Abstract
An organic electroluminescence (EL) display panel including pixels arranged in a matrix, the organic EL display panel includes: a substrate; pixel electrode layers made of a light-reflective material and arranged on the substrate in a matrix; an insulating layer provided at least above row and column outer edges of the pixel electrode layers and above inter-regions on the substrate between the row and column outer edges; an organic functional layer provided above the pixel electrode layers; and a counter electrode layer made of a light-transmissive material and is provided above the organic functional layer, wherein the organic functional layer includes light-emitting layers that are provided in regions above the pixel electrode layers where the insulating layer is not provided, the light-emitting layers causing organic electroluminescence, and the insulating layer has an optical density of 0.5 to 1.5 in a direction of the substrate when viewed in plan.
