Abstract
A display device includes: a substrate; a switching element on the substrate; an insulating layer on the switching element; a pixel defining film on the insulating layer and including an opening overlapping a part of the insulating layer; a lower electrode on a side surface of the pixel defining film defining the opening and electrically connected with the switching element; a reflective pattern on the insulating layer exposed through the opening and spaced apart from the lower electrode; a light emitting layer on the lower electrode and the reflective pattern; an upper electrode on the light emitting layer; and a wavelength conversion layer on the upper electrode and arranged in the opening.
