Abstract
A display panel includes a light emitting element layer comprising a pixel definition layer having an opening defined therethrough and a light emitting element disposed in the opening. The pixel definition layer includes a first barrier portion and a second barrier portion spaced apart from each other in a first direction to define a first space having a first length in the first direction. A first inorganic layer covers the light emitting element layer. The first inorganic layer includes an uneven upper surface corresponding to the first space. An organic layer is in contact with an upper surface of the first in layer. A first groove is defined by the upper surface of the first inorganic layer overlapping the first space. A thickness of the first inorganic layer overlapping the first space varies. The organic layer is filled in the first groove.
