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.

A display device in which pixels each including a light emitting unit formed by laminating a first electrode, an organic layer, and a second electrode are arranged is a two-dimensional matrix, wherein:
- the organic layer includes a plurality of light emitting layers of different types and a light emission separation layer;
- each of the plurality of light emitting layers of different types is laminated as a common layer extending continuously over the pixels;
- and
- 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.
A manufacturing method of a display device in which 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 method comprising the steps of
- forming the first electrode so as to correspond to each pixel, and
- laminating each of a plurality of light emitting layers of different types as a continuous common layer on an entire surface including the first electrodes, and forming a light emission separation layer arranged between two adjacent light emitting layers, so that a configuration of the light emission separation layer differs depending on a display color of the pixel.
An electronic instrument comprising
- a display device in which 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, wherein:
