Abstract: A camera module includes an image sensor IC, a resin multilayer board including thermoplastic resin layers stacked in a direction perpendicular or substantially perpendicular to a light receiving surface of the image sensor IC, a mounting electrode which is stacked on the thermoplastic resin layer and on which the image sensor IC is mounted, and a via-hole conductor electrically connected to the mounting electrode. The resin multilayer board includes a flat plate portion including a surface on which the mounting electrode is mounted, and a rigid portion including a greater number of thermoplastic resin layers than that of the flat plate portion, and the via-hole conductor is arranged in the flat plate portion so as to avoid the thermoplastic resin layer on which the mounting electrode is stacked.

Abstract: 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 ?m to 200 ?m, 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.
