Description of the invention (,) The present invention relates to a liquid crystal display device, especially an active matrix liquid crystal display device suitable for the horizontal electric field method, which can effectively improve manufacturing Yield, to achieve the purpose of fewer afterimages, wide viewing angles and high-quality portraits. The conventional active matrix liquid crystal display device is formed by comb-shaped electrodes on one substrate to form a liquid crystal composition layer on the substrate. For example, Japanese Patent Laid-Open No. 7-36058 and Japanese Patent Laid-Open No. 7-1 59786 both use this method. The display mode in which the main electrical interface direction and the substrate interface are approximately parallel is called the horizontal electrical interface mode, as shown in the first and second figures, that is, the aforementioned liquid crystal display device of the horizontal electrical interface mode is mainly based on a glass substrate ( 1 〇) The surface is provided with a cat fe line (1) and a common electrode (3). An insulating film (5) is provided on the upper layer of the two, and an image signal wiring (2) is provided on the insulating film (5). , A semiconductor layer (T) and a liquid crystal driving electrode (4), and an insulating film (6) is provided on the three above, and the insulating film (6) is sequentially provided with a TFT-side alignment film (7) and liquid crystal molecules (9) ), A counter substrate-side alignment film (8), a counter glass substrate (1 1), a counter substrate-side polarizing plate (1 2), and the like. The aforementioned common electrode (3) and the liquid crystal driving electrode (4) are arranged on different layers, but are arranged in a straight and parallel comb shape, and the scanning signal line (1) and the image signal wiring (2) are also straight. Comb-like arrangement. The common electrode (3) and the video signal wiring (2) are not overlapped, and the common electrode (3) and the liquid crystal drive electrode (4) are interposed between the insulating film (5) to form a compensation capacitor. Another common electrode (3) and LCD driver which occupy nearly half of the pixel area. This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) ----------- (Please read the back first (Notes on this page, please fill in this page), Ϊ 494265 Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (j) The surface of the electrode (4) is covered with a self-oxidizing film or self-nitriding to prevent short circuit. membrane. As for the liquid crystal display device of the transverse electric boundary type mentioned above, since the scanning signal line (1) and the common electrode (3) are formed on the same layer, the probability of short circuit between the two is quite high. Similarly, the image signal wiring (2 ) And the liquid crystal driving electrode (4) are also formed on the same layer, so there is also a problem that it is easy to cause a short circuit. When the scanning signal line (1) and the common electrode (3) are short-circuited, a horizontal line defect will be caused; and when the image signal wiring (2) and the liquid crystal drive electrode (4) are short-circuited, a point defect will be caused, which will significantly reduce the image quality Therefore, it is difficult to improve its yield in manufacturing, and it will increase the production cost. In the transverse electric boundary method, if no compensation capacitor is formed, the capacity of the liquid crystal drive electrode (4) is very small, and the leakage current of the TFT thin-film transistor is leakage. The non-uniformity will cause the non-uniformity of the entire screen, and it is easy to see the non-uniformity of the screen. Therefore, in the conventional technology, the common electrode (3) and the liquid crystal driving electrode (4) are formed through an insulating film (5). On different layers, they are still overlapped with each other. However, if a large compensation capacitor is to be formed, the effective screen can only be reduced to enlarge the area of the overlapped portion, which causes the main cause of poor light transmittance. As shown in the second figure, the common electrode (3) and the liquid crystal drive electrode (4) are arranged in a comb-like arrangement in a straight line, that is, as described in the transverse electrical boundary method, in terms of the transverse electrical boundary method, the pretilt angle (Pre -tilt angle) will greatly change the viewing angle of the liquid crystal display device into a known technique. Therefore, in order to obtain the ideal viewing angle characteristics in the horizontal electric field method, a pre-paper size of 4 papers is applicable to the Chinese National Standard (CNS).

Description of the invention (3) Alignment film with very small inclination Experiments with liquid crystals are shown in Figure 24A, and the pretilt angle of the alignment film in the transverse electrical boundary mode is expected to be 1 degree or less (the one shown in the figure is 0.8 degrees). However, it is also currently used for mass production of the longitudinal electrical boundary method. The pretilt angle between the alignment film and the liquid crystal is between 3 and 8 degrees (as shown in Figure 24, the expected value is 3.3 degrees). In the longitudinal electrical boundary method, if an alignment film and liquid crystal having a pretilt angle of 1 degree are used, a reverse tilt domain will be generated due to the influence of the image signal line and the pixel electrode. This reverse tilt region will make the liquid crystal The image quality of the display device is significantly reduced. From the above, it can be known that it is difficult to use the liquid crystal display device of the vertical electric field type and the liquid crystal display device of the horizontal electric field type to use the same pretilt alignment film and liquid crystal. Therefore, the horizontal electric field type and the vertical electric field type are produced by the same manufacturing equipment When a liquid crystal display device is used, different alignment films and liquid crystals must be replaced, which seriously affects production efficiency.

