Problems solved by technology

However, reducing the film thickness of the black matrix 120 will reduce the light-shielding efficiency of the black matrix 120 and cause light leakage, and reducing the overlap between the colored pattern 130 and the black matrix 120 will increase the color mixing phenomenon.
Therefore, neither of the above two methods is a good solution

Embodiment Construction

[0056] Fig. 2A is a partial schematic view of a color filter plate according to an embodiment of the present invention, and Fig. 2B is a schematic cross-sectional view along A-A' of Fig. 2A. Please refer to FIG. 2A and FIG. 2B , the color filter plate 200 of the present invention includes a substrate 210 , a black matrix 220 and a plurality of colored patterns 230 . The black matrix 220 is disposed on the substrate 210 and defines a plurality of sub-pixel regions 222 on the substrate 210 . When the color filter plate is paired with the array substrate (not shown in the figure), the sub-pixel regions 222 correspond one-to-one to the sub-pixel regions (not shown in the figure) of the array substrate. In addition, the black matrix 220 is mainly used for light shielding, and it can correspond to areas such as metal wires and thin film transistors of the array substrate, so as to block stray light from the above areas.

[0057]Following the above, in each sub-pixel region 222, the...

Abstract

A color filtering plate is prepared as setting black matrix on base plate and defining out multiple sub-pixel region on base plate, setting height of black matrix at each sub-pixel region to be lower gradually from periphery of sub-pixel region to internal of sub-pixel region and setting color dyed patterns separately in sub-pixel regions.

Description

technical field [0001] The present invention relates to a color filter and its manufacturing method, and in particular to a color filter with a better flat surface and its manufacturing method. Background technique [0002] With the advancement of modern video technology, liquid crystal display devices have been widely used in display screens of consumer electronic products such as mobile phones, notebook computers, personal computers, and personal digital assistants (PDAs). The liquid crystal panel of the liquid crystal display device is mainly composed of an array substrate, a liquid crystal layer and a color filter plate, wherein the array substrate is paired with the color filter plate, and the liquid crystal layer is located between them. The above-mentioned color filter plate is formed by, for example, firstly forming a black matrix (Black Matrix), then forming a colored pattern, and then forming film layers such as an electrode layer or a protective layer.
