Abstract
A liquid crystal device is constituted by a pair of substrates, a liquid crystal disposed between the substrates, and an optical member having a planar extension in parallel with the substrates and a non-uniform optical anisotropy along the planar extension. As a result, it is possible to realize a liquid crystal device capable of irregularity-free optical modulation, particularly a liquid crystal display device capable of providing display images with improved contrast and viewing angle characteristic.
Claims20
A liquid crystal device, comprising a pair of substrates and a liquid crystal disposed between the substrates, said liquid crystal device further comprising an optical member having a planar extension parallel to the substrates;
- wherein said optical member has a distribution of optical anisotropy which varies from a center to a periphery in the planar extension, such that lines each joining points of equal optical anisotropy do not intersect each other in the planar extension.
A liquid crystal device of the active matrix type, comprising a pair of substrates and a liquid crystal disposed between the substrates so as to form a matrix of rectangular pixels;
- each pixel being provided with a source line disposed alone a side of the pixel;
- a gate line disposed along another side of the pixel and intersecting the source line, and a switching device disposed at an intersection of the source and gate lines close to a corner of the pixel;
- said liquid crystal device further comprising an optical member having a planar extension parallel to the substrates and divided into regions, each region corresponding to a pixel and having a sub-region of optical anisotropy covering a Portion of the pixel close to a switching device provided to the pixel.
