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 device includes a transmission area in a display area and includes a groove in a non-display area surrounding the transmission area and may minimize the occurrence of defective pixels because a groove forming process includes a process of forming a protection layer covering an emission area before formation of a mask layer and a process of removing the protection layer after removal of the mask layer.

Abstract: A display apparatus includes an encapsulation layer, a display device, a touch layer, and an organic insulating layer. The encapsulation layer is on and covers the display device. The touch layer is above the encapsulation layer and includes a plurality of sensing electrodes, each of which includes a conductive layer having a first metal layer, a second metal layer above the first metal layer, and a third metal layer between the first metal layer and the second metal layer and exposed side surfaces. The organic insulating layer is above and covers the touch layer and is spaced apart from the side surfaces of the third metal layer.
