Abstract: A display apparatus includes a substrate including a trench portion, a display area, and a non-display area. The non-display area includes a first non-display area. The display area includes a main area and first and second display areas protruding from the main area. The first non-display area and the trench portion are between the first and second display areas. The display apparatus further includes: first scan lines transmitting scan signals to pixels in the first display area; second scan lines transmitting scan signals to pixels in the second display area; connection scan lines in the first non-display area and connecting the first scan lines and the second scan lines; and driving voltage lines transmitting driving voltages to pixels in the main area. A plurality of first driving voltage lines among the driving voltage lines extend to the first non-display area, and overlap the plurality of connection scan lines.

Abstract: A display panel includes a base substrate in which an active area and a peripheral area adjacent to the active area are defined, a pixel disposed in the active area, a first line disposed in the active area and connected to the pixel, a second line disposed in the peripheral area and spaced apart from the first line in a plan view, a linking pattern electrically connecting the first line to the second line and disposed on a layer different from a layer on which each of the first and second lines is disposed, and an inorganic layer disposed between the first line and the linking pattern and between the second line and the linking pattern. The linking pattern is connected to the first line and the second line through contact holes formed in the inorganic layer.
