Abstract
An electrode substrate for a reflection type liquid crystal display device, which includes a substrate, and a light scattering film formed on the substrate and including a transparent matrix resin and scattering particles made of a resin. The light scattering film is formed from a coating liquid containing the transparent matrix resin and a resin for forming the scattering particles, which has a different refractive index from that of the matrix resin, both mixed in a solvent. The scattering particles are dispersed in the transparent matrix resin as a result of a phase separation due to the low compatibility between these resins as the solvent is evaporated from the coating liquid. The size and dispersed state of the scattering particles are at least two-dimensionally randomized as viewed from the front of the light scattering film.
