Abstract: A display device includes a substrate on which an active region and a non-active region disposed are defined. The non-active region at least partially surrounds the active region. A light-emitting element is disposed in the active region on the substrate. An encapsulation layer is disposed on the light-emitting element. Block patterns are disposed in the non-active region on the substrate and at least partially surround the active region. The non-active region includes a first non-active region positioned at a first side of the active region and a second non-active region positioned at a second side of the active region. There are more block patterns disposed in the first non-active region than in the second non-active region.
