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 substrate, a thin-film transistor, an insulating material stack, and a first dam structure. The substrate includes a display area and a peripheral area located outside the display area. The thin-film transistor layer overlaps the substrate. The insulating material stack overlaps the peripheral area. The first dam structure overlaps the substrate, is located closer to the display area than the insulating material stack, partially covers the insulating material stack, and reaches farther than the insulating material stack with reference to the substrate.