Description of the invention (V) As mentioned above, conventional In the horizontal electric field method, the common electrode (3) and the liquid crystal drive electrode (4) occupy a large effective screen, resulting in a low aperture ratio. Even if it is properly designed, the aperture ratio does not reach about 50%, and its effective area is nearly half. It is occupied by the common electrode (3) and the liquid crystal drive electrode (4). In the conventional technology, since no anti-reflection film is formed on the surface of these electrodes, the liquid crystal layer is penetrated by a color filter when it enters from the outside. The light is reflected from the surface of the common electrode (3) and the liquid crystal drive electrode (4), and is emitted through the color filter again. In this state, the black level will move to the gray band (that is, the black tone will appear gray), so the black tone of the entire screen will be inferior to the liquid crystal display device of the previous vertical mode.

The description of the invention (r) and the liquid crystal drive electrodes exist on different layers through the insulating film, which can effectively reduce the short circuit between the scanning signal line and the common electrode And reduce the horizontal line defects of the screen; moreover, the probability of short circuit between the image signal wiring and the liquid crystal drive electrode is also reduced, which can reduce the point defects of the screen. A second object of the present invention is: at least a part of the video signal wiring and its common electrode or at least a part of the scanning signal line and its common electrode are overlapped with each other through an insulating film therebetween; At least a part of the aiming signal line and the common electrode are overlapped with each other through an insulating film therebetween, and a compensation capacitor is formed in the overlapping portion. In the aforementioned design, a part of the common electrode, the image signal wiring, and the scanning signal line are overlapped with each other through the insulating film therebetween, so as to enlarge the aperture ratio of the liquid crystal display device; and at least the liquid crystal driving electrode, the scanning signal line and the common electrode are at least A part of the compensation capacitor formed by overlapping the insulating film can be increased, thereby preventing poor image quality due to the low cut-off resistance of the thin film transistor, and the large compensation capacitor can also reduce the scanning signal line. The generated liquid crystal driving voltage fluctuation phenomenon can prevent the afterimage of the screen from being generated. Another object of the present invention is: when the aforementioned image signal wiring and pixel electrode (a part of the common electrode opposed between the liquid crystal driving electrodes) adopts positive-attractivity anisotropic liquid crystal (P-type LC), Relative tortuosity angle is within the range of ± 1 to ± 45 degrees; when the aforementioned scanning signal lines and pixel electrodes use positive-attractivity anisotropic liquid crystal (P-type LC), the relative tortuosity angle between the two and the liquid crystal molecules For 7 paper sizes, the Chinese National Standard (CNS) Α4 specification (210 X 297 mm) is applied (please read the notes on the back 1 · Items and then fill in—: write this page) Order the staff of the Central Standards Bureau of the Ministry of Economic Affairs Cooperative printed A7 B7 V. Description of the invention (me) range of soil 1 to soil 45 degrees; when the aforementioned image signal lines and pixel electrodes use negative-attractivity anisotropic liquid crystal (N-type LC), it is related to liquid crystal molecules The relative tortuous angle is in the range of 45 to 135 degrees other than 90 degrees; when the aforementioned scanning lines and pixel electrodes use negative-attractivity anisotropic liquid crystal (N-type LC), the relative to the liquid crystal molecules Zigzag angle is 45 other than 90 degrees In the range of 135 degrees;-Through the aforementioned design, when the horizontal electrode boundary is imprinted in the pixel electrode, the liquid crystal molecules generate two rotational movements, left and right, inside the pixel electrode. Thus, even if the pretilt angle is large, the viewing angle characteristics are not Be biased. From this, it can be seen that the liquid crystal display device of the present invention is not limited by the pretilt angle. Therefore, the degree of freedom in selecting the alignment film and the liquid crystal becomes larger, in other words, it is easy to improve the afterimage and the response speed. It can also be used, and its production efficiency can naturally be improved, the effective utilization rate of the polarizing plate can also be increased, and the production cost can be reduced accordingly. Another purpose of this creation is to form an anti-reflection film layer on the surface of two or at least one of the aforementioned liquid crystal driving electrodes and common electrodes. With the aforementioned design, when light enters from the outside and passes through a color filter, and The intrusion into the liquid crystal layer will be eliminated due to the formation of an anti-Xie film on the upper layer of the common electrode and the liquid crystal drive electrode. As a result, the black tone can be improved, the contrast can be improved, and high-quality images can be easily viewed. In addition, the liquid crystal display device constituted by the main purpose and the second purpose of the present invention is applicable to the Chinese paper standard (CNS) A4 specification (210X 297 mm) from the 8 paper sizes of the backlight (BACK LIGHT) other than the effective pixels.

