Abstract
A display device comprises a substrate in which a first subpixel and a second subpixel arranged to adjoin the first subpixel are defined, a first electrode provided in each of the first subpixel and the second subpixel on the substrate, a light emitting layer provided in each of the first subpixel and the second subpixel on the first electrode, a second electrode commonly provided in the first subpixel and the second subpixel on the light emitting layer, a trench portion provided between the first subpixel and the second subpixel, and an insulating portion filling at least a part of the trench portion.

A display device comprising:
- a substrate in which a first subpixel and a second subpixel adjacent to the first subpixel are defined;
- a first electrode provided in each of the first subpixel and the second subpixel on the substrate;
- a light emitting layer provided in each of the first subpixel and the second subpixel on the first electrode;
- a second electrode commonly provided in the first subpixel and the second subpixel on the light emitting layer;
- a bank provided to cover ends of the first electrode;
- a trench portion provided between the first subpixel and the second subpixel;
- and
- an insulating portion filling at least a portion of the trench portion,
- wherein the light emitting layer provided in the first subpixel and the light emitting layer provided in the second subpixel include sidewalls formed in an area overlapping with the trench portion to face each other.
The display device of 1, further comprising a lens array spaced apart from the substrate, and a storage case for storing the substrate and the lens array.
A display device comprising:
