| 20090219467 | LIQUID CRYSTAL DISPLAY - A liquid crystal display comprises: first and second panels facing each other; a compensation film and a first polarizer disposed on the first panel, the compensation film having phase retardation characteristics; and a second polarizer having a supporting film disposed on the second panel, the supporting film having phase retardation characteristics. In alternative embodiments, a supporting film is used in place of the compensation film. The supporting film has retardation characteristics. | 09-03-2009 |
| 20100315582 | LIQUID CRYSTAL DISPLAY - 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 applied 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. | 12-16-2010 |

| 20090195744 | PATTERNED VERTICALLY ALIGNED LIQUID CRYSTAL DISPLAY - A liquid crystal display includes a gate line formed on a lower substrate, a storage line formed on the lower substrate, and a data line formed on the lower substrate crossing and insulated from the gate line and the storage line. The liquid crystal display also includes a pixel electrode formed on the lower substrate crossing and insulated from the storage line. The pixel electrode has a first aperture pattern. The liquid crystal display further includes a common electrode formed on an upper substrate and having a second aperture pattern, and a storage electrode connected to the storage line. The storage electrode overlaps the second aperture pattern. The storage line, first aperture pattern, and second aperture pattern each includes a straight portion slanting to the gate line.

| 20100296043 | LIQUID CRYSTAL DISPLAYS - A liquid crystal display comprises two parallel spaced substrates and a liquid crystal layer with negative dielectric anisotropy interposed between the substrates. The ratio d/p, the cell gap d between the substrates to the pitch p of the liquid crystal layer, is equal to or less than 0.3, and the retardation value Δn*d may be in the range of 0.25-0.4. In absence of electric field, the liquid crystal molecules are arranged vertically to the substrates, and when the sufficient electric field is applied, the liquid crystal molecules are parallel to the substrates and twisted by 90° from one substrate to the other. | 11-25-2010 |

| 20080273154 | LIQUID CRYSTAL DISPLAY HAVING WIDE VIEWING ANGLE - A tetragonal ring shape aperture is formed in the common electrode on one substrate and a cross shape aperture is formed at the position corresponding to the center of the tetragonal ring shape aperture in the pixel electrode on the other substrate. A liquid crystal layer between two electrodes are divided to four domains where the directors of the liquid crystal layer have different angles when a voltage is applied to the electrodes. The directors in adjacent domains make a right angle. The tetragonal ring shape aperture is broken at midpoint of each side of the tetragon, and the width of the aperture decreases as goes from the bent point to the edge. Wide viewing angle is obtained by four domains where the directors of the liquid crystal layer indicate different directions, disclination is removed and luminance increases. | 11-06-2008 |
