Description

Photosensitive resin composition and formed colored filter thereof and comprise the LCD assembly of this colored filter

Technical field

The photosensitive resin composition for colour filter of the relevant a kind of LCD of the present invention, has the LCD assembly that this constituent forms the colored filter of picture element layer and comprises this colored filter.Particularly provide a kind of pigment agglutination phenomenon to reduce, the development property when developing is good and the formed pattern in back that develops does not have the green picture element photosensitive resin composition of the colored filter of undercutting.

< > Background technology <>

At present, colored filter has been widely used in applications such as colour liquid crystal display device, colour facsimile apparatus, colour camera.Along with the market demand of imaging equipments such as colour liquid crystal display device day by day enlarges, also trend variation on the manufacturing technology of colored filter.

Usually, colored filter can by decoration method, print process, electricity methods such as method, pigment dispersing method, picture elements such as red, green, blue be formed on the transparent glass substrate make.Generally speaking, for improving the contrast of colored filter, can between the picture element dyed layer, dispose light shield layer (or claiming black matrix") again.

The processing procedure of above-mentioned pigment dispersing method system earlier with pigment dispersing in ray hardening resin and form colored photosensitive polymer combination, at last this resin combination is formed the picture element dyed layer.Furthermore; The processing procedure of pigment dispersing method; Usually system is earlier on transparent supports such as glass substrate; With metal or photoresist photomask formation light shield layer (back matrix) such as chromium, chromium oxide; And then will disperse the photoresist (chromatic photoresist agent) of red pigment this photoresist to be coated on the transparent support by the rotary coating mode; Make public by light shield, carry out after the exposure development treatment get final product red picture element; With same mode of operation, promptly repeat on support, to make three look picture elements such as red, green, blue respectively again by the mode of coating, exposure, development.

In recent years; The purposes of colour liquid crystal display device no longer is confined on the personal computer; Also be widely used in (especially large-sized color liquid crystal screen) on color TV and the various supervision screen, and in this application, generally all be attended by the requirement of high brightness, high-contrast.

The green picture element photosensitive resin composition of general colored filter is to adopt the halogenated phthalocyanines compound of central metal cupric as the painted pigment of using, and so its formed painted picture element but can't reach the requirement of high-contrast, high brightness.Therefore, such as openly specially permit for TOHKEMY 2003-161828 number communique announcement, change to adopt central metal to contain the halogenated phthalocyanines compound of zinc substituted.

Yet; The halogenated phthalocyanines compound that contains zinc with central metal is as coloring pigment; In its prepared photosensitive resin composition; When using general known light initiator; Openly specially permit the acetophenone (acetophenone that communique discloses as TOHKEMY 2009-222752 number) be light initiator or the benzophenone (benzophenone that openly speciallys permit the communique announcement for TOHKEMY 2009-198751 number) be the light initiator; Then all there is the pigment agglutination phenomenon of photosensitive resin composition to increase, problems such as the not good and formed pattern generation undercutting in back of developing of the development property during development.

Summary of the invention

Fundamental purpose of the present invention is to provide a kind of photosensitive resin composition for colour filter of LCD.Particularly provide a kind of pigment agglutination phenomenon to reduce, the development property when developing is good and the formed pattern in back that develops does not have the green picture element photosensitive resin composition of the colored filter of undercutting.
