Abstract: A display apparatus that prevents visual recognition of flickering in each of display areas having different resolutions includes a first pixel circuit, a first display element, a second pixel circuit, and a second display element. The first pixel circuit includes: a first driving transistor configured to control a first current that flows to the first display element; and a first initializing transistor configured to apply a first initializing voltage to a gate of the first driving transistor in response to a first scan signal. The second pixel circuit includes: a second driving transistor configured to control a second current that flows to the second display element; and a second initializing transistor configured to apply a second initializing voltage having a level different from a level of the first initializing voltage to a gate of the second driving transistor in response to the first scan signal.
