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.

Abstract: A display device capable of reducing a non-display area includes a substrate hole surrounded by light emitting elements, and a moisture penetration preventing layer disposed between an inner dam surrounded by the light emitting elements and the substrate hole. Accordingly, it is possible to prevent damage to light emitting stacks caused by external moisture or oxygen. Since the substrate hole is disposed within an active area, a reduction in non-display area is achieved.

Abstract: A display device capable of reducing a non-display area includes a substrate including at least one hole area disposed within an emission area, and at least one blocking hole passing through inorganic insulating films disposed beneath a light emitting element while including upper and lower insulating films made of different materials. Side surfaces of the upper inorganic insulating film exposed through the blocking hole protrude beyond side surfaces of the lower inorganic insulating film exposed through the blocking hole, respectively. Accordingly, it is possible to minimize a bezel area, which is a non-display area, and to disconnect a light emitting stack by the blocking hole.
