摩擦方向或液晶的定向方向、以及在像素电极27(和与像素电极27施加相同电压的像素辅助电极35)施和公共电极26(和与公共电极26施加相同电压的公共电极线26a和26b)之间施加的电场的方向之间的关系被确定,保证了该液晶定向的方向与该电场的方向重叠。 In the liquid crystal display device 10, an auxiliary pixel electrode 35, the common electrode line upper and lower ends of each post 24 is defined in the extending direction of the data line 26a and the common electrode line 26b, may be designed as shown in Figure 18 has an inclined edge, over the whole display area of ​​the pixel electrode 27 and the common electrode 26 surround the oriented direction if the liquid crystal shown in Fig. 18 all in an acute angle in the clockwise direction, so that the liquid crystal is oriented in the rubbing direction is determined by the friction direction, and at 27 (the auxiliary electrode and the pixel same voltage is applied to the pixel electrode 2735) is applied between the common electrode 26 and the applied (and the same voltage is applied to the common electrode 26 and the common electrode lines 26a and 26b) of the pixel electrode electric field the relationship between the directions is determined to ensure that the direction of the liquid crystal alignment direction of the electric field overlaps.

如果有一个区域,其中液晶定向方向是通过沿反时针方向以某个锐角旋转液晶定向方向而与电场的方向重叠,则这个区域将会在像素一端产生域,其中当电场施加到像素电极27和公共电极26上时,液晶以与所希望的方向相反的方向旋转。 If there is a region in which the liquid crystal alignment direction of the liquid crystal alignment direction of rotation is at an acute angle to a counterclockwise direction by the direction of overlap of the electric field, the field is generated in this region will end pixel, wherein when an electric field is applied to the pixel electrode 27 and the when the common electrode 26, with the desired rotation direction opposite to the liquid crystal. 如果存在上述域,并且在上述液晶分子按照希望方向旋转的域和液晶分子按照与所希望的方向相反的方向旋转之间的域的边界处长时间地发生旋转位移,则显示质量将会降低,并且与初始条件相同的条件将不能经常得到,结果液晶显示器件的可靠性会降低。 If the above fields, and between the liquid crystal molecules rotate in accordance with the desired direction of liquid crystal molecules and domain rotation in the opposite direction to the desired boundary of the field at such time as disclination is present, then the display quality will be reduced, and the same conditions as the initial conditions can not always be obtained, the reliability of the results of the liquid crystal display device may be reduced.

液晶分子的这种反向旋转也是可以预防的,方法是将像素辅助电极35和公共电极26a和26b设计成具有倾斜的边缘,如图18所示。 This is the reverse rotation of the liquid crystal molecules can be prevented, the pixel is the auxiliary electrode 35 and the common electrode 26a and 26b are designed to have an inclined edge, as shown in Fig. 因此,在本说明书中,通过将设计成带有倾斜边缘的像素辅助电极35和公共电极26a和26b,使得液晶分子仅仅按照单一的方向扭转的结构被称作反向旋转阻止结构。 Accordingly, in the present specification, by the design into pixels having oblique edge 35 of the auxiliary electrode and the common electrode 26a and 26b, so that only the liquid crystal molecules twisted structure in accordance with a single direction is called reverse rotation inhibiting structure.

下面将说明在液晶显示器件10中反向旋转阻止结构36的层状结构。 It will be described below to prevent the reverse rotation of the structure 36 in the layered structure of the liquid crystal display device 10.

在图19A中,第一金属层是由带有狭窄空间的倾斜的延伸线示出的成,第二金属层是由带有较宽空间的倾斜的延伸线示出的。 In FIG 19A, the first metal layer is shown by oblique lines extending into a narrow space with the second metal layer is composed of an extension line sloped with wider spaces shown. 扫描线28和公共电极线26a和26b由第一金属层构成,同时,数据线24和像素辅助电极35由第二金属层构成。 Scanning lines 28 and the common electrode lines 26a and 26b is constituted by a first metal layer, while an auxiliary data line and the pixel electrode 24 is made of a second metal layer 35.

图19B示出了由ITO构成的各层。 FIG 19B shows the respective layers made of ITO. 公共电极26和像素电极27都由ITO构成。 The common electrode 26 and the pixel electrode 27 constituted by ITO. 如图18中示出的反向旋转阻止结构36可以是这样制作成的:在如图19A示出的各层上,用被夹在其间的夹层绝缘膜与如图19B所示的各层重叠。 The reverse rotation preventing structure 18 shown in FIG. 36 may be made to this: On the layers shown in FIG. 19A, as shown by the overlapping layers sandwiched therebetween an interlayer insulating film 19B and FIG. .

通过防止液晶分子的分子轴反向旋转,液晶显示器件10具有改进了的显示质量和可靠性。 Molecular axis of the liquid crystal molecules by preventing reverse rotation of the liquid crystal display device 10 having improved display quality and reliability. 例如,诸如使用液晶显示器件10的个人计算机等类似的电子器件,可以通过采用该反向旋转阻止结构36防止显示质量的退化。 For example, a liquid crystal display device such as a personal computer similar to electronic device 10, by using the reverse rotation preventing structure 36 prevent degradation of display quality.

例如,日本专利号2973934(日本待审专利出版号10-26767)已经提出了一个反向旋转阻止结构的实例。 For example, Japanese Patent No. 2973934 (Japanese Unexamined Patent Publication No. 10-26767) has proposed an example of a reverse rotation preventing structure.

如图20所示,液晶显示器件10可以设计成包括在第二夹层绝缘膜25上形成的钝化膜37,其覆盖上述公共电极26和像素电极27。 20, the liquid crystal display device 10 may be designed to include a passivation film formed on the second interlayer insulating film 2537 covering the pixel electrode 26 and the common electrode 27. 定向膜31形成在钝化膜37上。 An orientation film 31 is formed on the passivation film 37.

如图21所示,如果强电场长时间地施加在公共电极26和像素电极27上,将在公共电极26和像素电极27彼此相对的边缘处发生液晶的误定向,结果造成显示缺陷。 Display defects if a strong electric field is applied for a long time in the common electrode 26 misdirected and 27, the liquid crystal will occur and the common electrode 26 opposite to each other at the edge of the pixel electrode of the pixel electrode 27, resulting in 21 as shown in FIG.

图20示出了将会减弱在公共电极26和像素电极27的边缘处产生的强电场的钝化膜37,从而避免了液晶分子的误定向和显示缺陷。 Figure 20 shows a passivation film will be weakened in the strong electric field generated at the edge of the common electrode 26 and the electrode 27 of the pixel 37, thereby avoiding erroneous orientation of the liquid crystal molecules and the display defect.

液晶显示器件10(参阅图22)中的接触孔39具有边长6μm的方形截面。 The liquid crystal display device 10 (see FIG. 22) in the contact hole 39 having a square cross-section side length of 6μm. 但是,其边长并不限于6μm,也可以大于6μm。 However, it is not limited to the side length of 6 m, it may be larger than 6μm.

此外,接触孔39可以设计成矩形截面,这时接触孔39的短边应该大于等于6μm。 Further, the contact hole 39 may be designed as a rectangular cross-section, then the contact hole 39 is short side should be not less than 6μm.

根据发明人进行的实验,如果接触孔39的边长或者短边小于6μm,在穿过接触孔39的上、下层之间适当的电连接将不能得到保证。 According to experiments conducted by the inventors, if the contact hole 39 side or a short side of less than 6 m long, through the contact hole 39 in the proper electrical connection between the lower layer can not be guaranteed.

如图22所示,接触孔39可以用金属膜29覆盖。 22, the contact hole 39 may be covered with a metal film 29. 接触孔39还可以设计成带锥形的内壁,在这种情况下,接触孔39顶部的尺寸为6μm×6μm。 The contact hole 39 may also be designed with a conical inner wall, in this case, the size of the top of the contact hole 39 is 6μm × 6μm. 接触孔39可以与公共电极线26a和26b接触。 The contact hole 39 may be in contact with the common electrode lines 26a and 26b. 如图22中示出的接触孔和图8中示出的接触孔39a和39b的内壁上都覆盖了金属膜29,并且金属膜29被与公共电极26电连接的ITO膜46覆盖(参阅图8)。 As shown in the contact holes 22 and 8 shown on the inner wall of the contact holes 39a and 39b shown are covered metal film 29, the ITO film and the metal film 29 is electrically connected to the common electrode 26 to cover 46 (see FIG. 8).

通过在接触孔的内壁上使用金属膜29覆盖接触孔39,将可以减少作为透明电极形成的公共电极26和公共电极线26a及26b之间的阻抗,增强图像显示时的均衡性。 Cover the contact holes 39 through 29, it will reduce the impedance between the common electrode 26 and the common electrode lines 26a and 26b is formed as a transparent electrode, to enhance the balance between image display time of a metal film on the inner wall of the contact hole.

液晶显示器件10中的第二夹层绝缘膜25的厚度例如在1μm到2μm的范围。 The thickness of the second interlayer insulating film 10, the liquid crystal display device 25, for example, in the range of 1μm to 2μm.

如前所述,第一实施方案中的第二夹层绝缘膜25被设计成由第一膜25a和第二膜26b制成。 As described above, in the first embodiment of the second interlayer insulating film 25 is designed to be made of a first film 25a and a second film 26b. 如图9所示,作为一种替代方法,第二夹层绝缘膜25可以设计成由无机或有机材料制成的单层构成。 9, as an alternative, the second interlayer insulating film 25 may be designed as a single layer made of an inorganic or organic material. 图9示出的第二夹层绝缘膜25只是由无机材料制成的第一膜构成。 Second interlayer insulating film 25 shown in FIG. 9 only the first film is made of an inorganic material. 如图8所示,作为一种替代方法,第二夹层绝缘膜25可以设计成由无机材料制成的第一膜、和覆盖了上述第一膜并由有机材料制成的第二膜组成。 As shown, as an alternative, the second interlayer insulating film 25 may be designed into a first film made of an inorganic material, and the cover 8 of the first film by a second film made of an organic material.

