Abstract
There is provided a display device (100) including a step forming member (14) which forms a step between a first region (s1) and a second region (s2) over a substrate (11) so that the first region (s1, 173R) becomes higher than the second region (s2, 173G) when viewed from the substrate (11), a first light emitting (173R) layer transferred to the first region, and a second light emitting layer (173G) transferred to the first region and the second region, and which has an emission wavelength shorter than an emission wavelength of the first light emitting layer.
