Abstract

A display device according to the present disclosure includes a first electrode, an inorganic hole injecting and transporting layer which is formed of an inorganic material and is formed on the first electrode, at least two light emitting units including a first organic light emitting unit and a second organic light emitting unit having different luminescent colors which are formed on the inorganic hole injecting and transporting layer, an electron transport layer which is formed on the at least two organic light emitting units, and a second electrode which is formed on the electron transport layer. Furthermore, a light emitting layer of the first organic light emitting unit is formed by laminating a light emitting layer of a first luminescent color and a light emitting layer of a second luminescent color, and a light emitting layer of the second organic light emitting unit is formed of the light emitting layer of the second luminescent color.
