Abstract:
A liquid-crystal display device, comprising:a first substrate for receiving incident light, said first substrate having an inner surface on which a transparent electrode is formed; a guest-host liquid-crystal layer beneath the transparent electrode which contains a dichroic dye and which is uniformly oriented with respect to said transparent electrode; a plurality of reflective pixel electrodes beneath the liquid-crystal layer, each pixel electrode having formed thereabove in sequence a portion of an optical thin film layer followed by a portion of a passivation layer adjacent and beneath the liquid crystal layer; the optical thin film layer having a predetermined optical anisotropic axis formed from a liquid-crystal polymer having liquid crystal molecules uniaxially oriented along the optical anisotropic path such that the optical thin film layer functions as a &lgr;/4 phase shifter; a switching element associated with each of the pixel electrodes, said switching elements being formed beneath the respective pixel electrode; a lower substrate following beneath the switching element; and said optical thin-film layer including a plurality of coloring areas, and a pattern is formed for each coloring area, so as to form color filters.
