Abstract: An organic light emitting display device includes a substrate, an insulation layer structure, a light emitting layer, and an optical module. The substrate has an opening region, a peripheral region surrounding the opening region, and a display region surrounding the peripheral region. An opening is defined through the substrate in the opening region. The insulation layer structure is disposed in the display region and the peripheral region on the substrate. The light emitting layer is disposed on the insulation layer structure, and extends in a first direction from the display region into the opening region. A first opening is defined through the light emitting layer in the peripheral region. The optical module is disposed in the opening of the substrate.

Abstract: A display apparatus includes a display element; a substrate including: an opening area, a display area adjacent to the opening area, a non-display area between the opening area and the display area, and a boundary line separating the opening area from the non-display area; an encapsulation layer including: a first inorganic encapsulation layer, an organic encapsulation layer and a second inorganic encapsulation layer in the display area, and the first inorganic encapsulation layer and the second inorganic encapsulation layer extending from the display area to the non-display area; and a dam portion in the non-display area and corresponding to the boundary line. The dam portion which corresponds to the boundary line includes a plurality of grooves in which the first inorganic encapsulation layer and the second inorganic encapsulation layer which are in the non-display area, are in contact with each other.

Abstract: A display apparatus includes a substrate, a pixel defining layer, a spacer, an auxiliary electrode, and an organic light emitting diode. The substrate includes a light emitting area and a non-light emitting area adjacent to the light emitting area. The pixel defining layer is disposed on the non-light emitting area of the substrate. The spacer is disposed on the pixel defining layer. The auxiliary electrode is disposed on the spacer. The organic light emitting diode is disposed on the substrate, and at least a portion thereof is disposed in the light emitting area. The organic light emitting diode includes a pixel electrode, an intermediate layer disposed on the pixel electrode and including an organic light emitting layer, and an opposite electrode disposed on the intermediate layer and electrically connected to the auxiliary electrode.
