LIGHT EMITTING DEVICE AND INDICATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a new light emitting device utilizing amorphous oxide. …Ž

SOLUTION: The device comprises a light emitting layer intervening between a first and a second electrodes, and a field effect transistor. The active layer of the field effect transistor is an amorphous oxide which is less than 10<18>/cm<3> in electronic carrier density, or an amorphous oxide having a tendency in which the electronic carrier density increases and electron mobility increases simultaneously, or a transparent amorphous oxide semiconductor enabling normally-off. …Ž
