Abstract
The present invention is a method of manufacturing a liquid crystal display device, wherein light having an exposure energy is irradiated on the surface of a photo-sensitive resin layer having a predetermined film thickness, and a distribution of thermal deformation characteristics in the thickness direction (or the plane direction) of the photo-sensitive resin layer is formed, then heat treatment is performed to form random undulation (micro-grooves or micro-wrinkles) on the surface of the photo-sensitive resin layer.
Claims14
A method of manufacturing a substrate for a liquid-crystal display device comprising the steps of:
- forming a resin layer on a substrate;
- selectively reforming the surface portion of said resin layer by applying energy with an energy density per unit time of a prescribed value or more to said resin layer to generate a difference in a rate of thermal shrinkage between said surface portion and the layer portion other than the surface portion in said resin layer;
- performing a heat treatment to said resin layer to form random wrinkles of micro-grooves in said surface portion, said random wrinkles of micro-grooves having ridges of a linear or curved continuous pattern;
- and
- forming reflective electrodes on said surface portion.
A method of manufacturing a substrate for a liquid-crystal display device comprising the steps of:
- forming a resin layer on a substrate;
- selectively reforming the surface portion of said resin layer by applying energy with an energy density per unit time of a prescribed value or more to said resin layer without using a mask to generate a difference in a rate of thermal shrinkage between said surface portion and the layer portion other than the surface portion in said resin layer;
- performing a heat treatment to said resin layer to form random wrinkles of micro-grooves in said surface portion;
- and
- forming reflective electrodes on said surface portion.
