Abstract
A display device includes a display region arranged above a substrate, a first light emitting element emitting light of a first color, a second light emitting element emitting light of a second color, and a third light emitting element emitting light of a third color arranged in the display region, and a first optical path length adjustment film, a second optical path length adjustment film, and a third optical path length adjustment film in the display region.
Claims12
A display device comprising:
- a display region arranged above a substrate;
- a first light emitting element emitting light of a first color, a second light emitting element emitting light of a second color, and a third light emitting element emitting light of a third color arranged in the display region;
- and
- a first optical path length adjustment film, a second optical path length adjustment film, and a third optical path length adjustment film in the display region,
