Patent ID: 8405100

Claim:
An organic electroluminescence display unit comprising: a lower electrode provided on a substrate for each of a blue first organic electroluminescence device and a second organic electroluminescence device of first color different from blue; a first hole injection/transport layer provided on the lower electrode for each of the first organic electroluminescence device and the second organic electroluminescence device, and having at least one of hole injection characteristics and hole transport characteristics; a second organic light emitting layer of the first color provided on the first hole injection/transport layer for the second organic electroluminescence device; a second hole injection/transport layer provided on the entire surfaces of the second organic light emitting layer and the first hole injection/transport layer for the first organic electroluminescence device, and being made of a low molecular material; a blue first organic light emitting layer provided on the entire surface of the second hole injection/transport layer; and an electron injection/transport layer having at least one of electron injection characteristics and electron transport characteristics, and an upper electrode that are provided in sequence on the entire surface of first organic light emitting layer.
