A display apparatus includes a first pixel, a second pixel, and a dummy pixel. The first pixel includes a first light-emitting device connected to a first pixel circuit through a first node. The second pixel is in a same row as the first pixel and includes a second light-emitting device connected to a second pixel circuit through a second node. The dummy pixel includes at dummy pixel circuit with a third node. The controller outputs a first control signal having a first level or a second level based on a first pixel grayscale value corresponding to the first pixel and a second pixel grayscale value corresponding to the second pixel. A switch circuit electrically connects the first node, the second node, and a third node when the first control signal has the first level.
