平面内切换型液晶显示装置【技术领域】本发明是关于一种液晶显示装置，特别是关于一种平面内切换型（In-Plane Switching, IPS)液晶显示装置。 A plane switching type liquid crystal display device TECHNICAL FIELD The present invention relates to a liquid crystal display device, particularly with regard to an in-plane switching type (In-Plane Switching, IPS) liquid crystal display device. 【背景技术】液晶显示装置，是平面显示装置中的一种，经过几十年来的发展，不仅在笔记本计算机领域得到广泛应用，还在监视器与电视等领域占据越来越大的份额。 BACKGROUND liquid crystal display device is a device for the flat panel display, after decades of development, has been widely used not only in the field of notebook computers, monitors and TVs still account for a growing share of the field. 为了克服现有技术中液晶显示装置的视角小的缺陷，许多公司都研发出相关的广视角技术，而平面内切换技术就是其中颇具优势的一种。 In order to overcome the prior art liquid crystal device is a small viewing angle display defects, many companies have developed technologies related to the wide viewing angle, and wherein the in-plane switching technology is rather an advantage of. 请参考图1，是现有技术的平面内切换型液晶显示装置1的一像素区域P,其包括数据线115，与数据线115大致垂直的栅极线113,与数据线115大致平行的公共线135，薄膜晶体管（Thin Film Transistor, TFT) 120,公共电极133和像素电极13 1 。 Please refer to FIG. 1, a prior art in-plane switching type liquid crystal display device 1 of a pixel region P, which includes a data line 115, data line 115 is substantially perpendicular to the gate line 113, data line 115 is substantially parallel to the common line 135, a thin film transistor (thin film transistor, TFT) 120, a common electrode 133 and the pixel electrode 131. 该公共电极133包括公共电极弯折端133a与公共电极底端133b,该像素电极131包括l象素电极弯折端131a与^f象素电极底端131b。 The common electrode 133 includes a common electrode is bent end 133a and bottom common electrode 133b, the pixel electrode 131 includes a pixel electrode l is bent end 131a and bottom ^ f the pixel electrode 131b. 该^>共电极133与该/>共线135连接，该^象素电极弯折端131a与公共电极弯折端133a相互平行并交错排列，并且成折条形。 The ^> Total 135 is connected to the electrode 133 /> collinear, the bent end 131a ^ pixel electrode and the common electrode terminal 133a is bent parallel to each other and staggered, and to strip off. 该薄膜晶体管120设置在该数据线115与该栅极线113交界处，其包括分别与4册极线113、数据线115和<象素电极131连接的棚-极（未标示）、源极（未标示）、漏极（未标示）。 The thin film transistor 120 disposed in the data line 115 and the junction of the gate line 113, 113 which respectively include, Roofing and four data lines 115 and source lines <131 connected to the pixel electrodes - electrode (not shown), a source (not shown), a drain (not shown). 参考图2,是图1所示II区的放大图。 Referring to FIG 2, it is an enlarged view of the region II shown in FIG. 由于该像素电极弯折端131a与/^共电极弯折端133a为折线形，在加电压时，两者之间产生一双域电场，在该电场作用下液晶分子130沿两个方向偏转，使该像素在显示效果上被分成两个区域，在较倾斜方向观看时，该两区域引起的色差可相互补偿。 Since the bent end 131a of the pixel electrode / common electrode is bent end 133a ^ fold line, when a voltage is applied, an electric field is generated between one pair of the domain, liquid crystal molecules 130 deflect in both directions of the electric field at the the pixel is divided into two regions on the display, the more oblique direction when viewed, the two color region caused are compensated. 但是，在折线的弯折处，向叠加，该处的液晶分子130偏转方向不确定，不能正常偏转，使得光线不能正常通过，导致该平面内切换型液晶显示装置1辉度降低。 However, the bending of the fold line, the superimposed deflection direction of the liquid crystal molecules 130 where the uncertainty can not be properly deflected, so that light can not pass properly, resulting in the in-plane switching type liquid crystal display device of a decrease in brightness. 图3是图i所示in区的液晶分子偏转示意图。 Figure 3 shows the liquid crystal molecules in region i in FIG deflection FIG. 