摘要： Two electrodes in parallel with each other are formed on one of two substrates, homeotropic alignment films are formed on the substrates and a liquid crystal material having positive dielectric anisotropy is injected between the substrates. When the voltage is applied to the two electrodes, a parabolic electric field between the electrodes drives the liquid crystal molecules. Since the electric field generated is symmetrical with respect to the boundary-plane equal distance from each of the two electrodes, the liquid crystal molecules are symmetrically aligned with respect to the boundary-plane. The electric field does not exert influences the liquid crystal molecules on the boundary-plane since the electric field on the boundary-plane is parallel with the substrates and perpendicular to the two electrodes; and thus, it is perpendicular to the liquid crystal molecules. Here, the polarization of the light is changed while passing through the liquid crystal layer and as a result, only a part of the light passes through the polarizing plate. The transmittance of the light can be varied by controlling the magnitude of voltage applied to the two electrodes.

摘要： Two electrodes parallel to each other are formed on one of two substrates, homeotropic alignment films are formed on the substrates and a liquid crystal material having positive dielectric anisotropy is injected between the substrates. When a voltage is appled to the two electrodes, a parabolic electric field between the electrodes drives the liquid crystal molecules. Since the generated electric field is symmetrical with respect to the boundary-plane equal distance from each of the two electrodes, the liquid crystal molecules are symmetrically aligned with respect to the boundary-plane, and the optical characteristic is compensated in both regions divided by the boundary-plane, thereby obtaining a wide viewing angle. The electric field does not exert influences on the liquid crystal molecules on the boundary-plane since the electric field on the boundary-plane is parallel to the substrates and perpendicular to the two electrodes and thus, it is perpendicular to the liquid crystal molecules. Here, the polarization of the light is changed while passing through the liquid crystal layer and as a result, only a part of the light passes through the polarizing plate The transmittance of the light can be varied by controlling the magnitude of voltage applied to the two electrodes. The alignment direction of the liquid crystal molecules is changed in both regions of a bent portion of the electrodes by forming the electrodes in the saw shape in a pixel or in by pixel, and the retardation of the light is compensated, thereby obtaining a wider viewing angle.

摘要： A liquid crystal display includes a first substrate having a plurality of pixels, a second substrate facing the first substrate, polarizing plates attached to outer surfaces of the two substrates, and a liquid crystal material injected into the gap between the two substrates, molecules of the liquid crystal material being initially aligned perpendicularly to the substrates. Each pixel is divided into a plurality of domains distinguished by an average alignment direction of liquid crystal molecules included therein when an electric field is applied to the liquid crystal material. On average, liquid crystal molecules located at an edge of the domains are aligned symmetrically to each other with respect to a boundary of the domains. Polarizing directions of the polarizing plates are either perpendicular or parallel to each other, but neither parallel nor perpendicular to at least one of the average alignment directions of the liquid crystal molecules of the domains.

The upper and the lower polarizers having the perpendicular polarizing directions are provided on the outer surfaces of the upper and the lower panels, respectively. The voltage value of a first gray representing the darkest state applied between the pixel electrode and the common electrode is within a voltage range giving a contrast ratio to be equal to or higher than 0.8 with respect to contrast ratio when the voltage applied between the pixel electrode and the common electrode is zero. In this way, the contrast ratio and the color reproduction is improved, so that the image quality of a liquid crystal display is improved.
