1. A liquid crystal display unit, comprising one substrate with a thin-film transistor provided thereon, and the other substrate with a color filter formed thereon, said one substrate and the other substrate are attached together, and a liquid crystal is sealed in a gap between the two substrates, wherein there are provided:

  • a first reflective electrode installed on inner surface of said one 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 counter substrate, and having an opening at the vertex of said convex portion;

    a second reflective film disposed between said first reflective electrode and said one substrate and under said opening of said first reflective electrode, said second reflective film having reflective surface on the surface facing to said first reflective electrode; and

    a light entering from said one 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 the other substrate.