公共电极弯折端133a与像素电极底端131b是由相同材料构成并且在接近时不能短路，因此，公共电极弯折端133a尾端与像素电极底端131b 之间和像素电极弯折端131a尾端与公共电极底端133b之间必须留有空隙。 The common electrode and the pixel electrode 133a is bent bottom end 131b made of the same material and is not close to a short circuit, therefore, the bent end between the common electrode and the pixel electrode 133a trailing end 131b and the bottom end of the pixel electrode 131a is bent tail between the common electrode terminal 133b and the bottom must leave a void. 当施加电压时，在公共电极弯折端133a尾端与像素电极底端131b之间的电场141 a、 141b的方向以及〗象素电极弯折端131a尾端与公共电极底端133b之间的电场（图未示）方向不同于分布在l象素中部的电场140a、 140b方向。 When voltage is applied, the electric field between the common electrode and the pixel electrode 133a of the trailing end 131b is bent bottom ends 141 a, 141b direction, and the pixel electrode is bent〗 between the common electrode 131a and the rear end of the bottom end 133b an electric field (not shown) located in a direction different from 140a, 140b l central direction of the field pixels. 由于液晶分子具有朝液晶分子的长轴与电场方向间夹角较小的方向旋转的趋势，因此处于像素中部的所有液晶分子130c具有朝同一方向偏转的趋势，而处于公共电极弯折部133a尾端与像素电极底端131b之间以及像素电极弯折部131a尾端与公共电极底端133b之间拐角处的液晶分子130a、 130b朝相对的方向偏转（如图3实心箭头所示），即该处的液晶分子130a、 130b与像素中部的液晶分子130c偏转方向不同，透射特性也不同，因此该拐角区域出现暗带。 Since the liquid crystal molecules with an electric field between the major axis direction of liquid crystal molecules in relatively small angle with the direction of rotation of the trend, and therefore the liquid crystal molecules in the middle of all the pixels 130c has a tendency to deflect in the same direction, and the bent portion 133a at the end of the common electrode between the bottom end of the pixel electrode 131b and the liquid crystal molecules at the corner of the bent portion 131a between the pixel electrode and the common electrode is the bottom end of the trailing end 133b 130a, 130b deflects the opposite direction (solid arrow shown in FIG. 3), i.e., where the liquid crystal molecules 130a, 130b and the deflection direction of the central pixel of the liquid crystal molecules 130c different transmission characteristics are different, so that the corner region appears dark bands. 综上所述，该弯折形电极结构的平面内切换型液晶显示装置1具有图2所示的弯折部分以及图3所示的拐角区域两处缺陷。 In summary, a bending plane of the electrode structure of the switching type liquid crystal display device 1 having a bent portion and two corner region shown in FIG defect 2 shown in FIG. 为克服上述缺陷，业界对电极结构进行了改进，请一并参阅图4至图6。 To overcome the above drawbacks, the industry has been improved electrode structures, Referring to FIG. 4 to FIG. 6. 图4是改进的平面内切换型液晶显示装置2的电极结构示意图。 FIG 4 is a plane-type liquid crystal display improved switching device 2 a schematic view of the electrode structure. 该像素电极233包括像素电极底端233b与像素电极弯曲端233a，该7>共电极243包括公共电极底端243b与公共电极弯曲端243a。 The pixel electrode 233 includes a bottom end of the pixel electrode and the pixel electrode 233b curved end 233a, the 7> comprises a common bottom electrode 243 and the common electrode common electrode 243b curved end 243a. 该像素电极弯曲端233a和公共电极弯曲端243a 形状为波浪形，其间形成的电场方向为连续变化，即连续域，因此该结构可以称作为连续域结构。 The bent end 233a of the pixel electrode and the common electrode wavy electric field direction is formed therebetween, a continuous change, i.e. continuous domain shape curved end 243a, so that the structure may be referred to as a continuous domain structure. 此种电极结构克服了图2所示弯折形电极结构中液晶分子在弯折部分不正常偏转造成辉度低的现象。 