Abstract
Abstract A light-source-incorporated image sensor in which a light receiving element formed on an insulating substrate is confronted through a light transmission layer with an EL light emitting element formed on a transparent substrate. In the image sensor, the thickness of the transparent substrate is smaller than that of the light transmission layer, whereby the focal depth can be set to a value which is sufficient in practical use.
