摘要： A display device includes a substrate, regions on the substrate each including a transparent first and a second regions, one or more light-emitting elements disposed in the second region, and a circular polarizing pattern disposed in front of the pixel regions. Each of the one or more light-emitting elements includes a reflective electrode and a transparent electrode layered one above the other, and a light-emitting film provided between the transparent electrode and the reflective electrode. The light-emitting film is configured to emit light in response to electric current supplied between the reflective electrode and the transparent electrode. The circular polarizing pattern covers the entire reflective electrode when seen from the front of the display device. At least a part of the first region is located within a gap in the circular polarizing pattern when seen from the front of the display device.

摘要： Each of subpixels includes: an upper electrode; a lower electrode; an organic light-emitting layer sandwiched between the upper electrode and the lower electrode; and a lower carrier supply layer sandwiched between the lower electrode and the organic light-emitting layer. The lower carrier supply layer is configured to: make contact with the lower electrode and the organic light-emitting layer, respectively; supply carriers from the lower electrode to the organic light-emitting layer; cover the lower electrode entirely in an opening of the pixel defining layer; and have an edge at a top surface of the pixel defining layer surrounding the lower electrode. The organic light-emitting layer covers an entire surface of the lower carrier supply layer including the edge of the lower carrier supply layer.
