Abstract
One embodiment of the present invention is an organic electroluminescence display, including: a substrate with a partition wall between adjacent organic electroluminescence elements; a first electrode layer formed on the substrate; a hole transport layer formed on both the first electrode layer and the partition wall; an underlayer formed on the hole transport layer; a first light emitting layer formed on the underlayer, emitted light from the first light emitting layer having a first wavelength; a second light emitting layer formed so as to partially overlap the first light emitting layer, emitted light from the second light emitting layer having a second wavelength, and the second wavelength being longer than the first wavelength; and a second electrode layer, wherein overlapping point of the first light emitting layer and the second light emitting layer is above the partition wall.
