Patent ID: 7973893

Claim:
A method of manufacturing a substrate for a liquid-crystal display device comprising the steps of: coating a resin layer on a substrate, wherein a condition of the resin layer can be any one of at least three conditions including a non-hardened condition, a semi-hardened condition and a hardened condition through a heat treatment; performing a first heat treatment to the resin layer to make the resin layer into the hardened condition or the semi-hardened condition; applying energy having an energy density per unit time, which is more than a prescribed value, to the resin layer so as to selectively reform the surface portion of said resin layer and to generate a difference in a rate of thermal shrinkage between said surface portion and the layer portion other than the surface portion; performing a second heat treatment to the resin layer to form wrinkles of micro-grooves in said surface portion due to the difference in the rate of thermal shrinkage generated by the application of energy; and forming a reflective electrode on said surface portion.
