Abstract
An organic EL display panel offering improved luminance includes: a substrate; pixel electrodes arranged in rows and columns; an insulating film coating the confronting edges of pixel electrodes adjacent in a column direction; banks each elongated in the column direction over a gap between pixel electrodes adjacent in the row direction; a hole transport layer in a gap between the banks; an organic light-emitting layer over the hole transport layer; and a common electrode over the organic light-emitting layer. Light is emitted from a first light-emitting portion and second light-emitting portions of the light-emitting layer. The first light-emitting portion is a portion above the pixel electrodes excluding where the insulating film is disposed. The second light-emitting portions are portions above both the pixel electrodes and the insulating film.