Such an electrode configuration overcomes a bending phenomenon of the electrode structure of the liquid crystal molecules in the abnormal deflection of the bent portion causes a low luminance as shown in FIG. 图5是图4中V区所示施加电压时电场以及液晶分子偏转示意图。 FIG 5 is a view of an electric field applied voltage is shown in FIG. 4 and the V region of the liquid crystal molecules are tilted FIG. 像素电极弯曲端233a与公共电极弯曲端243a平行。 The bent end 233a of the pixel electrode and the common electrode parallel to the bent end 243a. 在像素电极233与/>共电极243施加电压时产生一电场290。 Generating a field 290 a voltage is applied to the pixel electrode 233 /> 243 common electrode. 此时在该/>共电极底端243b与/>共电极弯曲端243a尾端所成的锐角a 与该像素电极弯曲端233a尾端与公共电极底端243b所成的钝角P周围电场出现旋转扭曲变形。 In this case the /> common electrode 243b and the bottom /> 243a trailing end of the common electrode is bent at an acute angle formed by a bent end of the pixel electrodes 233a and trailing end 243b of the common electrode to the bottom end of the electric field appears at an obtuse angle of rotation around the P distortion. 施加电压时处于平行电场区域中的液晶分子230a顺时针方向旋转，而处于扭曲电场区域中的液晶分子230b反时针旋转，即处于平行电场和扭曲电场中的液晶的取向不同，扭曲电场区域由此产生暗带，引起开口率降低。 When a voltage is applied to the liquid crystal molecules parallel to the electric field in the region 230a in a clockwise direction, while the liquid crystal molecules is twisted in the field region 230b rotates counterclockwise, i.e., in the parallel electric field and different twisted alignment of liquid crystal in an electric field, thereby distorting the electric field region a dark band, causing aperture ratio. 这些缺陷也会影响液晶层的反应特性，使显示区域出现残余影像。 These defects also affect the response characteristics of the liquid crystal layer, residual image appears in the display area. 图6是该种弯曲形电极结构施加电压时的光学效果图。 FIG 6 is a view of an optical effect of a voltage applied to the electrode kind of curved configuration. 该图中四个亮区域所示为液晶层，第一亮区al与第二亮区a2之间以及第三亮区a3与第四亮区a4之间分别存在一条亮线p，是像素电极；第二亮区a2与第三亮区a3之间存在一条暗线c,是公共电极。 The figure shows the relationship between the liquid crystal layer, the first light and the second region al bright area a2 and the third area a3 and the presence of light, respectively, between the bright region a4 fourth p a bright line four bright regions, the pixel electrode is ; c presence of a dark line a2 second bright region and the third region between the bright a3, is a common electrode. 请一并参阅图4至图6，该图6中两个虚线圆框内的部分为电极尾端区域处形成的暗区。 Referring to FIG. 4 to FIG. 6, FIG. 6 in the two dashed circle dark box portion of a region of the electrode region formed trailing end. 可以看出，施加电压时该区域的光透过率下降。 As can be seen, the light transmittance of the region of the applied voltage drops. 综上所述，该种弯曲形电极结构的平面内切换型液晶显示装置2解决了弯折形电极结构的平面内切换型液晶显示装置1中电极弯折部液晶分子偏转不正常的问题，但是对于电极尾端出现的扭曲电场问题仍未能很好的解决。 In summary, the plane of the electrode structure of the kind of curved liquid crystal display device 2 is switched to solve the structure of a plane-shaped electrode bent switching type liquid crystal display device of the bent portion of the liquid crystal molecules in the electrode a deflection is not working properly, but distorted electric field to the electrode end of the problem appears still not a good solution.

