Abstract:
A display device includes a data line to which a data voltage is applied, a first driving voltage line to which a first driving voltage is applied, a second driving voltage line to which a second driving voltage is applied, and a pixel connected to the first and second driving voltage lines. The pixel includes a first transistor to control a driving current according to a voltage applied to a first node, a light emitting element between the first transistor and the first driving voltage line, and a capacitor between the first node and the second driving voltage line. The first driving voltage has a first high-level voltage during a first initialization period, the first driving voltage has a first mid-level voltage lower than the first high level voltage during a threshold-voltage-storage period, and the first driving voltage has a first low-level voltage during a second initialization period.
