FIELD: electricity.
SUBSTANCE: in accordance with the invention concept the proposed light-emitting device contains a light-emitting element with the first and the second electrodes and a light-emitting layer positioned between the first and the second electrodes, a field transistor for the light-emitting element excitation whose effective layer is composed of an amorphous oxide with an electronic media concentration less than 1018/cm3. Additionally proposed are two versions of the light-emitting device design, an electrophotographic device, an active matrix display device and a product for display.
EFFECT: development of devices whose electrophysical properties ensure high contrast with display devices as may be equipped with the light-emitting device under consideration in accordance with the invention concept.
