| abstract |
Disclosed is a rectangular optical compensatory sheet having a shorter side of not less than 14 cm which comprises a transparent support, an orientation layer provided thereon and an optically anisotropic layer provided on the orientation layer, the optically anisotropic layer comprising a compound having one or more discotic structure units in its molecule, and whose variation of retardation in overall area is within X+/-5 nm wherein X is in the range of 0 to 100 nm, the retardation being represented by the formula: (nx-ny)xd in which nx and ny are main refractive indices on the plane of the sheet and d is the thickness of the sheet in terms of nm. Further, a liquid crystal display and a color liquid crystal display provided with the optical compensatory sheet are disclosed. |
