ABSTRACT:
An electroluminescent device is provided. The device has a stacked structure in which an electric field enhancing layer is present between a dielectric layer, which contacts an inorganic light-emitting layer, and an electrode. In the device, electrons are additionally supplied by the electric field enhancing layer to increase electroluminescent efficiency, enabling the device to emit light having desired brightness, and lengthening the life span of the device.
