Abstract
Organic electroluminescence (EL) devices displaying the information of a camera are formed directly on a surface of a screen mat arranged near an image formation surface of a finder optical system. A CPU for the camera drives the organic EL device, under a forward or a reverse bias, as required, to enable light of a green or a red color to be emitted.
