摘要： Disclosed is a vertically aligned liquid crystal display (VA-LCD) having wider viewing angle and having high contrast at the right angle and tilt angles. According to one embodiment of the present invention, the VA-LCD having liquid crystal cells in which liquid crystals with a negative dielectric anisotropy are filled and which is provided between a first polarizer and a second polarizer, whose absorption axises are perpendicular to each other, includes a sheet of +A plate and a sheet of -C plate, disposed between the first polarizer and the liquid crystal cells; and a sheet of +A plate disposed between the second polarizer and the liquid crystal cells, wherein an optical axis of the +A plate near the first polarizer is perpendicular to the absorption axis of the first polarizer, and an optical axis of the +A plate near the second polarizer is perpendicular to the absorption axis of the second polarizer. According to another embodiment of the present invention, a VA-LCD having liquid crystal cells in which liquid crystals with a negative dielectric anisotropy are filled and which are disposed between a first polarizer and a second polarizer, whose absorption axises are perpendicular to each other, includes a bi-axial retardation film disposed between the first polarizer and the liquid crystal cells, and a sheet of +A plate disposed between the second polarizer and the liquid crystal cells, wherein an optical axis of the bi-axial retardation film near the first polarizer is perpendicular to the absorption axis of the first polarizer, and an optical axis of the +A plate is parallel with the absorption axis of the second polarizer. Accordingly, the configuration of FlG. 11 has not an advantage more than the configurations of F1G.2 and 3 in aspects of manufacturing process and cost. The VA-LCD according to the present invention has an advantage that viewing angle compensation effect is enhanced due to the arrangement of the viewing angle compensation films, thereby implementing the wider viewing angle characteristic.

摘要： An IPS-LCD, in which the direction of an optical axis and retardation values are adjusted according to the disposition of a phase retardation film replacing one protective film, obtains a contrast ratio similar to that of an IPS-LCD having upper and lower protective films, and has a small thickness. The IPS-LCD includes first and second polarizing plates (1, 2), an IPS panel (3), and a first protective film. Absorption axes (4, 5) of the first and second polarizing plates (1, 2) are orthogonal to each other, and an optical axis of a liquid crystal in the IPS panel (3) and the absorption axis (4) are parallel with each other. A second phase retardation film, obtained by coating a biaxial film (17) with a uniaxial C film (11), is disposed between the second polarizing plate (2) and the IPS panel (3) and is used as a second protective film.

摘要： The present invention relates to a retardation film having a homeotropic alignment liquid crystal film, a polarizing film, an IPS (In-Plane Switching) mode liquid crystal display and a method for preparing the same. More particularly, the present invention relates to a homeotropic alignment liquid crystal film prepared from a liquid crystal mixed solution containing a poly-merizable reactive liquid crystal monomer so as to improve a viewing angle characteristic of an ISP mode liquid crystal display and reduce a color shift; a retardation film prepared by integrating an oriented retardation film and a method for preparing the same; a polarizing film having the retardation film located between a polarizing element or plate and a liquid crystal cell and a method for preparing the same; and an IPS mode liquid crystal display having the polarizing film. There is an advantage in that since a homeotropic alignment liquid crystal film with a retardation of a thickness direction is prepared using a liquid crystal mixed solution containing a reactive liquid crystal monomer, a retardation film according to the present invention is not required for high-temperature heat treatment and cooling processes so that it can be applied to a high-speed continuous process. Further, there is an advantage in that a retardation film having an oriented retardation film integrated with the homeotropic alignment liquid crystal film is arranged between a polarizing element or polarizing plate of an IPS mod liquid crystal display and a liquid crystal cell so that a contrast ratio can be increased up to about 1520%, and a color shift characteristic can be also improved.
摘要翻译：本发明涉及具有垂直取向液晶膜，偏振膜，IPS（平面切换）模式液晶显示器的相位差膜及其制备方法。更具体地说，本发明涉及由含有可聚合反应性液晶单体的液晶混合溶液制备的垂直取向液晶膜，以提高ISP模式液晶显示器的视角特性并减少色偏 ; 通过将定向延迟膜及其制备方法整合而制备的延迟膜; 具有位于偏振元件或板与液晶单元之间的延迟膜的偏振膜及其制备方法; 和具有偏振膜的IPS模式液晶显示器。具有以下优点：由于使用含有反应性液晶单体的液晶混合溶液来制备具有厚度方向延迟的垂面取向液晶膜，所以根据本发明的延迟膜不需要高温热处理和冷却过程，使其可以应用于高速连续过程。此外，具有将具有与垂直取向液晶膜成一体的定向延迟膜的相位差膜配置在IPS模式液晶显示器的偏振元件或偏振片与液晶单元之间，使得对比度可以增加至约1520％，并且还可以改善色移特性。
