Abstract
A display device includes a plurality of pixels each including a first light emitting element with a first light reflecting layer, a second light emitting element with a second light reflecting layer, and a third light emitting element with a third light reflecting layer, arranged in a two-dimensional matrix. Each of the light emitting elements includes a first electrode, an organic layer, and a second electrode. Grooves that each have a light shielding layer are formed in a boundary region between the light emitting elements. A bottom of the first groove and a bottom of the third groove are located at a position higher than a top surface of the first light reflecting layer. A bottom of the second groove is located at a position higher than a top surface of the second light reflecting layer.

A display device comprising:
- a substrate;
- a plurality of transistors arranged on the substrate;
- an insulation layer disposed over the plurality of transistors;
- a plurality of light emitting elements including a first light emitting element, a second light emitting element, and a third light emitting element, the plurality of light emitting elements being arranged on the insulation layer, the plurality of light emitting elements being arranged in a two-dimensional matrix,
- a color filter comprising a first region corresponding to the first light emitting element, a second region corresponding to the second light emitting element, and a third region corresponding to the third light emitting element, the color filter being disposed at a light emission side of the plurality of light emitting elements;
- a first light shielding layer disposed between the first light emitting element and the second light emitting element;
- and
- a second light shielding layer disposed between the second light emitting element and the third light emitting element,
- wherein each of the first, second, and third light emitting elements include a light reflection layer, a light emitting layer, and a first light transparent layer, the respective light emitting layers of the first, second, and third light emitting elements extending throughout the plurality of light emitting elements,
- wherein in the first light emitting element, the light reflection layer is arranged at a first distance from the first region, in the second light emission element, the light reflection layer is arranged at a second distance from the second region, and in the third light emission element, the light reflection layer is arranged at a third distance from the third region,
- wherein the first distance, the second distance and the third distance are different, and
- wherein a distance between a lowermost surface of the first light shielding layer and an uppermost surface of the first light shielding layer is different from a distance between a lowermost surface of the second light shielding layer and an uppermost surface of the second light shielding layer.
