ABSTRACT:
A display device includes a non-luminescent type display element (an electro-chromic display element) which changes concentration with a voltage applied thereto, and a self-luminescent type display element (an electro-luminescent display element) which emits light according as a voltage is applied thereto. The two display elements are laminated together and formed, one as a color forming layer and the other as a luminescent layer, into a desired shape for visual observation. The laminated display elements are arranged in a visually observable display part of the display device.
