Abstract: A display apparatus includes pixels connected to scan lines, data lines, and emission control lines. Each include includes an organic light-emitting diode (OLED), a first transistor to transfer driving current to the OLED based on a data signal, a second transistor to transfer the data signal to the first transistor based on a first scan signal having a gate-on voltage level during a data writing period, a first capacitor connected between a gate electrode of the first transistor and a first power source, and a second capacitor connected between a drain electrode of the first transistor and the first power source.
