ABSTRACT:
A microlens substrate for an opposed substrate for use in a liquid crystal panel is provided. The microlens substrate includes: a substrate with concave portions having a plurality of concave portions; a convex lens substrate having convex lenses, each of the convex lenses having a shape corresponding to each of the concave portions, and the convex lens substrate being provided with respect to the substrate with concave portions so that the convex lenses are opposed to the corresponding concave portions, respectively; and a coating layer provided on the surface of the convex lens substrate which does not face the substrate with concave portions, the coating layer being mainly constituted of a product material produced by a reaction of a polysilazane compound with water, wherein the polysilazane compound is represented by the following formula (I):A method of manufacturing the microlens substrate, a liquid crystal panel provided with the microlens substrate, and a projection type display apparatus provided with the liquid crystal panel are also provided.
