Abstract: A light-emitting display device includes an organic layer formed to be divided between adjacent subpixels through a change in structure of a bank without the provision of an additional construction, whereby it is possible to prevent lateral leakage of current.

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.
