Abstract
Disclosed is a high quality display device which avoids complicated element structure, and does not unnecessarily reduce portability. The display device comprises: a pair of substrates which are disposed facing each other, and on each of which electrodes are formed; and a material layer which is sandwiched between the pair of substrates. The material layer contains: a coloring material which changes color upon the application of a voltage; and a light-emitting material which emits light upon photoexcitation.
