Abstract:
An organic EL display panel including pixels arranged in a matrix includes: a substrate; pixel electrodes arranged above the substrate in the matrix; an insulating layer provided above the pixel electrodes and having openings for each pixel electrode; banks extending in a column direction and partitioning between the pixel electrodes in a row direction; organic functional layers provided above the pixel electrodes and including organic light emitting layers where organic electroluminescence occurs in the openings; and a light-transmissive counter electrode provided above the functional layers. The openings include: first openings arranged in line in the column direction; and a second opening adjacent to one of the first openings in the row direction. Portions of the insulating layer between the first openings adjacent in the column direction are lower in height relative to the pixel electrode than a portion of the insulating layer between the first opening and the second opening.