由于有机膜的介电常数小于无机膜,与由单层无机膜构成的夹层绝缘膜相比,上述包含第一和第二膜的多层结构其将减小夹层绝缘膜的介电常数。 Since the dielectric constant is smaller than the organic film an inorganic film, as compared with the interlayer insulating film composed of an inorganic film of a single layer, the above-described multi-layer structure comprising a first and a second film which will reduce the dielectric constant of the interlayer insulating film.

如果夹层绝缘膜由单层有机膜构成,则在TFT中的半导体层和覆盖上述半导体层的有机膜之间的界面将是不稳定的,在这种情况下,如果TFT在高温下运行,TFT的泄露电流将增加,结果造成显示的均衡性差。 If the interlayer insulating film of a single layer organic film, the interface between the semiconductor layer of the TFT and the organic film covering the semiconductor layer would be unstable, in which case, if the TFT operate at high temperatures, TFT leakage current will increase, resulting in poor balance display. 通过将与TFT的半导体层接触的第一膜设计成由诸如氮化硅膜等的无机膜构成,并且在第一膜上形成有机层,将使无机膜和半导体层之间的界面稳定,从而保证上述问题得到解决。 And the organic layer is formed by a first film is designed to be in contact with the TFT semiconductor layer made of an inorganic film such as silicon nitride film, the first film will make the interfacial stability between the inorganic film and the semiconductor layer, ensure that the above issues are resolved.

无机膜和有机膜的实例见表1。 Examples of the inorganic film and the organic film are shown in Table 1.

如表1所示,当第二夹层绝缘膜25由单层无机膜制成时,该无机膜可以选自氮化硅(SiNx)膜、无机聚硅氮烷膜、多层结构的氮化硅膜和氧化硅膜、多层结构的氮化硅膜和无机聚硅氮烷膜等。 Silicon nitride as shown in Table 1, when the second interlayer insulating film 25 is made of single-layer inorganic film, the film may be selected from inorganic silicon nitride (SiNx) film, an inorganic polysilazane film, a multilayer structure film and a silicon oxide film, a silicon nitride film having a multilayer structure and an inorganic polysilazane film.

当第二夹层绝缘膜25由单层有机膜制成时,该有机膜可以选自苯并环丁烯(BCB)膜、有机聚硅氮烷膜或者硅氧烷膜等。 When the second interlayer insulating film 25 is made of single-layer organic film, the organic film may be selected from a benzocyclobutene (BCB) film, an organic polysilazane film or silicone film.

当第二夹层绝缘膜25设计成具有第一和第二膜的多层结构时,第一膜可以选自氮化硅膜,同时第二膜可以选自光敏丙烯酸树脂膜或者光敏聚酰亚胺树脂膜。 When the second interlayer insulating film 25 having a multilayer structure designed to first and second films, the first film may be selected from a silicon nitride film, while the second film may be selected from a photosensitive acrylic resin film or a photosensitive polyimide a resin film.

虽然表1指出在多层结构中无机膜的厚度是0.15μm,但是在该多层结构中的无机膜的厚度不限于0.15μm。 While Table 1 indicates the thickness of the multilayer structure of the inorganic film is 0.15μm, but the thickness of the inorganic film in the multilayer structure is not limited to 0.15μm. 该多层结构中的无机膜可以设计成厚度范围在0.1μm到1.0μm之内(含端值)。 The multilayer structure of the inorganic film may be designed to a thickness in the range of 0.1μm to 1.0μm (inclusive).

即使在数据线24和由与数据线24重叠的透明电极制成的公共电极26之间,由有机膜构成的第二膜有针孔,但通过将该无机膜的厚度设计成大于等于0.25μm,就可以使得作为第一膜的无机膜具备足够高的击穿电压,从而就可以在液晶板制成后或者显示图像时,防止数据线24和与数据线24重叠的公共电极26由于夹层绝缘膜的介电击穿二彼此短路,进而显著降低了由于在数据线24和公共电极26之间的上述短路造成的数据线24的缺陷。 Even between the data lines 24 and 26 by the common electrode and the transparent electrode 24 is formed overlapping the data line, the second film is an organic film composed of pinholes, but by the thickness of the inorganic film is designed to be greater than or equal to 0.25μm , can be used as the inorganic film such that the first film have a sufficiently high breakdown voltage, so that it can be made when the liquid crystal panel or the display image, since the interlayer insulation 26 to prevent overlap of the data line 24 and data line 24 and the common electrode breakdown of the dielectric film two short-circuited to each other, and thus significantly reduces defects due to the short-circuit between the data line 24 and the common electrode 26 due to the data line 24.

应该指出,表1显示的各膜的厚度仅仅是示意性的,不应局限于这些具体的厚度上。 It should be noted that the thickness of each film are shown in Table 1 are merely illustrative and should not be limited to these specific thickness.

如图23所示,根据第一实施方案的液晶显示器件10,形成在第二夹层绝缘膜25上的公共电极26可以设计成与扫描线28重叠,并且在扫描线28和公共电极线26a和26b之间留有空间。 23, the liquid crystal display device 10 of the first embodiment, a common electrode formed on the second interlayer insulating film 25, 26 can be designed to overlap with the scanning line 28, and the scanning line 28 and the common electrode line 26a and the leave space between 26b. 采用这种结构的公共电极26可以屏蔽扫描线28泄露的电场,保证由在像素电极27和公共电极26上施加的电场进行控制的有效显示区域得到增加,并且提高了液晶显示器件10的开孔率。 With such a structure of the common electrode 26 can shield the leakage field scanning line 28, to ensure the effective control of the display region of the pixel electrode 27 and the electric field applied to the common electrode 26 is increased, and increases the aperture of the liquid crystal display device 10 rate.

类似地,公共电极26可以设计成与TFT30的沟道沟道区重叠。 Similarly, the common electrode 26 may be designed to overlap with the channel of the channel region TFT30. 具备这种结构的公共电极26可以防止外部的电场进入TFT30,保证TFT特性的稳定性和显示图像的可靠性得到加强。 The common electrode 26 having such a configuration of the external electric field can be prevented from entering the TFT 30, the TFT characteristics to ensure the reliability and stability of the display image is strengthened.

如图24所示,在借助像素的平面图观察时,公共电极线26a可以在每个像素的下边缘附近形成。 24, when viewed in plan by the pixel, the common electrode line 26a may be formed in the vicinity of the lower edge of each pixel. 这就是说公共电极线26a可以在紧邻扫描线28的上面定位。 This means that the common electrode lines 26a may be positioned immediately above the scan line 28.

由于公共电极26由透明材料制成,所以透明区域将因为有公共电极26占据的区域而增加,确保了液晶显示器件10开孔率的提高。 Since the common electrode 26 is made of a transparent material, the transparent regions because the area occupied by the common electrode 26 is increased to ensure improved opening 10 of the liquid crystal display device.

作为替代方案,如图25所示,当借助像素的平面进行观察时,公共电极线26a可以在每个像素的下边缘附近形成,而公共电极线26b可以在每个像素的上边缘附近形成。 Alternatively, as shown in FIG 25, when viewed by a pixel plane, the common electrode line 26a may be formed in the vicinity of the lower edge of each pixel and the common electrode line 26b may be formed in the vicinity of the upper edge of each pixel. 通过在每个像素中的上边缘和下边缘附近形成公共电极线26a和26b,与在每个像素的上或下边缘附近形成公共电极线26a和26b之一比较,将可以增加存储容量。 Forming the common electrode lines 26a and 26b through the vicinity of the upper and lower edges in each pixel, the common electrode lines 26a and a comparator 26b formed in the vicinity of one of each of the pixels of the upper or lower edge of the storage capacity can be increased.

当通过像素的平面图观察时,在TFT30被定位在每个像素的下半部分的液晶显示器件中,例如根据第一实施方案的液晶显示器件10,当从像素的平面图观察时,像素电极27和定义了漏极30a的漏层可以通过在每个像素下边缘附近的接触孔39b彼此电连接,并且公共电极26和公共电极线26b可以通过在每个像素上边缘附近的接触孔39a彼此电连接,如图26所示。 When viewed in plan by the pixel, the TFT30 is positioned in the lower half of the liquid crystal display device of each sub-pixel, for example, a liquid crystal display device according to a first embodiment 10 of the embodiment, when viewed from a plan view of a pixel, the pixel electrode 27 and the defines a drain layer 30a can drain through the contact hole 39b near the edge of the electrically connected to each other in each pixel, and the common electrode 26 and the common electrode line through the contact hole 26b near the edge 39a on each pixel electrically connected to each , shown in Figure 26.

当通过像素的平面图观察时,在TFT30被定位在每个像素的上半部分的液晶显示器件中,与液晶显示器件10相反,当从像素的平面图观察时,像素电极27和定义了漏极30a的漏层可以通过在每个像素上边缘附近的接触孔39b彼此电连接,而公共电极26和公共电极线26b可以通过在每个像素下边缘附近的接触孔39a彼此电连接,如图27所示。 When observed through a plan view of a pixel in the TFT30 liquid crystal display device is positioned in the upper half of each pixel, 10 opposite to the liquid crystal display device, when viewed from a plan view of a pixel, the pixel electrode 27 and the drain 30a define drain layer via the contact hole 39b near the edge of the electrically connected to each other in each pixel, and the common electrode 26 and the common electrode line 26b near the edge of the contact hole 39a is electrically connected to each other at each pixel can be, as shown in FIG 27 shows.

如上所述,通过使公共电极26与公共电极线26a和26b借助在每个像素中的接触孔39a或39b彼此电连接,这有可能降低公共电极26的总阻抗。 As described above, 39a or 39b is electrically connected to the common electrode through the contact hole in each pixel 26 and the common electrode lines 26a and 26b by means of another, which may reduce the overall impedance of the common electrode 26.