Please refer to FIG. 7 to FIG. 9, device 3 is a schematic view of a first embodiment of the present invention, the in-plane switching mode liquid crystal display. 与现有技术平面内切换型液晶显示装置结构相似，该平面内切换型液晶显示装置3包括相对设置的第一基底（图未示）与第二基底（图未示），置于第一基底与第二基底间的液晶层（图未示），多个设置在该第一基底上并且相互垂直的栅极线311和数据线312，多个设置在该栅极线311与该数据线312交叉处的薄膜晶体管320, ^象素电极330和公共电极340。 Similar apparatus structure, this plane switching type liquid crystal display and switches within the prior art flat-type liquid crystal display device 3 comprises a first substrate (not shown) disposed opposite the second substrate (not shown), a first substrate disposed the liquid crystal layer (not shown) between the second substrate, a plurality of settings on the first substrate and the gate line 311 perpendicular to each other and the data lines 312, a plurality of gate lines disposed on the data line 311 and the 312 at the intersection of the thin film transistor 320, the pixel electrode 330 ^ 340 and the common electrode. 该像素电极330包括像素电极弯曲部333和像素电极底端332，该公共电极340包4舌/>共电才及弯曲部343和/>共电才及底端342。 The pixel electrode 330 includes a pixel electrode 333 and the pixel electrode curved bottom portion 332, the common electrode 340 for 4 lingual /> was co-electroporated and bending portions 343 and /> was co-electroporated and a bottom end 342. 该像素电极330与公共电极340相应于该像素区域设置，在本实施方式中其均设置于第一基底上，该像素电极弯曲部333与该公共电极弯曲部343相互平行并交错排列，并且是由至少两个弧形结构组成的平滑曲线，其间形成的电场方向为连续变化，即连续域，因此该结构可称作为连续域结构。 The pixel electrode 330 and the common electrode 340 corresponding to the pixel region is provided, which in the present embodiment are disposed on the first substrate, the pixel electrode 333 parallel to each other and the bent portions of the bent portions 343 and the common electrode alternately arranged, and is smooth curve by at least two arc-shaped structures, the direction of the electric field formed therebetween is continuously changed, i.e. continuous domain, so that the structure may be referred to as a continuous domain structure. 图8是图7所示VIII区的电场和液晶分子偏转示意图。 Field region VIII shown in FIG. 7 and FIG. 8 is a schematic view of the liquid crystal molecules are tilted. 相对于图4所示的电极结构，其不同之处在于：在公共电极弯曲部343 与公共电极底端342的连接处设计一倒角342a,该倒角342a与7>共电极弯曲部343和7>共电极底端342材质相同并且是一整体。 The electrode structure shown in FIG. 4 with respect to which except that: the design of a chamfer 342a of the common electrode 343 and the curved portion is connected at the bottom end of the common electrode 342, and the chamfer 342a 7> common electrode 343 and the bent portion same 7> material of the common electrode 342 and the bottom end is integral. 且该倒角342a位于公共电极弯曲部343在该连接处的切线方向与公共电极底端342所成的锐角一侧（图5中所示的锐角a处）并且凸出/>共电才及底端342,即为内倒角。 The acute angle side (at a acute angle as shown in FIG. 5) and the chamfered curved portion 342a of the common electrode 343 is located at the bottom end of the tangential direction at the connection to the common electrode 342 and the projection /> only electrically common and the bottom 342, that is, within the chamfer. 在该种电^?l结构下，倒角342a的外侧边缘与公共电极弯曲部343以及像素电极弯曲部333 垂直。 In this kind of electric ^? L In the structure, the chamfered outside edge 342a of the common electrode and the pixel electrode 343, and the bent portion 333 bent portion perpendicularly. 当在公共电极340与像素电极330施加电压时产生电场390，该电场390垂直于像素电极弯曲部333与公共电极弯曲部343，且在倒角342a附近的电场也为均匀分布的连续电场，无扭曲电场现象出现。 390 generating an electric field when voltage is applied the common electrode 340 and the pixel electrode 330, the electric field perpendicular to the pixel electrode 390 bent portion 333 bent portion 343 and the common electrode, and an electric field in the vicinity of the chamfer 342a is also uniform distribution of the electric field as a continuous, non- distorted electric field phenomenon. 在像素电极弯曲333与像素电极底端332的连接处也有同样设计的倒角332a(参阅图7)。 At the bottom of the pixel electrode and the pixel electrode 333 is bent at the connection 332 has the same design chamfer 332a (see FIG. 7). 