Organic electroluminescent display device and method of producing the same
Abstract:
An organic electroluminescent display device in which a plurality of light-emitting cells each having an organic electroluminescent portion are arranged on a substrate, wherein, for each of the light-emitting cells, a first transistor which controls energization on the organic electroluminescent portion, and a second transistor which switches a signal to be given to an input of the first transistor are disposed, active layers of the first and second transistors are formed by an amorphous oxide semiconductor, and, the first and second transistors are formed so that, when the first and second transistors are driven under same conditions, an amount of an output current of the first transistor is smaller than an amount of an output current of the second transistor.
