Color filter and method for manufacturing the same

Abstract

The method comprises: providing a baseboard; setting up a thin film transistor array on the baseboard; forming an insulating layer on the thin film transistor array; removing the insulation layer in order to reduce the thickness of the insulation layer located in the scan line area between the transistors; setting up a patterned light shading layer on the insulation layer; forming a color filtering layer on the insulation layer; the patterned light shading layer is around the color filter layer; forming a transparent conducting layer on the color filter layer.

Description

technical field [0001] The invention relates to a color filter, in particular to a color filter and a manufacturing method thereof. Background technique [0002] Due to the advantages of high image quality, small size, light weight, low voltage drive, low power consumption and wide application range, liquid crystal displays have been widely used in electronic product display devices, such as portable TVs, mobile phones, video recording Consumer electronics or computer products such as laptops, laptops, and desktop monitors have become the mainstream of displays. The production of general thin film transistor liquid crystal display can be roughly divided into thin film transistor array (TFT array) process, color filter (color filter) process, liquid crystal display unit assembly (liquid crystal cell assembly) process, and liquid crystal display module (liquid crystal module) Process. [0003] The thin film transistor array process is used to manufacture the thin film transi...

AI Technical Summary

Problems solved by technology

The use of inkjet technology on the array substrate still needs to consider the design of the retaining wall. Because the thickness of the color layer is about 1.4 microns or more, it cannot be manufactured using the film thickness of the components on the array substrate.

However, the height of the wall will affect the thickness of the color filter, and the surface strength between the ink and the wall will also increase the limitations of the material and process of the wall and ink when making the color filter.