由于公共电极26是由在除了在第二膜25b上形成的由透明金属膜构成的公共电极26的区域以外的区域中的第一金属层构成的,所以根据第三实施方案的平面开关模式液晶显示器件85要比根据第一实施方案的平面开关模式液晶显示器件10的开孔率低。 Since the common electrode 26 is made in a region other than the region of the common electrode formed of a transparent metal film is formed on the second film 25b is 26 in the first metal layer, so-plane switching mode according to a third embodiment of the liquid crystal rate than the liquid crystal display device 85 display device 10 according to the aperture plane switching mode of the first embodiment. 然而,因为公共电极26由不同于形成像素电极27的层的层构成,所以公共电极26和像素电极27彼此不会发生短路,保证了生产成品率的提高。 However, since the common electrode layer, layer 26 is formed by the pixel electrode 27 differs from the configuration, the common electrode 26 and the pixel electrode 27 do not short-circuited with each other, to ensure improved production yield. 第四实施方案图40和41示出了根据本发明的第四实施方案的平面开关模式液晶显示器件100。 The fourth embodiment of FIGS. 40 and 41 show a liquid crystal display device 100 according to a fourth embodiment plane switching mode embodiment of the present invention. 图40是液晶显示器件100的平面图,图41是图40沿XXXXI-XXXXI线的剖面图。 FIG 40 is a plan view of a liquid crystal display device 100, FIG. 41 FIG. 40 is a cross-sectional view along the line XXXXI-XXXXI in Fig. 在图64中,TFT区、像素区和接触孔区都是由单独的图示出的。 In FIG. 64, TFT region, the pixel region and the contact hole regions are illustrated by the individual. 并且在图40中沿线AA、XXXXI-XXXXI和CC分别示出了TFT区、像素区和接触孔区的剖面图。 And along line AA in FIG. 40, XXXXI-XXXXI and CC respectively show a cross-sectional view of a TFT region, the pixel region and the contact hole areas.

公共电极126和像素电极127两者都被设计成梳齿状,公共电极126和像素电极127中的梳齿平行向数据线124延伸。 Both the pixel electrode 126 and the common electrode 127 are designed as comb-shaped, comb-shaped common electrodes 126 and parallel to the pixel electrode 127 extends to the data line 124. 即,如图42A所示,液晶显示器件100是这样一种类型:有源器件基板111的开口111a沿数据线124延伸的方向延伸。 That is, as shown in FIG, 100 is of the type liquid crystal display device 42A: 111a extending in a direction along the data line 124 extending in an opening 111 of active device substrate.

在第四实施方案中的公共电极126和像素电极127中的梳齿被设计成之字形,不同于第一实施方案中的公共电极26和像素电极27中的梳齿。 In a fourth embodiment, the common electrode 126 and the pixel electrode 127 in comb teeth are designed in a zigzag, different from the common electrode 27 and the comb teeth of the pixel electrode 26 of the first embodiment. 公共电极126和像素电极127中的梳齿彼此啮合,并且彼此间隔开。 The common electrode 126 and the pixel electrode 127 in the comb teeth engage with each other, and are spaced apart from each other.

在平面开关模式液晶显示器件100中,在公共电极126和像素电极127之间产生的电场平行于像素中的电绝缘透明基板116和122,该像素是通过扫描线128传输的扫描信号选定的、并将通过数据线124传输的数据信号写入其中。 In-plane switching mode liquid crystal display device 100, the electric field generated between the pixel electrode 126 and the common electrodes parallel to the pixel 127 of an electrically insulating transparent substrate 116 and 122, the pixel 128 by the scan signal is transmitted to the selected scan line and writes the data in which the data signal transmission line 124. 因此,所产生的电场方向取决于公共电极126和像素电极127弯曲的方向。 Thus, the direction of the electric field produced depends on the bending direction 127 the common electrode 126 and the pixel electrode.

如图40所示,像素所占据的区域被分成第一像素子区和第二像素子区,这取决于公共电极126和像素电极127的弯曲方向,即,施加在公共电极126和像素电极127上的电场的方向。 , The pixel area occupied by the pixel in FIG 40 is divided into a first region and a second sub-pixel sub-region, depending on the bending direction of the pixel electrode 126 and the common electrode 127, i.e., applied to the common electrode 126 and the pixel electrode 127 the direction of the electric field on. 在第一和第二像素子区中,液晶分子的指向矢是沿与按照在平行于有源器件基板111表面的平面中施加的电场相反的方向旋转的,,以显示图象。 In the first and second sub-pixel region, the director of liquid crystal molecules are rotated in a direction opposite to the applied electric field according to a plane parallel to the surface of the active device 111 ,, substrate to display an image. 这就是说,根据第四实施方案的液晶显示器件100被称为多域类型。 That is, the liquid crystal display device according to a fourth embodiment 100 is referred to as multi-domain type.

在公共电极126和像素电极127上施加的电场方向是变化的,这取决于它们之间的面积。 The direction of the electric field applied across the common electrode 126 and the pixel electrode 127 is varied, depending on the area therebetween. 具体说,像素所占据的区域可以分为液晶分子的指向矢按照顺时针方向旋转的第一像素子区、和液晶分子的指向矢按照逆时针方向旋转的第二像素子区。 Specifically, the pixel area occupied by the second pixel can be divided into a first sub-pixel region director of the liquid crystal molecule director subzone rotated clockwise, and the liquid crystal molecules rotate in the counterclockwise direction. 像素子区可以称为域。 Sub-pixel region may be called a domain.

在第一和第二像素子区中,通过将液晶分子的各指向矢设计成彼此反向旋转,第一和第二像素子区可以相互得到光学补偿。 In the first and second sub-pixel region, the liquid crystal molecules by the respective directors are designed to reverse rotation to each other, the first and second sub-pixel region may be obtained optically compensate each other. 因此,可以防止图象在倾斜观看时出现色彩,并且进一步防止在黑色显示和相当黑的中等色调之间发生的降级的反转,保证了视角特性得到加强。 Thus, the color image can be prevented occur when viewed obliquely, and further prevent the display inversion and degraded considerably between the black color tone in the black medium, ensure enhanced viewing angle characteristics.

在液晶显示器件100中,公共电极126和像素电极127两者均由ITO构成,它是透明材料中的一种。 In the liquid crystal display device 100, the common electrode 126 and the pixel electrode 127 are both formed of ITO, which is a transparent material.

如图41所示,公共电极126形成在除了形成数据线124的层面之外的层面上,此外与第一实施方案类似的是,公共电极126完全与数据线124重叠。 41, the common electrode 126 is formed on the addition level of the data line level 124, in addition to the first embodiment is similar to the embodiment, the common electrode 126 and the data lines 124 entirely overlap.

如图40所示,公共电极126通过接触孔139a(参阅图61)与公共电极线126a或126b电连接,而像素电极127通过接触孔139b(参阅图61)与源极130b电连接。 40, the common electrode 126 is electrically connected to the common electrode line 126a or 126b through the contact hole 139a (see FIG. 61), the pixel electrode 127 and the electrode 130b via a contact hole 139b (see FIG. 61) and the source.

与数据线124重叠的黑基底层117的宽度被设计成具有小于公共电极126的宽度。 The data line 124 overlaps the width of the black base layer 117 is designed to have a width less than the common electrode 126.

在与数据线124重叠的公共电极126的部分、和最接近该部分的像素电极127之间的部分上有不透光膜。 There opaque film 127 on the portion between the portion of the common electrode 126, and the portion closest to the pixel electrode and the data line 124 overlap.

与第一实施方案类似地,在数据线124上形成的黑基底层117沿其整个长度上与数据线124重叠。 Similarly black base layer, is formed on the data line 124 of the first embodiment 117 overlaps the data line 124 along its entire length.

此外,如图40所示,液晶显示器件100中的数据线124被设计成之字形。 Further, as shown in FIG. 40, the liquid crystal display device 100 of the data line 124 is designed in a zigzag.

这就是说,根据第四实施方案的液晶显示器件100具有和第一实施方案的液晶显示器件10相同的结构,除了液晶显示器件100属于多域型,以及公共电极126、像素电极127和数据线124都是之字形。 That is, according to the same configuration as the liquid crystal display device 100 having a first embodiment and a liquid crystal display device 10 of the fourth embodiment, in addition to the liquid crystal display device 100 is a multi-domain type, and a common electrode 126, the pixel electrode 127 and the data line 124 is a zigzag.

第四实施方案中提到的“之字形”不仅代表的是一种线性部分的形状,如图43A所示都是相对纵向Z倾斜的,而且这种形状既包括了相对纵向Z倾斜的第一线性部分,又包括了平行于纵向Z延伸的第二线性部分,其中第一和第二线性部分可以彼此交替地连接,如图43B所示。 The fourth embodiment referred to "zigzag" not only represents the portion of a linear shape, as shown in FIG 43A are inclined relative to the longitudinal direction Z, and this includes both a shape inclined relative to the first longitudinal Z linear portion, and comprises a second linear portion extending parallel to the longitudinal Z, wherein the first and second linear portions may be alternately connected to one another, shown in Figure 43B. 换言之,所谓的“之字”包括了所有沿其纵向左右交替地重复倾斜的形状,而不是沿长度方向延伸。 In other words, the so-called "zig-zag" encompasses all around the longitudinal direction thereof inclined alternately repeated shape, rather than extending in the longitudinal direction. “之字”是否包括了沿纵向平行延伸的线性部分并没有关系。 "Zigzag" is included a linear portion extending along a longitudinal direction parallel to and does not matter. 第二线性部分相对于纵向倾斜的角度不会受到具体角度的限制,此外也没有必要将第二线性部分相对于纵向Z的倾斜角度设定为常数。 The second linear portion is inclined relative to the longitudinal angle is not limited by the specific angle, it is not necessary in addition to the second linear portion of the inclination angle with respect to the longitudinal direction Z is set to be constant.

根据第四实施方案的液晶显示器件100提供了与第一实施方案液晶显示器件10具备的优点相同的优点。 It provides the same advantages of the first embodiment of the liquid crystal display device 10 includes the advantages of the liquid crystal display device 100 of the fourth embodiment.

