Abstract
Pixels each including a light emitting unit formed by laminating a first electrode, an organic layer, and a second electrode are arranged in a two-dimensional matrix. The organic layer includes multiple light emitting layers of different types and a light emission separation layer. Each of the multiple light emitting layers of different types is laminated as a common layer extending continuously over the pixels. The light emission separation layer is arranged between two adjacent light emitting layers, and is formed so as to have a different configuration depending on a display color of the pixel.
