Abstract

Provided is a display device in which more than one pixel is arranged in a two-dimensional matrix on a circuit board, the pixel including a light emission unit including a first electrode, an organic layer, and a second electrode that are stacked, in which the first electrode is disposed for each light emission unit, and a partition is formed between the first electrode and an adjacent first electrode, the organic layer and the second electrode are stacked on an entire surface including the first electrode and the partition, the first electrode is formed on an interlayer insulation film, and a reflection film is formed below the first electrode, the reflection film including a light reflecting surface disposed to be flush with a boundary plane on which different insulation materials are in contact with each other in the interlayer insulation film.