之字形的数据线124与具有线性数据线的液晶显示器件相比,液晶显示器件100可以增加开孔率。 Zigzag data line 124 as compared with the liquid crystal display device having a linear data lines, the liquid crystal display device 100 can increase the opening ratio. 下面解释其原因。 The reason for this is explained below.

图44是一个液晶显示器件201的平面图,包括线性数据线、线性公共电极、和线性像素电极。 FIG 44 is a plan view of a liquid crystal display device 201, a data line including linear, linear common electrode, and the linear pixel electrode. 图45是按照图44沿XXXXV-XXXXV线截取的剖面图。 FIG 45 is a sectional view taken XXXXV-XXXXV line 44 in accordance with FIG.

图44示出了各电极和构成液晶显示器件201的其他部件,其尺寸如下。 FIG 44 shows the respective electrodes and the other components constituting the liquid crystal display device 201 has the following dimensions. 下面提到的尺寸使用单位为微米(μm),除非另有说明。 Mentioned below using the size in microns (μm), unless otherwise indicated.

数据线24的宽度=10直接位于数据线24上方的公共电极26的宽度=19在直接位于数据线24上方的公共电极26形成的层面上形成的其他公共电极26的宽度=3.5像素电极27的宽度=3.5公共电极26和像素电极27之间距离=9.5因此,图44中示出的液晶显示器件201中的开口总面积A1的计算方法如下:A1=(9.5×6)×L=57L其中L代表开口的纵向长度。 Width of the data line 24 = 10 is located directly above the data line 24 of the common electrode width 26 = width of the other common electrode 19 is formed at the level of the common electrode located directly above the data line 24 26 26 formed = 3.5 pixel electrode 27 width = 3.5 distance between the common electrode and the pixel electrode 26 27 = 9.5 Thus, the method of calculating the total area of ​​the opening 201 in FIG. 44 shows the liquid crystal display device A1 is as follows: A1 = (9.5 × 6) × L = 57L wherein L represents the longitudinal length of the opening.

图46是液晶显示器件202的平面图,包括线性数据线、之字形公共电极、和之字形像素电极,图47是图46中沿线XXXXVII-XXXXVII截取的剖面图。 FIG 46 is a plan view of a liquid crystal display device 202, a data line including linear, zigzag common electrode, and the zigzag of the pixel electrode, FIG. 47 is a sectional view XXXXVII-XXXXVII, taken along line 46 in FIG.

各电极和构成图46所示的液晶显示器件202的其他部件的尺寸如下:数据线124的宽度=10直接位于数据线124上方的公共电极126的宽度=26.5 Other dimensions of each electrode member 46 and the configuration shown in FIG liquid crystal display device 202 is as follows: a = width of the data line 124 in the width of the common electrode 10 directly above the data line 124 126 = 26.5

在直接位于数据线124上方的公共电极126形成的层面上形成的其他公共电极126的宽度=3.5像素电极127的宽度=3.5公共电极126和像素电极127之间的距离=8.2因此,图46中示出的液晶显示器件202中的开口总面积A2的计算方法如下:A2=(8.2×6)×L=49.2L图48是液晶显示器件203的平面图,包括之字形数据线、之字形公共电极、和之字形像素电极,即根据第一实施方案的液晶显示器件10的平面图,图49是图48中沿线XXXXIX-XXXXIX截取的剖面图。 Other common electrode is formed at the level of the common electrode located directly above the data line 124 is formed of 126 126 Width = width of the pixel electrode 127 of 3.5 = 3.5 of a distance between the common electrode 127 and the pixel electrode 126 = 8.2 Thus, FIG. 46 the total area of ​​the opening 202 in the liquid crystal display device calculating method shown A2 as follows: A2 = (8.2 × 6) × L = 49.2L FIG. 48 is a plan view of a liquid crystal display device 203, a data line including zigzag, zigzag common electrode , and the zigzag of the pixel electrode, i.e., a plan view of a liquid crystal display device 10 of the first embodiment, FIG. 49 is a sectional view XXXXIX-XXXXIX, taken along line 48 in FIG.

图48中的各电极和构成液晶显示器件203的其他部件的尺寸如下:数据线124的宽度=10直接位于数据线124上方的公共电极126的宽度=19在直接位于数据线124上方的公共电极126形成的层面上形成的其他公共电极126的宽度=3.5像素电极127的宽度=3.5公共电极126和像素电极127之间的距离=9.5因此,图48中示出的液晶显示器件203中的开口总面积A3的计算方法如下:A3=(9.5×6)×L=57L比较上述A1、A2和A3面积可以十分明显地看出,包括了线性数据线、之字形公共电极和之字形像素电极的液晶显示器件202的面积A2要比包括了线性数据线、线性公共电极和线性像素电极的液晶显示器件201的面积A1小,然而,包括了之字形数据线、之字形公共电极和之字形像素电极的液晶显示器件203的面积A3等于面积A1。 Each of the electrodes 48 and the dimensions constituting the other components of the liquid crystal display device 203 is as follows: the data lines 124, width = 10 directly on the common electrode 124 above the data line width 126 = common electrode located directly above the data line 124 is 19 other common electrode 126 is formed on a 126-level width = width of the pixel electrode 127 of 3.5 = 9.5 = the distance between the 127 Accordingly, the openings 48 of the liquid crystal display device 203 illustrated in 3.5 and the pixel electrode common electrode 126 A3 total area calculated as follows: A3 = (9.5 × 6) × L = 57L compares the A1, A2 and A3 areas can be very clearly seen, including the linear data lines, zigzag zigzag pixel electrode and the common electrode the liquid crystal display device 202 of the area A2 than the area of ​​the liquid crystal display device comprising a linear data lines, and the linear common electrode 201 of the linear pixel electrode small A1, however, the data comprising a zigzag line, zigzag zigzag pixel electrode and the common electrode area of ​​the liquid crystal display device 203 is equal to the area A3 A1.

这就意味着将数据线124设计成之字形与包括线性数据线的液晶显示器件比较可以增加开孔率。 This means that the data line 124 in a zigzag design liquid crystal display device includes a linear comparison of the data lines may be increased opening ratio. 这是因为,在包括线性数据线、之字形的公共电极和之字形的像素电极的液晶显示器件202中,在图46中位于左面的数据线124和位于数据线124附近的像素电极127之间沿线XXXXVII-XXXXVII的距离比图48中的大7.5μm,因此公共电极126和像素电极127之间的间隙可以减少7.5μm/X的长度,X代表开口数,结果开口面积因此而减少。 This is because, between the data line comprises a linear, a liquid crystal display device of the pixel electrode and the common electrode zigzag zigzag 202, 124 located at the left of the data line and the pixel electrode located close to the data line 124 in FIG. 46 127 XXXXVII-XXXXVII distance along line in FIG. 48 large than 7.5 m, and therefore a gap 127 between the common electrode and the pixel electrode 126 can reduce the length of 7.5μm / X, X is representative of the numerical aperture, thereby reducing the opening area of ​​the result.

根据第四实施方案的液晶显示器件100可以用与根据第一实施方案的制成的液晶显示器件10的方法相同的方法制作。 The liquid crystal display device 100 of the fourth embodiment can be produced according to the same method as the liquid crystal display device made of a first embodiment 10 of the method. 特别是,由于液晶显示器件100中的数据线124、公共电极126和像素电极127都是以之字形状形成,形成它们的构图有所改变,以便定义之字形的数据线124、之字形的公共电极126和之字形的像素电极127。 In particular, since the liquid crystal display device 100 of the data lines 124, the common electrode 126 and the pixel electrode 127 are shaped in the form, the composition change thereof is formed so as to define the shape data line 124, the common zigzag the pixel electrode 126 and the electrode 127 zigzag. 除了形成数据线124、公共电极126和像素电极127图案的步骤之外,制作液晶显示器件100的步骤没有改变。 124 In addition, the step of the pixel electrode 126 and the common electrode 127 pattern, the data line is formed, manufacturing steps of the liquid crystal display device 100 is not changed.

下面说明根据第四实施方案构成的液晶显示器件的各部分及其变形。 The following description of each of the liquid crystal display device constituting a fourth embodiment and the variations thereof.

每个像素中的数据线124、公共电极126和像素电极127的回折数可以选自任何数值,只要它是一个奇数。 Each pixel data line 124, the number of inflection common electrode 126 and the pixel electrode 127 may be selected from any value, as long as it is an odd number. 这样保证液晶分子以顺时针方向扭曲的区域在数量和面积上等于液晶分子按照逆时针方向扭曲的区域。 This ensures that the liquid crystal molecules is twisted in a clockwise direction in the area is equal to the number and area of ​​the liquid crystal molecules twisted region in the counterclockwise direction. 这样加强了视角的对称性。 Such enhanced symmetry perspective. 因此,回折数可以限制为奇数值,例如1、3或5。 Accordingly, the folded-back number may be limited to an odd value, e.g., 3 or 5. 只要回折值是一个奇数值,1或任意大于等于3的数字都可以选作数据线124、公共电极126和像素电极127的回折数。 As long as the inflection value is an odd number, 1 or any number greater than or equal to 3 may be selected as the data line 124, the common electrode 126 and the pixel electrode 127 is folded back number.

回折值越小,开孔率越高,然而,回折值越小,弯曲图案越容易看到。 Back off value is, the higher the opening ratio, however, the inflection value, the easier the curved pattern seen. 此外,由于黑基底层117被设计成遵循数据线124、公共电极126和像素电极127的回折值,所以,如果数据线124、公共电极126和像素电极127的回折值很小,对黑基底层117进行构图将十分困难。 Further, since the black base layer 117 is designed to follow the data line 124, the common electrode 126 and the pixel electrode 127 is folded back values, so if the data line 124, the common electrode 126 and the pixel electrode 127 is folded back is very small, a base layer of black 117 is patterned will be very difficult.

