Abstract
The method of cleaning a coated sheet according to the present invention is characterized in that dry wind is brown along the traveling direction of a film onto the surface of a coating layer wherein the solid content and the viscosity of the coating solution are within specified ranges. By this method, the thickness precision of the coating film can be improved in its large area, and the evenness of its in-plane optically functional property can be made even therein. The speed of the dry wind, the temperature of the wind, and the thickness of the dried coating film are preferably within specified ranges. In particular, the coated sheet is very useful as an optical material having good properties in an optically functional layer which is frequently used as a large-area coated sheet, an optical device having such an optically functional layer, an optically compensating layer, or an optically compensating plate. The coated sheet is particularly effective for an image display on which they are mounted.
