<p>PURPOSE:To improve the contrast of a liquid crystal panel, and to improve the contrast of a liquid crystal panel, by constituting the titled display so that a liquid crystal molecule becomes roughly a vertical orientation or a hybrid orientation against a substrate, when no voltage is applied, and the liquid crystal goes to roughly horizontal against the substrate and a 90 deg. twist structure, at the time of application of a voltage. CONSTITUTION:Upper and lower polarizing plates 11, 12 are installed so as to cross vertically polarizing axes 56, 57. Oriented films on glass substrates 13, 14 are formed by superposing vertical oriented films 16, 17 on horizontal oriented films 15, 18 (an oblique vapor-deposited film of an inorganic matter or an organic film for rubbing). Also, oriented films on the glass substrates 13, 14 have a structure which has super posed horizontal oriented films 15, 18 on vertical oriented films 16, 17. In such cases, a liquid crystal 19 whose dielectric anisotropy iis negative forms a vertical orientation, at the time of no voltage is applied, and becomes a horizontal twist arrangement, at the time of a voltage is applied. Also, in case one of the glass plates is the horizon tal oriented film 15 and the other substrate is a laminated structure of the horizontal oriented film 17 and the vertical oriented film 18, it is also allowed that the horizontal oriented film 17 and the vertical oriented film 18 are laminated in reverse in its upper and lower parts.</p> |
