Description

1329218 99-2-26 IX. Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display (LCD) and, in particular, to a compensation offset (Biased Compensation) The manner in which the spacer has a uniform pressing density of the liquid crystal display panel. [Prior Art] The liquid crystal display panel is usually composed of a thin film transistor array substrate (Thin

The Film Transistor Array Substrate (TFT array substrate) is composed of a color filter substrate (CF substrate). In order to fill a liquid crystal layer between the thin film transistor array substrate and the color filter substrate, it is necessary to maintain a certain gap between the substrates by using spacers. Usually, the spacer is disposed on the color filter substrate and abuts against the thin film transistor array substrate. However, in the process of assembling the liquid crystal display panel, the spacers are shifted due to the shift of the panel, so the area density (i.e., the stamping density) of the spacers contacting the thin film transistor array substrate changes. Therefore, the gap between the two substrates will be uneven, resulting in poor display of the panel. In view of the above, two methods of shift stopping and biased compensation have been proposed in the prior art to improve the problem of poor display of the panel due to the offset of the spacer. 1A and 1B are schematic cross-sectional views showing two conventional liquid crystal display panels. Referring first to the drawings, the liquid crystal display panel 100 includes a thin film transistor array substrate 11 and a 1329218 99-2-26: a color filter substrate 120 and a liquid crystal layer 13 between the two substrates. Further, the thin film transistor array substrate 110 has a plurality of protrusions 112, and a recess 114 between the protrusions 112. It is to be noted that the gap 140 is disposed on the color filter substrate 12A and abuts against the recess Π4 to prevent the spacer 14 from moving. - ° Referring again to FIG. 1B, the liquid crystal display panel 200 also has a thin film transistor array substrate 210, a color filter substrate 220, and a φ liquid crystal layer 230 between the two substrates. The thin film transistor array substrate 210 has a drain 212 thereon, and the flat layer 216 covers the drain 212. The contact opening 216a is formed in the flat layer 216 above the drain 212, and the pixel electrode 214 is electrically connected to the drain 212 via the contact opening 216a. It is to be noted that the spacer 240 is disposed on the color filter substrate 22 and is inserted into the contact opening 216a to prevent the spacer 240 from moving. By preventing the offset as shown in Fig. 1A or Fig. 1B, the gaps 140, 240 can be prevented from moving and preventing panel offset. However, since the force is generally larger when the panel is offset, the spacers 140, 240 are still pushed out of the recessed portion 114 or the contact window opening 216a, causing poor support of the spacers 14 and 240 and unevenness of the gap d. problem. Further, Fig. 2A is a schematic cross-sectional view showing another conventional liquid crystal display panel. The liquid crystal display panel 300 has a plurality of spacers 344 and 342 (only one is shown) on the thin film transistor array substrate 31 and the color filter substrate 320, and partially abuts between the spacers 344 and 342. And maintaining the gap d of the panel, and distributing the liquid crystal layer 330 between the two substrates. - Figure 2B is a top plan view of the spacer of Figure 2A. In addition, when the color filter substrate 32 is shifted to the right, the contact area R1 between the spacer 342 and the spacer 344 in the spacer group A1 becomes small, but The contact area 342 in the second spacer group A2 and the contact area R2 of the object M4 become large, so that the contact surface between the first spacer group A1 and the second spacer group A 2 can be made on the horizontal side 1, R2 compensates each other. According to the same principle, the contact areas between the second spacer group A3 and the fourth spacer group A4 can be mutually compensated in the vertical direction. However, the liquid crystal display panel 300 as shown in FIG. 2A and FIG. 2B is only applicable to the case where the panel offset is not large, that is, the panel offset is only less than half of the spacers 342 and 344. Within the scope of. As the trend of large-sized panels progresses, the panel offset must increase. At this time, the above method will fail, and still cause problems such as uneven density of the spacers, unevenness of the gap, and poor display of the panel.

The third compensation spacer 570c is spaced apart from the first protrusion 590 on the second horizontal wire 520b in the second region 510b by a third distance D. The fourth compensation spacer 570d is located The first protrusion 590 on the second horizontal wire 520b in the third area 510c is spaced apart from the fourth distance E. The offset distance of the main spacer 560 in the Y direction is greater than the fourth distance 1329218 99-2-26 E is less than the sum of the fine distance E and the visibility W4 of the fourth compensation (10) object in the γ-axis direction. The fourth compensation gap 57 〇d abuts the second horizontal wire 52 in the third region 510c. The first protrusion 59 on b is placed on the A to reduce the abutment area between the main spacer 560 and the outer protrusion j on the second horizontal conductor 52〇b to be equal to the fourth compensation spacer $7. The increased abutment area between 〇d and the first protrusion 590 on the second horizontal wire 520b in the third region 51〇C. When the offset distance of the two main spacers 560 to the +Y direction is greater than the third distance D and less than the sum of the third distance D and the third compensation gap edge itself on the Y-axis, the upward width W3, the third compensation spacer 5 sighs against the first protrusion on the second horizontal wire 52〇b in the second region 510b, causing the main spacer 560 to rise from the second dog on the second horizontal wire 52〇b. The reduced abutment area between the turns 590 is equal to the increased abutment area between the third compensation gap 570c and the first raised portion 590 of the second horizontal wire in the second region 51〇b. As described above, when the vertical shift amount of the liquid crystal display panel 502 is small, the main spacer 560 itself has a compensation value of the fourth distance E in the -γ direction and the second distance D in the += direction. However, when the vertical offset 塁 of the panel is greater than the second distance D or the fourth distance E, the liquid crystal display panel 502 of the above design can also compensate the vertical offset of the panel to be “W3 + D” or “W4 + E”. Within the scope. Further, since the first compensation gap 57a and the second compensation spacer 570b' are also provided at the same time, the liquid crystal display panel 5〇2 can allow a larger panel shift amount in both the horizontal direction and the vertical direction. Even if the offset of the panel is large, the liquid crystal display panel 502 can obtain a uniform gap density and panel gap of the 24 1^29218 99-2-26 gap, thereby obtaining good display enable. - It is worth mentioning that 'because it is the Liehe layer 54G Cheng-protrusion 590 590 ' so the position of the first-protrusion can be set to a better compensation offset effect. In addition, the pad layer 540 of this embodiment may also be a film layer in a thin film transistor (shown) such that the thin film transistor itself protrudes to form the first toe portion 590. Therefore, as described above, the main gap 560 can be abutted against the first protrusion 59 一个 of a thin film transistor, and a compensation gap 57 设置 is provided around the main spacer 560 for horizontal and vertical directions. Compensation offset on. ° Red, the liquid crystal display panel of the present invention has the following advantages: The main spacers and the compensation spacers of the present invention can compensate for a large panel offset in the horizontal direction and the vertical direction, and further It can maintain uniform gap pressing density and panel gap. In addition, the degree of freedom in setting the first protrusion can be improved by the enamel layer, thereby improving the effect of compensating for the offset. Since the liquid crystal display panel of the present invention has a uniform gap and the valley is susceptible to panel shift, the liquid crystal display panel of the present invention will have good display performance. Although the present invention has been disclosed in the above preferred embodiments, the present invention is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit of the invention.
