Abstract: A method of manufacturing a display apparatus includes forming a thin-film transistor on a substrate and forming a planarization layer to cover the thin-film transistor, forming, on the planarization layer, a pixel electrode electrically connected to the thin-film transistor and a pixel defining layer exposing at least a center portion of the pixel electrode, and defining at least one groove having a closed curve shape at a location corresponding to a second non-display area. When the thin-film transistor is formed, a voltage line is also formed at a location corresponding to a first non-display area. When the at least one groove is formed, a portion of the planarization layer disposed between the pad area and the display area is simultaneously removed such that a portion of the voltage line between the pad area and the display area is exposed.