相反,回折值越大,弯曲图案越容易被看作是一条线,黑基底层可以以很细的线的形式制成。 In contrast, the larger the back off value is, the easier the pattern is seen as a curved line, the black base layer may be made in the form of very fine lines. 然而回折值越大,开孔率越小。 However, the inflection value, the smaller the opening rate.

基于上述情况,发明人进行了实验,以求得到数据线124、公共电极126和像素电极127中的最佳回折值N。 Based on the above, the inventors conducted experiments in order to obtain the optimum value of inflection 124, the common electrode 126 and the pixel electrode 127 in data line N. 只要满足下列不等式(A),就可以确定最佳值N:30≤L/(N+1)≤40 (A)其中L代表开孔长度单位为微米(μm),参阅图42A。 As long as satisfying the following inequality (A), it is possible to determine the optimum value of N: 30≤L / (N + 1) ≤40 (A) wherein L represents the length of the opening in microns (μm), see Figure 42A.

黑基底层117可以设计成线性或者之字形。 Black base layer 117 may be designed in a linear or zigzag. 特别是当黑基底层117形成之字形时,优选的是黑基底层117根据数据线124的之字形被设计成之字形。 In particular, when the black base layer 117 is formed zigzag, it is preferable that a black base layer 117 is designed in a zigzag zigzag The data line 124. 虽然线性黑基底层可以比之字形黑基底层更容易地制成,但之字形黑基底层117将能够增加液晶显示器件100的开孔率。 Although the base layer may be a linear-shaped black black more readily than the base layer is made, but the zigzag black base layer 117 will be able to increase the opening ratio of the liquid crystal display device 100.

如图50所示,当从平面图观看时,优选的是黑基底层117的左端与数据线124的右端之间的距离、以及黑基底层117右端与数据线124左端之间的距离总是大于等于4微米(μm)。 As shown, when viewed from the plan, it is preferable that a distance between right and left black base layer 117 of the data lines 50, 124, 124 and the distance between the left end and the right end of the black base layer 117 is always greater than the data line equal to 4 micrometers (μm).

下面解释其理由。 The reason is explained below.

在面对液晶层113的黑基底层117表面和面对液晶层113的数据线124的表面之间的距离通常在3到4微米的范围内。 A black base layer facing the surface 117 of the liquid crystal layer 113 and the distance between the surface facing the liquid crystal layer 113 of the data line 124 is typically in the range of 3-4 microns. 参考图50,假定在连接到数据线124右端的黑基底层117左端的线和基板表面之间形成的角度表示为“α”,则来自黑基底层一侧的入射光被以角度α全部反射,其角度α大约等于45度。 Referring to FIG 50, it is assumed that an angle formed between the line 117 and the substrate surface of the left data line 124 is connected to the right end is represented as a black base layer "α", the incident light from the dark side of the base layer is totally reflected at an angle [alpha] that the angle α approximately equal to 45 degrees. 因此,当面对液晶层113的黑基底层117的表面和面对液晶层113的数据线124的表面之间的距离为最大时,即等于4微米时,如果黑基底层117的左端和数据线124的右端之间的距离大于等于4微米,有可能解决倾斜进入数据线124一端附近的光穿过黑基底层117,并且造成显示图象中的色彩混合,结果造成染色性降低的结果。 Thus, when the surface of the black base layer 117 facing the liquid crystal layer 113 and the distance between the surface facing the liquid crystal layer 113 of the data line 124 is maximum, i.e., equal to 4 micrometers, if the black data base layer 117 and the left end the distance between the right end of line 124 is greater than or equal to 4 microns, it is possible to solve the obliquely entering light near an end of the data line 124 through a black base layer 117, and color mixing caused by the displayed image, resulting in reduction of dyeing results.

为了保证在黑基底层117的左端和数据线124的右端之间的距离、以及黑基底层117的右端和数据线124的左端之间的距离总是大于等于4微米,黑基底层117和数据线124应该在所有地方彼此重叠4微米或更多。 To ensure the distance between the right and left black base layer 117 of the data line 124, and a black base layer 117 a distance between the right and left data line 124 is always greater than or equal to 4 microns, the base layer 117 and the black data line 124 should be 4 microns or more overlapping at all places with each other. 由于有源器件基板111和对置基板112通常被设计成4微米的可允许的公差,以便吸收匹配不正的情况,如果考虑到4微米的公差,就需要黑基底层117和数据线124的宽度大于等于8微米。 Since the active device substrate 111 and the counter substrate 112 is typically designed to allow tolerance of 4 microns in order to absorb errors of the matching case, if taking into account the tolerance of 4 microns, it is necessary width of the black base layer 117 and the data line 124 8 microns or greater.

图51和52示出了根据第四实施方案液晶显示器件100中的黑基底层117的布局的实例。 51 and FIG. 52 shows an example of the layout 100 according to a fourth embodiment of a liquid crystal display device 117 of the black base layer.

在图51中示出的布局中,数据线124被设计成10微米的宽度,公共电极126的宽度被设计成19微米,带有大量梳齿的公共电极126被设计具有7次的回折值,并且黑基底层117被设计具有13.5微米的宽度。 In the layout shown in FIG. 51, the data line 124 is designed to be a width of 10 microns, a width of the common electrode 126 is designed to be 19 microns, with a large number of comb teeth of the common electrode 126 is designed to have a value of 7 times folded back, and a black base layer 117 is designed to have a width of 13.5 microns.

黑基底层117和数据线124彼此重叠的最小宽度是在公共电极126或数据线124弯曲之处,即在线XX处。 The minimum width of the black base layer 117 and the data line 124 are overlapped with each other at the common electrode 126 or the data line 124 is bent, i.e. at line XX. 如图51所示出的布局中,黑基底层117和数据线124相互重叠的最小宽度等于8微米。 The layout shown in FIG. 51, the minimum width of the black base layer 117 and the data line 124 overlap each other is equal to 8 microns.

在图52所示出的布局中,数据线124被设计宽度为10微米,公共电极126被设计宽度为19微米,带有大量梳齿的公共电极126被设计具有5次的回折值,而黑基底层117被设计宽度为16微米。 In the layout shown in FIG. 52, the data line 124 is designed width of 10 m, a width of the common electrode 126 is designed to be 19 microns, with a large number of comb teeth of the common electrode 126 is designed to have a value of 5 times folded back, the black the width of the base layer 117 is designed to 16 microns.

黑基底层117和数据线124相互重叠的最小宽度位于公共电极126或数据线124弯曲的位置上,即位于XX线上。 The minimum width of the black base layer 117 and the data line 124 overlap each other is located in the curved position of the common electrode 124 or the data lines 126, i.e., located on the line XX. 在图52示出的布局中,黑基底层117和数据线124相互重叠的最小宽度等于8微米。 In the layout shown in FIG. 52, the minimum width of the black base layer 117 and the data line 124 overlap each other is equal to 8 microns.

根据第四实施方案的液晶显示器件100中的黑基底层117的最小宽度,例如图51和图52中示出布局中的上述最小宽度确定如下。 The minimum width of the liquid crystal display device 100 in the fourth embodiment of the black base layer 117, e.g. FIG. 51 and FIG. 52 shows the layout of the minimum width is determined as follows.

图53示出了黑基底层117、数据线124和公共电极126之间的位置关系。 FIG 53 shows the positional relationship between the black base layer 117, the data lines 124 and the common electrode 126. 参考图53,确定黑基底层117最小宽度的方程确定如下。 Referring to FIG 53, the minimum width is determined determining equations black base layer 117 as follows.

假定数据线124的宽度表示为“D”,当沿数据线124延伸的方向投影时,斜线的长度表示为“LS”,数据线124延伸的方向和斜线之间形成的角度表示为“θ”,不允许倾斜的光进入数据线124的黑基底层117最小宽度Dmin表示为:Dmin=D+LS×tanθ-(D-8)×2[μm] (B)在图54和55示出的实例中,数据线124设计宽度为10微米,并进一步被设计成之字形,包括沿数据线124的纵向Z延伸的线性部分,如图43B所示。 Width of the data line 124 is assumed to be expressed as "D", when the data line 124 extending in the direction of projection, oblique lines represents the angle between the length of "the LS ', the data lines 124 extending in a direction oblique lines is formed and is represented as" θ ", 117 does not allow the minimum width of the inclined light enters the data line 124 is represented as a black base layer Dmin: Dmin = D + LS × tanθ- (D-8) × 2 [μm] (B) shown in FIGS. 54 and 55 examples of the data line 124 design width of 10 microns, and is further designed to zigzag, Z includes a linear portion extending longitudinally along the data line 124, shown in Figure 43B. 图54和55中示出的数据线124的边沿位于自图52示出的数据线124回折中的每个凹部的底部后退3微米处。 124 back to the bottom of each recess compromise edge 54 and 55 shown from the data line 124 is located 52 shows the data line back 3 microns. 与图52中示出的同种情况相比,公共电极126由凹部限定的边沿超出数据线124 4.5微米,以及在与如图52所示出的公共电极边沿的突起位置相同位置上突起。 52 in comparison with the same kind of situation is shown in FIG., The common electrode defined by the recess 126 beyond the edge of the data lines 124 4.5 microns, and the projection position of the projection at the same position of the common electrode and the edge 52 shown on FIG. 带很多梳齿的公共电极126被设计成带五个回折的之字形。 The common electrode 126 with a lot of comb teeth are designed with five zigzag folded back. 在上述条件下,黑基底层117可以有10微米的宽度。 Under the above conditions, the black base layer 117 can have a width of 10 microns. 黑基底层117和数据线124相互重叠的宽度在公共电极126或数据线124弯曲处最小,也就是说,在线XX处。 Black base layer 117 and the data line 124 overlap each other at the minimum width of the common electrode 126 at the bend 124 or the data lines, i.e., at the line XX. 在图54和55中示出的实例中,黑基底层117和数据线124相互重叠的最小宽度等于8微米。 In FIGS. 54 and 55 in the example shown, the minimum width of the black base layer 117 and the data line 124 overlap each other is equal to 8 microns.

