However, since the color filter layer 216 is formed confiormally on the stacked film of the active device array substrate 210, the thickness variation Δc2 of the color filter layer 216 (shown in figure 2 ) will be compared with the thickness variation Δc1 of the color filter layer 126 (shown in figure 1 ) come big
In other words, in figure 2 In the liquid crystal display panel 200 (that is, the COA structure), when the deviation of the distance D2 (that is, the sum of △a2, △b2, and △c2) increases beyond the allowable range of liquid crystal droplet volume (LC margin), it will cause the liquid crystal layer 230 injection failure, thereby affecting the manufacturing yield and display quality of the liquid crystal display panel 200

[0080] Figure 4A is a schematic cross-sectional view of a liquid crystal display panel according to another embodiment of the present invention, and Figure 4B for Figure 4A A top view of a liquid crystal display panel. Please refer to Figure 4A and Figure 4B , the liquid crystal display panel 400 of this embodiment and Figure 3A as well as Figure 3BThe liquid crystal display panel 300 has a similar structure, and similar and identical symbols represent similar and identical components, but the difference between the two lies in that each opening W of the liquid crystal display panel 400 is respectively located in one of the color filter layers 316 ′. In the filter pattern (316A', 316B' and 316C'). In this embodiment, the opening W is located on the scan line 11b, for example. For ease of illustration, Figure A4 and Figure 4B It is only shown that the opening W is located in the red filter pattern 316a, but the embodiment is not limited thereto.

Description

technical field [0001] The present invention relates to a display panel, and in particular to a liquid crystal display panel. Background technique [0002] The rapid progress of the multimedia society is mostly due to the rapid progress of semiconductor components or man-machine display devices. As far as the display is concerned, the cathode ray tube (Cathode Ray Tube, CRT) has been monopolizing the display market in recent years because of its excellent display quality and economical efficiency. However, for the environment where individuals operate most terminals / display devices on the table, or from the perspective of environmental protection, if the trend of energy saving is used to predict that cathode ray tubes still have many problems in terms of space utilization and energy consumption, and for The demands of lightness, thinness, shortness, smallness and low power consumption cannot effectively provide a solution. Therefore, thin film transistor liquid crystal dis...