由图中看出，远离倒角342a的液晶分子303a顺时针旋转，邻近倒角342a的液晶分子303b也顺时针旋转，因此，在该电场下，相同的旋转方向避免倒角342a附近的扭曲电场以及暗带的出现，液晶层的反应特性提高，显示区域也无残余影像。 Seen from the figure, the liquid crystal molecules 342a away from the chamfer 303a is rotated clockwise, the liquid crystal molecules adjacent to the chamfer 342a 303b is also rotated clockwise, therefore, the electric field in the same direction of rotation to avoid distortion of electric field near the chamfer 342a and response characteristics appear dark band liquid crystal layer is increased, the image display region and no residue. 图9是该电极结构在施加电压下的光学效果图。 9 is a structure of the electrode at an applied voltage of the optical effect of Fig. 与图6类似， 该图中四个亮区所示为液晶层，第一亮区bl与第二亮区b2之间以及第三亮区b3与第四亮区b4之间分别存在一条亮线pl，是像素电极；第二亮区b2与第三亮区b3之间存在一条暗线cl,是公共电极；两个虚线圆框内的部分为电极尾端的多余域处形成的暗区。 Similar to FIG. 6, which is shown in four bright area liquid crystal layer, respectively, exist between the first light b4 between the bright region and the second region bl b2 b3 bright region and the third region and the fourth light of a bright line pl, is a pixel electrode; bright region is present between the second and the third light area b3 b2 a dark line cl, is a common electrode; two dotted circle box formed part of the dark area of the electrode domain excess trailing end. 与前述图6对比可以看出，像素电极所在的亮线pl的亮度有所提高，公共电极所在的暗线cl的亮度也有显著提高，并且，因<象素电极弯曲部与<象素电极底端，/〉共电才及弯曲部与/>共电才及底端的电场扭曲而产生的暗带现象也有明显改善，说明该处倒角的引入改善了液晶分子在该处的旋转方向，使整个电场方向趋向均一，该处的光透过率有明显提高，显示特性得到明显改善。 Comparative foregoing it can be seen in FIG. 6, the luminance of the bright lines pl where the pixel electrode is improved, the luminance of the dark line cl where the common electrode is also significantly improved, and, because the bottom end <the pixel electrode and the bent portion <the pixel electrode , /> and the total was bent portion and electrically /> was co-electroporated and bottom field distortion phenomenon is generated dark bands have improved greatly, improved chamfered described where the introduction of liquid crystal molecules in a direction where the rotation of the entire the tendency of a uniform electric field, where the light transmittance is improved significantly, the display characteristics are improved. 由于不仅消除了现有技术中弯折形电极结构中双域交界处电场异常，而且消除了像素电极与连接线以及公共电极与公共线的连接处多余域的电场异常及其产生的液晶分子偏转异常，因此现有技术中的透光率较低的情形得以避免，从而能达到较高的辉度。 Since not only the elimination of the prior art folding type electric double domain structure of the electrode junction abnormalities, but also eliminates the pixel electrode of the liquid crystal molecules and the electric field lines and is connected at the extra-domain common electrode is connected to the common line and the resulting deflection of an abnormality abnormal, so the prior art low light transmittance situation is avoided, so that it can achieve high luminance. 本实施方式中，该数据线312也可为平滑曲线，与像素电极弯曲部333平^f亍。 In the present embodiment, the data line 312 may also be a smooth curve, the curved portion 333 and the pixel electrode flat ^ f right foot. 本发明平面内切换型液晶显示装置的公共电极与像素电极对应每一像素区域，其可以设置于不同基底上，并产生近似平行的电场，即该电场的主要分量在与基底平行的方向上；当设置在同一基底时，可以有如钝化层等隔离层存在于其间，而使二电极位于不同层；或将公共电极与像素电极置于同一层以产生平行性更优的电场。 The common electrode and the pixel electrode corresponding to each pixel within the plane area of the present invention, the switching liquid crystal display device, which may be disposed on different substrates, and an electric field approximately parallel, i.e., in a direction parallel to the substrate main component of the electric field;
