Abstract: A reflective liquid crystal display device having high reliability and excellent display is provided by preventing degradation and peeling of an organic film provided in order to impart an uneven shape to a reflective metal film. The reflective liquid crystal display has a configuration in which a liquid crystal layer is held in the space formed by a pair of substrates arranged opposing to each other and a seal member provided on the periphery portion of the substrate pair, an organic film, a reflective metal film, color filters, an overcoat film, an electrode substrate film, electrode layers, and an orientation film are laminated in order on the liquid crystal layer side of one substrate of the substrate pair, and the organic film is formed in the neighborhood region of the end of the seal member provided on the periphery portion of the aforementioned substrate.

Abstract: A reflective bistable nematic liquid crystal display device includes a liquid crystal cell and a reflector provided on a side of the liquid crystal cell opposite to an observer side, with a transmissive adhesive layer interposed therebetween. The liquid crystal cell includes a pair of substrates opposite to each other, with a nematic liquid crystal layer in which a chiral agent is added therebetween, in which one of the pair of substrates has an alignment film with strong anchoring energy and the other has an alignment film with weak anchoring energy. The alignment film having the weak anchoring energy has anchoring energy smaller than half of that of the alignment film having strong anchoring energy and has a pre-tilt angle of about 0°.

Abstract: A liquid crystal color display device comprises a liquid crystal cell 3 having a liquid crystal layer with an angle of twist being within a range of 180.degree. to 270.degree. and a pair of electrode substrates intervening the liquid crystal layer therebetween, a twist phase plate 4 serving as a birefringent layer, and a pair of polarizers 2,5. The value of .DELTA.n.cndot.d of the phase plate 4, wherein .DELTA.n represents a refractive index anisotropy and d represents a thickness, and that of the liquid crystal layer in voltage-free condition are substantially at the same level within a range of 1.4 to 2.0 .mu.m. The value of .DELTA.n.cndot.d of the liquid crystal layer can be continuously changed by appropriately controlling a voltage applied thereto. By this, colorization of the device is possible.
