Abstract
Provided is a display device that even in the case where microlenses are formed to increase the light extraction efficiency, can decrease damage on an OLED caused by the production of the microlenses. The display device includes a first substrate; light emitting elements provided on the first substrate and located in correspondence with pixels arrayed in a matrix; a second substrate; a light collection layer provided on the second substrate and including, on the side facing the light emitting elements, at least one convex lens in correspondence with each of the pixels; and a light-transmissive layer that is provided between the first substrate and the second substrate so as to be in contact with the lens and has a refractive index lower than that of the light collection layer.
