Abstract
In a liquid crystal display device having a reflection electrode of a reflection diffuser panel shape formed with surface roughness, a liquid crystal orientation film for realizing a predetermined pre-tilt angle is formed on the reflection electrode by an optical orientation, technique. A liquid crystal display device having a reflection electrode of a reflection diffuser panel shape formed with surface roughness provided on a driving substrate and an ultraviolet-reactive liquid crystal orientation film formed on the reflection electrode is produced by first step of forming a protective film made of a material transparent to a visible light for absorbing an ultraviolet light on the reflection electrode on the driving substrate side so as to eliminate the level difference in the surface roughness of the reflection electrode; a second step of coating a composition for an ultraviolet-reactive liquid crystal orientation film onto the protective film; and a third step of forming a liquid crystal orientation film on the coating film of the composition for a liquid crystal orientation film by irradiating a polarizing ultraviolet light L onto the substrate surface in the slanting direction.
