  • Method of manufacturing array substrate for display device and method of manufacturing display device
    Publication number: 20010029055
    Abstract: In the manufacturing method of an array substrate for a planar display device, a first pattern is formed on a substrate by correcting in advance the size of the first pattern in view of an amount of deformation of the substrate. Then, the next pattern is formed on the substrate in conformity with the pattern formed in the preceding step.

  • Electrooptical liquid crystal device
    Patent number: 5825445
    Abstract: In an electooptical liquid crystal device comprising an OCB mode liquid crystal cell and an optically anisotropic element compensating a viewing angle characteristics of the cell, the optically anisotropic element satisfies the elliptical coefficient Z of the index ellipsoid of the optically anisotropic element,7.ltoreq.Z.ltoreq.10,if Z=(ndx-ndz)/(ndx-ndy),where ndx, ndy and ndz represent the components in x, y and z directions of the products of the refractive indice n of optically anisotropic element and the thickness of the optically anisotropic element, when the optically anisotropic element is combined with the bend-aligned liquid crystal cell as the electrooptical liquid crystal device.
