[0065] Figure 4A It is a three-dimensional schematic diagram of the color filter substrate for completing the black matrix in the first embodiment of the present invention. Figure 4B From Figure 4D to Figure 4A Sectional view of subsequent manufacturing process. Please refer to Figure 4A Firstly, a substrate 400 with a plurality of pixel regions 402 is provided, and a plurality of striped patterns 412 are formed between these pixel regions 402 to form a black matrix 410 on the substrate 400 .

[0066] It should be noted that the color filter patterns (not shown in the figure) formed in the subsequent manufacturing process are arranged in these pixel regions 402 . Those skilled in the art should know that most of the subsequently formed color filter patterns include red filter patterns, green filter patterns and blue filter patterns, and the arrangement of these filter patterns on the substrate 400 can be The mosaic type, triangle type, stripe type or four pixel type ar...

[0081] Figure 9A to Figure 9D These are the cross-sectional views of the manufacturing process of the color filter substrate in the second embodiment of the present invention in sequence. It is worth noting that the black matrix formed by the method of this embodiment is also composed of a plurality of striped patterns whose sides are away from the substrate and extend to the edge of the adjacent pixel area. The details of such strips will be described below. The method of forming the shape pattern.

[0082] Please refer to Figure 9A Firstly, a substrate 400 with a plurality of pixel regions 402 is provided, and a plurality of auxiliary patterns 904 are formed on the substrate 400 . Wherein, each auxiliary pattern 904 extends from the corresponding pixel area 402 to the periphery of the pixel area 402 . That is to say, the auxiliary pattern 904 covers the substrate 400 in the pixel area 402 , and its area is larger than that of the pixel area 402 .

[0090] Figure 12A to Figure 12D It is a cross-sectional view of the manufacturing process of the color filter substrate in the third embodiment of the present invention in sequence. Please refer to Figure 12A First, a plurality of color filter patterns 510 are formed on the substrate 500, and the formation method, material and arrangement of these color filter patterns 510 are, for example, the same as the color filter patterns 410 of the first and second embodiments, I won't repeat them here. In addition, in order to accurately form the color filter patterns 510 at predetermined positions on the substrate 500 , alignment marks (not shown) are usually made on the substrate 500 before forming the color filter patterns 510 . In this embodiment, for example, before forming the color filter pattern 510 , a laser chemical vapor deposition process is performed to form an alignment mark on the substrate 500 . After that, color filter patterns 510 are formed on the substrate 500 ...

Abstract

The present invention discloses A colour optical filtering substrate and manufacturing method, wherein said colour optical filtering substrate including substrate plurality of colour optical filtering pattern set on substrate, black matrices and sharing electrode. Colour optical filtering pattern is respectively set every pixel zone in substrate. Black matrices consist of plurality of strip patterns set among pixel zones for isolating these pixel zones. Each strip pattern side is far from substrate and extended to adjacent pixel zone edge, for avoiding display generating squint light leak phenomena. Sharing electrode is set above substrate for covering colour optical filtering pattern and black matrices.

Description

technical field [0001] The present invention relates to a color filter substrate and its manufacturing method, and in particular to a color filter substrate capable of providing good display contrast or viewing angle and its manufacturing method. Background technique [0002] The rapid progress of the multimedia society is largely due to the rapid progress of semiconductor components and display devices. As far as display devices are concerned, Liquid Crystal Displays (LCDs), which have superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation, have gradually become the mainstream of the market. [0003] figure 1 It is a partial cross-sectional schematic diagram of a display panel of a known liquid crystal display. Please refer to figure 1 The liquid crystal display panel 100 is mainly composed of an active element array substrate 110 , a color filter substrate 120 and a liquid crystal layer 130 dispose...