与图52示出的实例比较,黑基底层117可以将宽度减少到6微米,确保了开孔率增加。 Compared with the example shown in FIG. 52, a black base layer 117 can be reduced to a width of 6 microns, to ensure that the opening ratio increases.

图54和55中示出的公共电极126在除了像素电极127与数据线124重叠的部分以外的部分上按照如图43A所示的之字型图案弯曲。 54 and FIG. 55 shows the common electrode 126 except for the portion on the pixel electrode 127 overlaps the data line 124 of the curved portion shaped in accordance with the pattern shown in FIG. 43A.

与数据线124重叠的公共电极126具有超出数据线124 4.5微米的边缘,这个边缘在顶部被设计成V字型,以便向显示区域施加足够的电压。 The common electrode 124 overlaps the data line of the data lines 126 has an edge 124 beyond 4.5 m, the top edge is designed to be V-shaped, in order to apply a sufficient voltage to the display area.

如前所示,黑基底层117不允许倾斜光进入数据线124的最小宽度Dmin由下式表达:Dmin=D+LS×tanθ-(D-8)×2[μm] (B)在图54和55示出的黑基底层117的实例中,数据线124的边缘被设计成,在从图52所示的数据线124回折凹部的底部算起,向数据线124的外侧被替换了3微米,同时,在数据线124回折部突起的顶部,数据线124被向内替换了3微米,以便形成沿数据线124纵向延伸的线性部分。 As previously indicated, the base layer 117 does not allow the black light enters obliquely the minimum width Dmin of the data line 124 is expressed by: Dmin = D + LS × tanθ- (D-8) × 2 [μm] (B) in FIG. 54 examples 55 and base layer 117 shown in black, the edge data line 124 is designed to be at the bottom of the counting portion 124 folded back from the recessed data line 52 shown in FIG, 3 is replaced by the data lines 124 micrometers outward of Meanwhile, the data line 124 at the top portion folded back projection, the data line 124 is 3 microns replaced inwardly so as to form linear portions along the data line 124 extending longitudinally.

可替换的是,如图53所示,只有在图52示出的数据线124回折部中凹部底部可以向外、从没有被替换的数据线124回折凹部底部算起用3微米替换数据线124。 Alternatively, as shown in 53, only 52 124 folded-back portion shown in the data lines bottom of the concave portion may be outwardly date data 3 micrometers Alternatively line 124 from the bottom flaps recessed portion 124 back has not been replaced data line.

在上述这种布局中,与图54和55示出的实例类似,黑基底层117可以设计成具有10微米的宽度,保证了开孔率的增加。 In this arrangement described above, FIG. 54 and 55 similar to the example shown, a black base layer 117 may be designed to have a width of 10 microns, to ensure that the increase in aperture ratio.

如图56所示,数据线124以与图52示出的数据线相同的方式形成,并且浮动电极181可能在数据线124回折部的凹部底部附近形成。 As shown in FIG. 56, the same data line 124 in FIG. 52 shows a data line is formed, and the floating electrode 181 may be formed near the bottom of the recess portion folded back 124 data lines. 浮动电极181可以由构成公共电极126的第一金属层构成。 Floating electrode 181 may be formed of a first metal layer constituting the common electrode 126. 这种浮动电极181可以用来屏蔽来自图53所示区域的光,在这种情况下,与图54和55示出实例类似,黑基底层117可以设计成具有10微米的宽度,保证了开孔率的增加。 Such floating electrode 181 may be used to shield the light from the region shown in FIG. 53, in this case, 54 and 55 shows an example similar to the black base layer 117 may be designed to have a width of 10 microns, to ensure that the opening increase the porosity of.

此外,如图57示出的,公共电极126可以设计成进一步包括从与数据线124重叠的公共电极126的回折部顶部突出来的突起182。 In addition, 57, a common electrode shown in FIG. 126 may be designed to further comprise from the top of the folded-back portion of the common electrode 124 overlaps the data line 126 to the protrusion 182 protrudes.

图58示出的像素包括了上述带有突起182的公共电极126。 FIG 58 shows a pixel includes a common electrode 126 having the above-described protrusion 182. 在示出的像素中,突起182固定在包括突起182顶部的域边界发生旋转位移的位置上,保证了显示图象的稳定性,即使显示屏被手指触动。 In the pixel illustrated, the projection comprises a projection 182 fixed to the top position of the domain boundary 182 disclination on, to ensure the stability of the display image, even if the display screen is touched finger.

在根据第四实施方案的液晶显示器件100中,构成对置基板112的彩色层118可以设计成与数据线124、公共电极126和像素电极127一样的之字型。 In the liquid crystal display device 100 according to the fourth embodiment, a color layer constituting the counter substrate 112, 118 can be designed to data line 124, the common electrode 126 and the pixel electrode 127 of the same font. 特别是,当彩色层118形成之字型的时候,优选的是,彩色层118由于与数据线124的之字型一致的之字型。 In particular, when the colored layer 118 is formed zigzag, it is preferable that the color layer 118 is consistent because the data line 124 of the shaped zigzag.

根据第四实施方案的液晶显示器件100可以设计成进一步包括:在每个像素柱中,在液晶分子沿顺时针方向扭曲的像素子区和液晶分子沿逆时针方向扭曲的像素子区之间的稳定电极。 The liquid crystal display device of the fourth embodiment 100 may be designed to further comprising: in each pixel column, the pixel sub-regions twisted in the clockwise direction and the liquid crystal molecules in the liquid crystal molecules between the pixel sub-regions of the twisted counterclockwise stable electrode. 稳定电极可以保证像素子区之间稳定的边界,从而,稳定液晶分子的定向。 Stable to ensure the stability between the pixel electrode may be the sub-region boundary, thereby stabilizing the orientation of the liquid crystal molecules. 这样即使显示屏被手指摩擦,手指印也不会保留在显示屏上,保证了显示图象清晰度得到提高。 Even though the display screen is a finger rubbing, fingerprints are not retained on the screen, to ensure that the display image sharpness is improved.

虽然日本专利申请No.2000-326814(日本待审查专利公告No.2002-131781),属于本申请的受让人提交的,且没有公开,它在后面说明了下本发明强调的优点,但是在此的解释并不意味着申请人承认日本专利申请No.2000-326814是在本发明之前法定的现有技术。 While the Japanese Patent Application No.2000-326814 (Japanese Unexamined Patent Publication No.2002-131781), the assignee of the present application is filed, and is not disclosed, it will be described later emphasizes the advantages of the present invention, but in this interpretation does not mean that the applicant admitted that Japanese Patent application No.2000-326814 statutory prior art before the present invention. 在下面说明的日本专利申请No.2000-326814的有关内容仅仅是为了更好理解本发明的目的。 Japanese Patent Application described below relating to the contents of No.2000-326814 is only for purposes of better understanding the present invention.

日本专利申请No.2000-326814建议了带有分别从V字型公共电极和V字型的像素电极的顶部向外延伸的公共辅助电极和像素辅助电极的V字型公共电极和V字型的像素电极公共辅助辅助公共。 Japanese Patent Application No.2000-326814 suggests a V-shaped V-shaped common electrode and auxiliary common electrode and the pixel with the auxiliary electrode extending from the top of the pixel electrode and the common electrode of the V-shaped V-shaped outwardly public assistance public assistance pixel electrode. 公共辅助电极和像素辅助电极的末端与像素电极和公共电极重叠。 End of the pixel electrode and the common auxiliary electrode and the pixel electrode and the common auxiliary electrode overlap.

然而上述V字型公共和像素电极不能应用在根据第四实施方案的液晶显示器件100上,因为像素电极127和公共电极126形成在液晶显示器件100的同一层上。 However, the V-shaped common electrode and the pixel can not be used in a liquid crystal display device 100 of the fourth embodiment, since the pixel electrode 127 and the common electrode 126 is formed on the same layer of the liquid crystal display device 100 according to. 此外,对于将V字型公共电极和像素电极应用到液晶显示器件100上还需要防止制作步骤的增加。 In addition, the V-shaped common electrode and the pixel electrode applied to the liquid crystal display member 100 is necessary to prevent further increase in manufacturing steps.

因此,为了使液晶显示器件100包括能保证在像素子区之间有一个稳定的边界的稳定电极,如图59所示,浮动稳定电极140形成在像素电极127的回折部顶部之下,且与之重叠。 Thus, the liquid crystal display device 100 in order to ensure between the pixel includes a sub-region has a steady stable electrode boundary, as shown, stabilizing the floating electrode 140 is formed below the top 59 in the folded-back portion of the pixel electrode 127, and with the overlap. 每个浮动稳定电极140都由第二金属层构成,从而,不会与像素电极127电连接。 Each floating electrode 140 by the second stabilizing metal layer, thus, will not be electrically connected to the pixel electrode 127. 每个浮动稳定电极140都与像素电极127充分重叠,并且向像素子区之间的边界延伸。 Each floating electrode 140 are stabilized sufficiently overlaps the pixel electrode 127, and extends to a boundary between the sub-pixel region.

如图61所示,液晶显示器件100可以被设计成包括在第二夹层绝缘膜25的第一膜25a之下的像素辅助电极135。 As shown in FIG. 61, the liquid crystal display device 100 may be designed to include a pixel below the first film 25a of the second interlayer insulating film 25 of the auxiliary electrode 135. 像素辅助电极135由第二金属层构成,并且与TFT130的源极130b一体形成。 Auxiliary pixel electrode 135 composed of the second metal layer, and is formed integrally with the source electrode TFT130 130b.

