Abstract
A display device includes: a light emitting layer configured to emit light in accordance with current; a first pixel separation film configured to define a first opening for providing a light emitting region when the light emitting layer emits light; and a second pixel separation film laminated on the first pixel separation film and configured to define a second opening that is restricted so as not to gradually become wider as apart from a surface contacted with the first pixel separation film.
Claims7
A display device comprising:
- a light emitting layer configured to emit light in accordance with current applied thereto;
- a first pixel separation film configured to define a first opening for providing a light emitting region through which the light emitting layer emits light;
- and
- a second pixel separation film laminated on the first pixel separation film and configured to define a second opening through which the light is emitted,
- wherein,
- the second pixel separation film includes oppositely facing first and second surfaces and a side surface extending between the first and second surfaces,
- the first surface of the second pixel separation film is in contact with the first pixel separation film,
- the side surface of the second pixel separation film is in contact with the light emitting layer,
- the second opening of the second pixel separation film is wider than the first opening, and
- the second opening of the second pixel separation film is wider at the first surface contacted with the first pixel separation film than at the second surface.
