Abstract
An organic EL display panel includes a substrate, an interlayer insulation layer formed over the substrate, and an organic EL light emitting section formed over the interlayer insulation layer. The organic EL light emitting section includes a plurality of pixel electrodes arranged in a matrix pattern, a plurality of partition walls each of which is disposed between the pixel electrodes adjacent to each other in a row direction and extends in a column direction, an organic layer including a light emitting layer formed in a region partitioned by the partition walls, and a counter electrode formed on an upper side of the organic layer, and includes a first light emitting section for a first color and a second light emitting section for a second color. The first and second light emitting sections are different in thickness of the organic layer and in digging amount of the interlayer insulation layer in the region partitioned by the partition walls.
