Abstract: A display apparatus (1000) according to an embodiment can include a first electrode (400), a plurality of organic layers, a second electrode (700), and a metal layer (600) disposed on a particular organic layer (POL) among the plurality of organic layers. The metal layer (600) is configured to protect the particular organic layer (POL) from being damaged when it is exposed to a non-vacuum environment at least once during processes of stacking the organic layers on the first electrode and the second electrode (700) on the organic layers in a vacuum environment, thereby suppressing a rise in the driving voltage of the display apparatus. Accordingly, the problems that the driving voltage of the display apparatus increases and the lifespan is shortened can be addressed.

Abstract: Provided is a touch display device having a hole (H1, H2) provided in an active area (AA). Touch electrodes (TE) are disposed in at least a portion of the active area (AA), in which the hole (H1, H2) is provided and no images are displayed. The touch electrodes (TE) disposed in surrounding areas of the hole (H1, H2) are easily connected. In a case in which a plurality of holes (H1, H2) are disposed in the active area (AA), a structure disposed in the area between the holes (H1, H2) to increase the number of touch electrode connecting lines (X-CL, Y-CL) is provided. This structure increases capacitance-generating areas between the intersecting touch electrode lines, thereby improving the performance of touch sensing in the area between the holes (H1, H2).
