Method of forming concave-convex pattern and use of the method in the production of color filters for liquid crystal displays

摘要

A method of forming raised and recessed patterns comprising: the first step of forming over a substrate a photosensitive resin layer including an alkali-insoluble resin and a negative type photosensitive resin, or the first step of forming over a substrate a photosensitive resin layer including a thermosetting resin and a negative type photosensitive resin and then heat-treating the photosensitive resin layer to harden at least a part of the thermosetting resin; the second step of exposing the photosensitive resin layer; and the third step of developing the photosensitive resin layer and hardening it to form a raised and recessed pattern including raised portions representing an exposed region and recessed portions representing an unexposed region. Liquid crystal display color filters which comprises over the substrate a colored layer, and a transparent protective layer and transparent columnar raised portions formed by one of the above two methods.
