摘要： A liquid crystal display device comprises a pair of substrates (11, 12) bonded to each other by a sealing material (13) in the form of a frame provided therebetween, liquid crystal (14) held between the pair of substrates; a reflective layer (111) formed on one (11) of the substrates, and an alignment film (116) formed over the reflective layer (111) at the liquid crystal side. The surface of said one (11) of the substrates has a roughened area (11b) which is roughened and a flat area (11a) which is flat and surrounds the roughened area (11b). The alignment film (116) is formed in the roughened area (11b), and the sealing material (13) is formed in the flat area (11a).

摘要： The liquid crystal device of the present invention effectively prevents reversion of bright/dark states between a reflective display mode and a transmissive display mode. The liquid crystal device includes a first absorptive polarizer, which receives light from outside; a liquid crystal cell, which receives light emitted from the first absorptive polarizer; a second absorptive polarizer, which receives light emitted from the liquid crystal cell; and a reflective polarizer, which receives light emitted from the second absorptive polarizer. The reflective polarizer has an axis of reflection in a predetermined direction to reflect at least part of light that has been transmitted through the first absorptive polarizer, the liquid crystal cell, and the second absorptive polarizer to be incident on the reflective polarizer. The reflective polarizer partially transmits light including a linearly polarized light component which is included in light entering the reflective polarizer from an opposite side to the second absorptive polarizer and which is to be transmitted through the second absorptive polarizer. The first absorptive polarizer has an axis of transmission in a specific direction to cause light, which has been reflected by the reflective polarizer and transmitted through the second absorptive polarizer, to be transmitted through the first absorptive polarizer.
