  • Publication number: 20220416206
    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.
