A process for making color filter

Abstract

The invention discloses a color optical filter making method, depending on the method to form photoresist or insulating space substance in non-pixel region, and avoiding the color relative permeation and mix phenomenon of other adjacent colorizing materials, so as to make the color optical filter with good color reappearance and color resolution. It includes: forming an interbedded insulating layer on a basal plate; forming many scanning lines and many signal lines on the interbedded insulating layer to define many pixel regions and a non-pixel region; forming a photoresist or insulating layer on the interbedded insulating layer; composing a picture of the photoresist or insulating layer to form photoresist or insulating space substance in the non-pixel region; and using spray-ink method to project a colorizing material in many pixel regions.

Description

Technical field

[0001] The present invention relates to a method for manufacturing a color filter, in particular to a method for manufacturing a color filter by an inkjet method. Background technique

[0002] Generally speaking, the main components of a liquid crystal display device are composed of two electrode substrates each having pixels (pixels) formed by electrodes that are arranged opposite to each other. They are arranged opposite each other with a gap, and an edge is sealed around the gap to sandwich the liquid crystal layer. constitute.

[0003] In liquid crystal display devices, particularly liquid crystal display devices that can display arbitrary color images, color filters are generally used. The color filter is provided with three primary colors of R, G, and B (red, green, and blue) on any one of the two electrode substrates, or an arrangement of colorable multi-color hue dyeing elements corresponding to each pixel.
