Patent ID: 7643115

Claim:
A liquid crystal display unit, comprising a first substrate with a thin-film transistor provided thereon, and a second substrate with a color filter formed thereon, said first substrate and said second substrate are attached together, and a liquid crystal is sealed in a gap between said first substrate and said second substrate, wherein there are provided: a first reflective electrode installed on inner surface of said first substrate and having reflective surfaces on front and rear surfaces, said first reflective electrode having a reflective lens structure with a convex portion to face toward said second substrate, and having an opening at the vertex of said convex portion; a second reflective film disposed between said first reflective electrode and said first substrate and under said opening of said first reflective electrode, said second reflective film having reflective surface on a front surface facing to said first reflective electrode; a light entering from said first substrate is reflected by the rear surface of said first reflective electrode and by the front surface of said second reflective film, said light is converged to said opening of said first reflective electrode and is allowed to pass toward said second substrate; and wherein said first reflective electrode of a reflective lens structure with a convex portion is over an organic PAS film prepared on said first substrate and is designed in such shape as to match surface roughness of said organic PAS film.
