<p>PURPOSE:To obtain a black matrix having high reliability without causing peeling of films in the succeeding processes by forming a base layer comprising a polyimide resin of specified or more thickness between a light-transmitting substrate and the black matrix. CONSTITUTION:This color filter has a laminated black matrix having a light- shielding agent dispersed in a polyimide resin formed on a light-transmitting substrate. In this color filter, a base layer comprising a polyimide resin of >=10nm thickness is formed between the light-transmitting substrate and the black matrix. As for the light-transmitting substrate, inorg. glass such as borosilicate glass and soda lime glass coated with silica, or an org. plastic film or sheet is preferably used. The base layer has high adhesion strength with the light-transmitting substrate and has an effect to prevent contamination of the black matrix with a minute amt. of alkali metals or alkaline earth metals on the light-transmitting substrate. Therefore, adhesion property between the base layer and the black matrix can be improved.</p> |
