摘要

There is provided a method for forming a concave-convex pattern, comprising: the first step of forming a photosensitive resin layer comprising an alkali-insoluble resin and a negative-working photosensitive resin on a substrate; the second step of exposing the photosensitive resin layer through a photomask having a desired opening pattern; and the third step of developing the exposed photosensitive resin layer with an alkaline developing solution followed by curing treatment to form a concave-convex pattern consisting of convexes corresponding to the regions exposed in accordance with said opening pattern and concaves corresponding to the non-exposed regions. There is also provided a method for forming a concave-convex pattern, comprising: the first step of forming a photosensitive resin layer comprising a thermosetting resin and a negative-working photosensitive resin on a substrate and then heat treating the photosensitive resin layer in such a manner that at least a part of the thermosetting resin is cured; the second step of exposing the photosensitive resin layer through a photomask having a desired opening pattern; and the third step of developing and curing the photosensitive resin layer to form a concave-convex pattern consisting of convexes corresponding to the regions exposed in accordance with said opening pattern and concaves corresponding to the non-exposed regions. There is further provided a color filter for liquid crystal displays, comprising: a substrate; a colored layer of a plurality of predetermined color patterns on the substrate; a transparent protective layer provided so as to cover at least the colored layer; and transparent columnar convexes which are provided on the substrate in its plurality of predetermined portions and are protruded from the transparent protective layer, the transparent protective layer and the columnar convexes having been formed by any one of the above methods.