图62A是在图60中示出的液晶显示器件中形成的ITO层的平面图,图62B是除了在图60中示出的液晶显示器件中形成的ITO层以外的各层的平面图。 FIG 62A is a plan view of the ITO layer in the liquid crystal display device shown in FIG 60 is formed, and FIG 62B is a plan view of the respective layers other than the layer of ITO in a liquid crystal display device shown in FIG. 60 are formed. 如图62A和62B所示,像素辅助电极135由与公共电极线126a和126b重叠的第一部分135a和第二部分135b、以及在像素电极127下面形成的第三部分135c构成,从而定义了在第一和第二部分135a和135b与公共电极线126a和126b之间的存储电容。 And FIG. 62A, the pixel electrode 135 overlaps the auxiliary common electrode wires 126a and 126b and the first portion 135a and second portion 135b, and a third portion 135c constituting the pixel electrode 127 is formed beneath 62B, thereby defining the first a storage capacitor between the second portions 135a and 135b and the common electrode lines 126a and 126b. 第三部分135c为之字型,与第一部分135a和第二部分135b相互连接。 A third portion 135c whom shaped, interconnected with the first portion 135a and second portion 135b. 第一部分135a、第二部分135b和第三部分135c以I字型布置。 A first portion 135a, second portion 135b and third portion 135c are arranged in I-shape.

与第一实施方案类似,液晶显示器件100中的像素辅助电极135a和135b可以设计成在每个柱中具有这样的倾斜边缘,使得由摩擦确定的摩擦方向或者液晶的定向方向、与在像素电极127(以及向其施加与像素电极127相同电压的像素辅助电极135)和公共公共电极126(以及与向其施加与公共电极126相同电压的公共电极线126a和126b)上施加的电场方向之间的关系就可以确定,保证了该液晶定向方向与该电场方向重叠。 Similar to the first embodiment, the auxiliary pixel electrode 135a in the liquid crystal display device 100 and 135b may be designed to have a beveled edge on each column, so that the rubbing direction determined by the rubbing direction of the orientation or the liquid crystal, and a pixel electrode between 127 (and the same voltage is applied thereto, the pixel electrode 127 of the auxiliary pixel electrode 135) is applied to the electric field direction of the common electrode 126 and the common (same voltage is applied thereto and a common electrode 126 and the common electrode lines 126a and 126b) the relationship can be determined, to ensure that the orientation direction of the liquid crystal overlaps the field direction. 如果液晶定向方向沿顺时针方向以某个锐角旋转,整个在像素电极127和公共公共电极126包围的显示区域中,且在液晶分子以顺时针方向扭曲的像素子区附近的电极中;或者上述关系得以确定,保证液晶定向方向与电场方向重叠;如果液晶定向方向沿逆时针方向以某个锐角旋转,整个在像素电极127和公共公共电极126包围的显示区域中,且在液晶分子以逆时针方向扭曲的像素子区附近的电极。 If a liquid crystal is oriented at an acute angle to the direction of rotation in the clockwise direction, the pixel electrode 127 and the entire display region of the common electrode 126 surrounded by the common, and in the vicinity of the electrodes of the liquid crystal molecules is twisted in a clockwise direction in the pixel sub-region; or above relationship is determined, to ensure that the liquid crystal alignment direction to overlap with the direction of the electric field; if the liquid crystal is oriented to a direction rotated counterclockwise at an acute angle, the pixel electrode 127 and the entire display region of the common electrode 126 surrounded by the common, and the liquid crystal molecules in a counterclockwise an electrode region near the pixel sub-twisted direction. 这种结构对应于已经在第一实施方案中提到的反向旋转阻止结构36。 This structure corresponds to the reverse rotation preventing structure 36 already mentioned in the first embodiment.

参考图62A,与由第二金属层构成的像素辅助电极135c的回折部的顶部连接的电极也是由第二金属层构成的,因此,不是浮动电极。 Referring to FIG 62A, the pixel composed of the second auxiliary electrode layer of metal on top of the folded back portion of the electrode 135c are connected by a second metal layer, and therefore, is not floating electrode. 这种电极被称为稳定电极142。 Such an electrode is referred to as a stable electrode 142.

稳定电极142保证了每个像素子区中的电场可以稳定地指向液晶分子扭曲的方向,进而保证像素子区的稳定分区。 The electrode 142 to ensure a stable electric field for each pixel sub-region can be stably pointing direction of the liquid crystal molecules twisted, thereby ensuring the stable partitioning the pixel sub-region.

在图60示出的液晶显示器件中,由第二金属层构成的像素辅助电极135可以被设计包括稳定电极142,其自像素辅助电极135的回折部的顶部、沿液晶分子以反向旋转的两个像素子区之间的边界处向外延伸。 In the liquid crystal display device shown in FIG. 60, the pixel electrode is formed of a second auxiliary metal layer 135 may be designed to include a stabilizing top electrode 142, which is folded back portion of the pixel from the auxiliary electrode 135, the liquid crystal molecules in a reverse direction of rotation extending outwardly at the boundary between the two sub-pixel regions. 稳定电极142由第二金属层构成,确保每个像素子区中的液晶分子旋转平稳。 Stable electrode is made of a second metal layer 142, to ensure that each sub-pixel region of the liquid crystal molecules in the smooth rotation.

由第二金属层构成的公共辅助电极也可以保证在每个像素子区中液晶分子的平稳旋转。 Common auxiliary electrode made of the second metal layer can also ensure a smooth rotation of the liquid crystal molecules in each sub-pixel region.

根据第四实施方案的液晶显示器件100可以应用于图42B示出的液晶显示器件上,也就是说,这是一种有源器件基板的开口在垂直于数据线124延伸方向的方向延伸的液晶显示器件。 The liquid crystal display device liquid crystal display device 100 of the fourth embodiment can be applied to the embodiment in FIG. 42B shows, that this is an active liquid crystal device substrate opening extending in the direction of the data line 124 extends in a vertical direction display device.

对于图42A示出的液晶显示器件,即,它是一种有源器件基板的开口是沿与垂直于数据线124延伸方向相同的方向延伸的液晶显示器件,液晶垂直注入其中;然而,对于如图42B所示的液晶显示器件,即,这种液晶显示器件其有源器件基板的开口沿垂直于数据线124延伸方向的方向延伸,因而液晶是水平注入其间的。 For the liquid crystal display device shown in FIG. 42A, i.e., an opening which is an active device substrate is a liquid crystal display device in the direction of the data line 124 extends along the same vertical direction extending perpendicular to the liquid crystal is injected therein; however, for such an opening extending in a direction perpendicular to the direction of the liquid crystal display device shown in FIG. 42B, i.e., the liquid crystal display device which is an active device substrate extending direction of the data line 124, and thus the level of the liquid crystal is injected therebetween. 在后一种情况下,数据线124是以线性形成的,定义了栅极的栅极线成之字形。 In the latter case, the data line 124 in a linear form, the definition of the gate of the gate lines in a zigzag. 第五实施方案图63A是根据本发明第五实施方案的平面开关模式有源矩阵型液晶显示器件180的剖面图,与图41对应,后者是是根据第三实施方案液晶显示器件100的剖面图。 Fifth embodiment FIG. 63A is a sectional view of an active matrix type liquid crystal display device 180 according to the fifth embodiment plane switching mode embodiment of the present invention, corresponding to FIG. 41, which is a cross-sectional view according to a third embodiment of a liquid crystal display device 100 Fig.

在第三实施方案液晶显示器件100中,除了公共电极126以外,像素电极127也形成在第二夹层绝缘膜125的第二膜126b上。 In a third embodiment 100 of a liquid crystal display device, in addition to the common electrode 126, the pixel electrode 127 is also formed on the second film 126b of the second interlayer insulating film 125.

在第五实施方案的液晶显示器件180中,像素电极127是在第一夹层绝缘膜123上的第二金属膜上形成的,类似于根据二实施方案的液晶显示器件80。 In the liquid crystal display device 180 of the fifth embodiment, the pixel electrode 127 is a second metal film on the first interlayer insulating film 123 is formed, similar to the liquid crystal display device 80 of the two embodiments. 因为像素电极127是由第二金属层构成的,所以第五实施方案的液晶显示器件180的开孔率小于第一实施方案的液晶显示器件10。 Since the pixel electrode 127 is made of the second metal layer, the opening ratio of the liquid crystal display device 180 of the fifth embodiment is smaller than the first liquid crystal display device 10 of the embodiment. 因此,由于像素电极127由不同于形成公共电极126的层面构成,所以像素电极127和公共电极126不会彼此短路,保证成品率得到提高。 Thus, since the pixel electrode 127 is formed the common electrode 126 is different from the level of configuration, the pixel electrode 127 and the common electrode 126 is not short-circuited to each other, to ensure improved yield.

此外,它还可能在由第二金属层构成的像素电极127和由第一金属层构成的公共电极线126a和126b之间形成存储电容。 In addition, it is possible to form a storage capacitor between the pixel electrode 127 and the common electrode lines 126a and 126b made of a first metal layer made of the second metal layer. 这样保证了液晶层113的总的存储电容、以及显示图象的稳定性得到加强。 This ensures that the total storage capacitance of the liquid crystal layer 113, and stability of the display image is strengthened.

如前所示,公共电极126可以包括稳定电极,其自公共电极126的回折部的顶端、沿液晶分子以顺时针方向扭曲的像素子区和液晶分子以逆时针方向扭曲的像素子区之间的边界向外延伸,在这种情况下,稳定电极可以由构成公共电极126的ITO层构成。 As previously indicated, the common electrode 126 may include a stabilizing electrode, which sub-regions between the pixel from the distal end of the folded-back portion of the common electrode 126, in a clockwise direction along the twisted liquid crystal molecules in the pixel sub-region and the liquid crystal molecules are twisted counterclockwise the boundary extends outwardly, in this case, may be constituted by a stable electrode ITO layer constituting the common electrode 126. 类似地,像素电极127可以包括稳定电极,其自像素电极127的回折部的顶端、沿液晶分子以顺时针方向扭曲的像素子区和液晶分子以逆时针方向扭曲的像素子区之间的边界向外延伸,在这种情况下,稳定电极可以由构成像素电极127的ITO层构成。 Similarly, the pixel electrode 127 may include an electrode stabilizing, which is folded back to the top portion of the pixel electrode 127 from the boundary between the sub-pixel region in a clockwise direction along the twisted liquid crystal molecules in the pixel sub-region and the liquid crystal molecules are twisted counterclockwise extends outwardly, in this case, may be constituted by a stable electrode layer made of ITO of the pixel electrode 127. 这些稳定电极确保了在像素子区边界处液晶分子旋转的稳定性。 These stabilizers ensure stability of the electrodes of the liquid crystal molecules at the boundary pixel sub-region of the rotation. 第六实施方案图63B是根据本发明第六实施方案的平面开关模式有源矩阵型液晶显示器件185的剖面图,与图41对应,后者是根据第三实施方案液晶显示器件100的剖面图。 FIG 63B is a sixth embodiment of an active matrix type liquid crystal display device according to a sixth embodiment plane switching mode embodiment of the present invention, the sectional view 185, corresponding to FIG. 41, which is a sectional view of the liquid crystal display device 100 according to the third embodiment .

