Abstract
A display device capable of reducing a non-display area is disclosed. The disclosed display device includes a first through hole not overlapping with an organic cover layer surrounding at least one hole area disposed within an active area, and a second through hole passing through a substrate. Accordingly, it is possible to minimize a bezel area, which is a non-display area, and to prevent damage to a light emitting stack caused by a stripping process.
Claims20
A display device comprising:
- a substrate including an active area and at least one hole area within the active area;
- a light emitting element disposed on the substrate;
- an organic cover layer disposed on the light emitting element and surrounding the at least one hole area;
- a plurality of thin film layers between the substrate and the organic cover layer;
- a first through hole extending through the plurality of thin film layers;
- a second through hole extending through the substrate, the second through hole overlapping the first through hole;
- touch electrodes disposed on the organic cover layer;
- a touch insulating film disposed over or beneath the touch electrodes;
- and
- a third through hole extending through the touch insulating film, the third through hole overlapping the second through hole.
