Display device

1. A display device comprising a plurality of pixels placed in a matrix form, each of the pixels comprising a light emitting device wherein the light emitting device comprises:

a light emissive layer configured to emit light;

a reflective electrode, disposed on a rear surface side of the light emissive layer, configured to serve as a light reflective plane and an electrode;

a transparent electrode disposed on a front surface side of the light emissive layer;

a dividing wall, disposed between the reflective electrode and the light emissive layer at a periphery part of a region where the reflective electrode is formed, covering a part of the reflective electrode;

a protective layer on a front surface side of the transparent electrode, wherein a sum thickness of the transparent electrode and the protective layer is no greater than a quarter of a wavelength of the light emitted by the light emissive layer; and

a transparent substrate disposed above the protective layer;

wherein the protective layer and the transparent substrate are spaced from one another so as to delimit a space where a gas is sealed.

2. The display device according to claim 1 , wherein the dividing wall comprises a light absorbing material.

3. The display device according to claim 1 , further comprising a contact hole configured to connect the reflective electrode to a transistor configured to drive the pixel, wherein the dividing wall covers the contact hole.