Description of the invention (7) Light leakage will be reduced, so the size of the filter can be reduced. In the black photomask (BM) field, and the thin film transistor can be completely covered by a part of the common electrode or a part of the liquid crystal driving electrode, the semiconductor active layer of the thin film transistor is not directly exposed to external light. Therefore, the thin film transistor is cut off. The light leakage current can be effectively reduced. In the past, any filters that were necessary in the past can be made unnecessary. This can shorten the manufacturing process of color filters. Since the yield can be improved, the production cost can also be reduced. -In order to make your reviewers better understand the foregoing objectives and specific method features of the present invention, detailed drawings are attached as follows: (I) Schematic part: Figure 1: A cross-sectional view of a unit pixel of the conventional horizontal electrical boundary method .

於直條狀的液晶驅動電極（4 )及共通電極的長邊方向持 有若干角度（1至4 5度）之配向，又，與上下基板的界 面部的液晶分子（9 )之配向互相平行，當液晶分子（9 )的誘電率異方性爲正，使用負的誘電率異方性之液晶分 子（9 )時，液晶分子（9 )配向方向之軸（P)與畫素 電極（4)(3)的交叉角度設定在45〜89度之間即 可。 又於前述之第一實施例中，如第三圖所示之共通電極

)不可與共通電極（3 )重疊，亦可與掃瞄信號線（1 )重疊，因此，可以在不降低開口率的前提下，大大提高 補償電容。再如第卅七、卅八圖所示，該液晶驅動電極（ 4 )可以將薄膜電晶體T F T的非晶質矽能動層（T )完 全覆蓋，又如第卅一、卅五、卅六圖所示，令共通電極（ 3 )的一部分與掃瞄信號線（1 )或影像信號配線（2 ) 重疊，可以大幅減少從有效畫素以外所漏出來的光。 又如第六至十圖所示，爲本發明第二較佳實施例，其 主要係於一玻璃基板（10)上先形成掃瞄信號線（1) ，又於掃瞄信號線（1 )上進行陽極氧化處理，而覆蓋形 成陽極氧化膜（17)，該陽極氧化膜（17)可由鋁、 鈦、鈮等金屬或其合金處理，另積層構造的閘極電極亦可 〇 又完成陽極氧化膜（1 7 )後，仍於玻璃基板（1 0 )上形成共通電極（3)，隨後於前述構造上形成完全覆

，該玻璃基板（1 0 )於其上形成掃瞄信號線（1 )(閘 極電極），及覆蓋該掃瞄信號線（1 )之絕緣膜（5 )後 ，即於絕緣膜（5 )上形成非晶質矽膜構成之電晶體能動 層（Τ )，隨後形成與該能動層（Τ )部分接觸之影像信 號配線（2 )及集極電極（D)及覆蓋前述各構造之絕緣 膜（6)，接著，於絕緣膜（6)上對應於該集極電極（ D )處形成有穿孔（1 5 )及液晶驅動電極（4 )，該液 晶驅動電極（4 )即經由穿孔（1 5 )與集極電極（D ) 接觸並構成電氣連接，隨後再形成上層絕緣膜（2 1 )將 前述各者完全覆蓋。 再於前述構造所組成單位畫素呈矩陣狀配置的主動式 矩陣型基板表面設有一配向膜（7)，該配向膜（7)係 由Ρ I (POLY-IMIDE)所構成，其表面實施有配向處理（ RUBBING )，又配向膜（7 )表面形成有另一配向膜（

緣隔離，所以如第十五圖所示，其二者可以相互重疊’該 重疊部分並可供形成補償電容。更如第十六圖所示’該液 晶驅動電極（4 )不僅可與共通電極（3 )重疊’亦可與 掃瞄信號線（1 )重疊。因此，可以在不降低開口率的前 17 本紙張又度適用中國國家標準（CNS ) A4規格（210 X 297公釐） 494265 A7 B7 五、發明説明（名） 提下，大大提高補償電容。再如第卅九至四二圖所示，該 液晶驅動電極（4 )或共通電極（3 )可以將薄膜電晶體 TFT的非晶質矽能動層（T)完全覆蓋，又如第卅二至 卅四圖所示，令共通電極（3 )的一部分與掃瞄信號線（ 1 )或影像信號配線（2 )重疊，可以大幅減少從有效畫 素以外所漏出來的光。因此可不須使用黑光罩的彩色濾光 片。 再如第四三、四四圖所示，本實施例中可以除去有效 畫素內液晶驅動電極（4 )表面所形成之上層絕緣膜（2 1 )，而形成有開窗（W ) (OPEN WINDOW)。因此，液 晶驅動電極（4)及共通電極（3)表面可直接形成配向 膜（7 )。由於液晶基本上是由交流電驅動，如果被印加 上直流成分之柵極偏壓（BIAS VOLTAGE)時，會有配向膜 (7)的分極、且配向膜（7)與絕緣膜（21)之界面 出現電荷捕捉（CHARGE TRAP)現象，而於畫面上出現殘 像，於本實施例中，兩方的電極直接接觸到配向膜（7)
