Problems solved by technology

In this method of opening, the size of the aperture is not easy to control, which greatly increases the difficulty of production; on the other hand, the difficulty of controlling the size of the aperture leads to the uncertainty of the aperture area, resulting in deviations between the obtained color and the design value

Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] An embodiment of the present invention provides a method for manufacturing a color filter. A porous template such as aluminum oxide is used to form uniformly distributed transparent columns in the pixel area on the substrate. hole. In addition, by adjusting the size and pore density of the porous template, accurate control of the pore diameter and pore area of ​​the holes opened in the pixel area can be realized. At the same time, the transparent columns function as columnar spacers. Because they are evenly distributed in the pixel area, the stability of the cell thickness is improved, and poor display caused by uneven cell thickness can be avoided.

Abstract

A method for manufacturing a color filter, the color filter, and a display device. The method for manufacturing the color filter includes: forming multiple transparent columnar objects in a pixel area of a substrate; forming on the substrate having formed thereon the transparent columnar object a black array that encircles to form the pixel area; and forming pixel resin layers in the pixel area, where the transparent columnar objects protrude outwards from the pixel resin layers to serve as columnar spacers. This allows for accurate control of the aperture size and aperture area of pores in the pixel area of the color filter.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a method for manufacturing a color filter, the color filter and a display device. Background technique [0002] In order to achieve higher transmittance and brightness of the color filter, the way of opening holes in the pixel area of ​​the color filter is often used in the prior art. The application is particularly extensive. In order to obtain high-quality color images in both bright and dark environments, the semi-reflective and semi-transparent color filters should take into account both their reflection performance and transmission performance. Both performances require the color filter to have as high a brightness and color as possible. saturation. For this reason, in the prior art, holes are generally opened in the reflective area to achieve a balance between brightness and color saturation. [0003] In the prior art, the realization of the color opening technology...
