Abstract

The invention provides an optical compensative sheet for modifying display quality of a liquid crystal display device. An optical compensative sheet using a cellulose acylate, of which the in-plane retardation value (Re) is 0 nm ≤ Re < 20 nm, the thickness (d) is 10 μm < d < 85 μm, the average ((Vmin+Vmax)/2) of minimum value (Vmin) and maximum value (Vmax) of the sonic velocity measured in plane of film is 2.2 km/sec < (Vmin+Vmax)/2 < 2.5 km/sec, and the proportion (Vmin/Vmax) of minimum value of the sonic velocity measured in plane of film as compared to the maximum value is 1.01 < Vmin/Vmax/2 < 1.02. An optical compensative sheet made by laminating an aligned membrane and an optically anisotropic layer in this order onto a transparent support comprising at least a micro particle having an average primary particle diameter of less than 80 nm and thickness of more than 20 μm but less than 80 μm, wherein the arithmetic average roughness (Ra) of surface unevenness related to a surface at the aligned membrane side of transparent support is more than 0.0002 μm but less than 0.1 μm measured according to JIS B0601-1994, the ten-points average roughness (Rz) is more than 0.0002 μm but less than 0.3μm, as well as the maximum height (Ry) is more than 0.002 μm but less than 0.5 μm, Re value of transparent support is more than 2 nm but less than 200 nm and the Rth value is more than 50 nm but less than 400nm. An optical compensative sheet using a cellulose acylate film comprising a cellulose acylate film having an acylation index of 59.0 to 61.5%, of which the surface is treated by soapnification and contact angle with water of the surface is more than 30 DEG but less than 70 DEG.
