A conventional liquid crystal display comprises a number of components, so that a manufacturing cost cannot be reduced. Furthermore, a large-area substrate has problems in shipping. According to this invention, a liquid-crystal panel is prepared by forming individual optically functional films, a TFT device and a light-emitting device on a long thin film and then laminating the film by a transfer process. A base film to be a substrate in a liquid-crystal panel preferably has a thickness of 10 μm to 200 μm, a curvature radius of 40 mm or less as a measure of flexibility and a coefficient of thermal expansion of 50 ppm/° C. or less. Furthermore, it more preferably gives a variation of ±5% or less in mechanical and optical properties to a thermal history at 200° C.