在第三实施方案液晶显示器件100中,与第二膜125b一起构成第二夹层绝缘膜125的第一膜125a形成在整个像素区上。 In a third embodiment 100 of a liquid crystal display device, and the second film with the first film 125b constituting the second interlayer insulating film 125 is formed over the entire 125a of the pixel region. 相反,第二膜125b可以只在与数据线124重叠的公共电极126之下形成。 In contrast, the second film 125b may be formed only below the common electrode 126 overlaps the data line 124.

在像素显示区中,公共电极126是由构成栅极的第一金属层构成的,在除了由透明金属组成公共电极126的区域之外的区域中,与数据线124重叠。 In the display pixel area, the common electrode 126 by a first metal layer constituting the gate electrode constituted by a transparent area other than the common electrode composed of a metal region 126, data line 124 overlap.

根据第六实施方案,不需要在超出所需的更大的区域上形成第二膜125b,借此,可以防止在公共电极126和数据线124之间的增加寄生电容。 According to the sixth embodiment, it is unnecessary to form a second film 125b beyond a larger area required, thereby, possible to prevent an increase in parasitic capacitance between the common electrode 126 and the data line 124.

像素电极127可以与数据线124一起形成在第一夹层绝缘膜123上。 The pixel electrode 127 may be formed on the first interlayer insulating film 123 together with the data line 124.

由于公共电极126是在第一夹层绝缘膜123上的第一金属膜上、在除了在由第二膜125b上形成的透明金属膜构成的公共电极126的区域之外的区域上构成的,所以,第六实施方案的液晶显示器件185的开孔率小于第四实施方案的液晶显示器件100。 Since the common electrode 126 is a first metal film on the first interlayer insulating film 123, and on a region except in the region of the common electrode 126 is formed of a transparent metal film on the second film 125b made of the configuration, so the liquid crystal display device, the opening ratio of the liquid crystal display device 185 of the sixth embodiment of the fourth embodiment is less than 100. 然而,由于公共电极126由不同于形成像素电极127的层面构成,所以公共电极126和像素电极127不会彼此短路,保证成品率得到提高。 However, since the pixel electrode 126 is formed the common electrode 127 is different from the configuration level, the common electrode 126 and the pixel electrode 127 will not be short-circuited to each other, to ensure improved yield.

在液晶分子以顺时针方向扭曲的像素子区和液晶分子以逆时针方向扭曲的像素子区之间形成的稳定电极可以设计成自像素电极127和公共电极126的回折部的顶部向外延伸,与第五实施方案类似地,因为像素电极127形成在与公共电极126的层面不同的层面上。 Extending outwardly of a top electrode is formed stably between the pixel sub-regions of the liquid crystal molecules twisted in the clockwise direction and the sub-regions of the pixel of the liquid crystal molecules in a counterclockwise twist can be designed from the folded back portion of the pixel electrode 127 and the common electrode 126, Similarly to the fifth embodiment, since the pixel electrode 127 is formed on the common electrode 126 and the level of the different levels.

根据第六实施方案的平面开关模式有源矩阵型液晶显示器件185可以增加开孔率,类似于根据第一实施方案的液晶显示器件10。 The in-plane switching mode of the sixth embodiment of an active matrix type liquid crystal display device 185 can increase the opening ratio, similar to the liquid crystal display device 10 according to the first embodiment. 第七实施方案根据第七实施方案的液晶显示器件具有与第一到第六实施方案中的任意的液晶显示器件相同的结构,除了根据第七实施方案的液晶显示器件设计成没有包括作为对置基板一部分而形成的彩色层。 The seventh embodiment has the same structure as any of the first to sixth embodiments of the liquid crystal display device, a liquid crystal display device according to the seventh embodiment, in addition to the liquid crystal display device designed according to the seventh embodiment does not include a counter a color layer formed by a portion of the substrate. 因此,第七实施方案提供的平面开关模式有源矩阵型液晶显示器件显示的是黑白图象。 Thus, a seventh embodiment plane switching mode provides an active matrix type liquid crystal display device is a black and white display image.

包括上述结构的第七实施方案的液晶显示器件具有较高的光使用率,确保高亮度下的低功耗。 The liquid crystal display device comprising the above-described structure of the seventh embodiment has a higher light utilization, to ensure low power consumption at high brightness. 第八实施方案在上述第一到第七实施方案中,形成的彩色层和黑基底层构成作为对置基板的一部分。 Eighth embodiment In the first embodiment to the seventh embodiment, formed in the base layer and a black colored layer is configured as part of the counter substrate. 在第八实施方案的平面开关模式有源矩阵型液晶显示器件中,彩色层、黑基底层、或者彩色层和黑基底层两者不作为对置基板的一部分而形成,只是作为有源器件基板的一部分而形成。 In the eighth embodiment-plane switching mode active matrix type liquid crystal display device, a color layer, a black base layer, or both the color layer and the base layer is formed without the black part of a counter substrate, the active device only as substrate part is formed.

通过形成彩色层、黑基底层或者彩色层和黑基底层作为有源器件基板的一部分,有可能增加这些层和已经在有源器件基板中形成的部分(例如数据线)之间定位的精确性,这样保证了黑基底层和其他层的宽度可以减少,而开孔率进一步得到提高。 By forming a color layer, a black layer and a black colored base layer or base layer as part of an active device substrate, it is possible to increase and a portion positioned between these layers (e.g., data lines) has been formed in the active device substrate accuracy , thus ensuring that the width of the black base layer and other layers can be reduced, and the opening ratio is further improved.

在第一、第二、第四或第五实施方案中,作为有源器件基板的一部分形成的彩色层和/或黑基底层,可以被构成第二夹层绝缘膜的有机膜覆盖。 In the first, second, fourth or fifth embodiments, as part of the active device substrate forming a color layer and / or a black base layer, the organic film may be configured to cover the second interlayer insulating film. 有机膜可以防止在有源器件基板中形成的彩色层和/或黑基底层中的杂质被洗提到液晶层中,从而,保证稳定性得到加强。 The organic film can prevent the color layer and / or black impurities base layer formed in the active device substrate is eluted into the liquid crystal layer, thereby ensuring the stability enhanced.

在第一、第二、第四或第五实施方案中,当第二夹层绝缘膜是由无机膜构成的第一膜构成的、而由有机膜构成第二膜的时候,彩色层和/或黑基底层可以夹在第一和第二膜之间。 In the first, second, fourth or fifth embodiments, when, by the time the organic film and the second film, the first film of the second color layer interlayer insulating film is formed of an inorganic film and / or black base layer may be sandwiched between the first and second films. 有机膜可以防止在有源器件基板中形成的彩色层和/或黑基底层中的杂质被洗提到液晶层中,并且进一步防止有源器件基板受到彩色层中的电荷和/或离子运动的影响,从而,保证可靠性得到提高。 The organic film can prevent the color layer and / or a black base layer formed in the active device substrate of the liquid crystal layer, impurities are eluted, and subjected to further prevent the active device substrate charge color layers and / or ion motion influence, thus, ensure the reliability is improved.

图64和65示出了根据第八实施方案的平面开关模式有源矩阵型液晶显示器件,它对应于图40和41示出的根据第四实施方案的液晶显示器件100,其中第二夹层绝缘膜125由无机膜构成的第一膜125a和由有机膜构成的第二膜125b构成的,彩色层118和黑基底层117夹在第一膜125a和第二膜125b之间。 64 and FIG. 65 shows an active matrix type liquid crystal display device according to an eighth embodiment-plane switching mode, which corresponds to FIG. 40 and the liquid crystal display device according to a fourth embodiment of the embodiment shown in 10041, wherein the second interlayer insulating the first film 125a and the second film 125b made of an organic film made of a film 125 formed of an inorganic film, a black color layer 118 and the substrate layer 117 sandwiched between the first film and the second film 125b 125a. 图64是根据第八实施方案的液晶显示器件的平面图,图65是图64沿线XXXXXXV-XXXXXXV的剖面图。 FIG 64 is a plan view of the liquid crystal display device of the eighth embodiment, FIG. 65 is a sectional view along line 64 of XXXXXXV-XXXXXXV. 第九实施方案根据第一实施方案的液晶显示器件10、根据第二实施方案的液晶显示器件80、根据第三实施方案的液晶显示器件85、根据第四实施方案的液晶显示器件100、根据第五实施方案的液晶显示器件180、根据第六实施方案的液晶显示器件185、根据第七实施方案的液晶显示器件、根据第八实施方案的液晶显示器件均可以应用到电子器件上。 A ninth embodiment of the liquid crystal display device according to the first embodiment 10, the liquid crystal display device according to the second embodiment 80, the liquid crystal display device 85 according to the third embodiment, the liquid crystal display device according to a fourth embodiment 100 according to the first the liquid crystal display device 180 of the five embodiments, the liquid crystal display device 185 according to the sixth embodiment, the liquid crystal display device according to the seventh embodiment, the liquid crystal display device according to the eighth embodiment can be applied to an electronic device. 下面说明部分实例。 The following example illustrates the portion.
