More Information
Summary:Provided is a display device including an organic insulating layer; a pixel electrode on the organic insulating layer; a pixel defining layer configured to cover an edge of the pixel electrode, having an opening corresponding to the pixel electrode, the pixel defining layer including a first layer including an inorganic insulating material and a second layer having less light transmittance in a first wavelength band than the first layer; an intermediate layer on a portion of the pixel electrode exposed via the opening, and including an emission layer; and an opposite electrode on the intermediate layer.
