Abstract: A display device includes: a base layer having a display area and a non-display area adjacent to the display area; a display element layer including a plurality of light emitting elements overlapping the display area; an encapsulation layer on the display element layer; a first dam in the non-display area; and a second dam in the non-display area and spaced apart from the first dam in a direction away from the display area from a boundary between the display area and the non-display area. An inorganic layer area is defined between the first dam and the second dam, and a groove is defined in the inorganic layer area.

Abstract: An organic light emitting display (OLED) device includes a substrate having a display region and a peripheral region at least partially surrounding the display region. An insulating layer structure is disposed on the substrate within both the display region and the peripheral region. The insulating layer structure includes a groove in the peripheral region. A plurality of pixel structures is disposed in the display region on the insulating layer structure. A block structure is disposed in the peripheral region so as to at least partially overlap the groove of the insulating layer structure. The block structure at least partially fills the groove of the insulating layer structure.
