Zusammenfassung:	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.
