Coloured liquid crystal display device

Abstract

A color LCD is composed of an array circuit substrate with a scan line and a data line to form multiple pixels, a film transistor formed on a pixel, a pixel electrode for connecting said film transistor, a black matrix layer on said array circuit substrate, a frame layer surrounding said black matrix layer, and a color filter layer on said array circuit substrate and black matrix layer and extended to cover on frame layer.

Description

technical field [0001] The invention relates to a color liquid crystal display device and a method for manufacturing a color filter layer and a black matrix on an array substrate. Background technique [0002] A typical liquid crystal display device includes an upper substrate and a lower substrate, and a liquid crystal layer is sandwiched between the two substrates. The upper substrate has a color filter layer and a common electrode, and the lower substrate has a switch element and a pixel electrode. The lower substrate is called an array circuit substrate. The upper and lower bases are made separately and then connected together. During the formation of the upper substrate, there will be some heating processes, such as: pre-baking, exposure, post-exposure baking, etc., which may cause deformation of the upper substrate component, resulting in misalignment of the upper and lower substrates during connection. Therefore, if the color filter layer and the light-shielding lay...

AI Technical Summary

Problems solved by technology

If any thickness of the color filter layer 400 or the frame layer 300 needs to be changed due to the manufacturing process or product requirements, the size of the spacer 1001 for the sealant will also be changed accordingly, thus increasing the complexity of the manufacturing process
