Abstract:
An organic EL display device includes a blue pixel, and a second pixel configured to output light having a peak wavelength longer than that of blue light. The blue pixel includes a blue phosphorescent luminescent material containing layer and a blue fluorescent luminescent material containing layer as common layers common to the plurality of pixels, and the second pixel includes a second phosphorescent luminescent material containing layer provided in each of the second pixel, adjacently to the common layers at the side of an anode from the common layers.
