Abstract: A display device includes an initialization voltage line to which an initialization voltage is applied, a first driving voltage line to which a first driving voltage is applied, and a pixel connected to the initialization voltage line and the first driving voltage line. The pixel includes a first transistor to control a driving current flowing between a first electrode and a second electrode 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 first capacitor between the first node and the initialization voltage line. During an initialization period in which the light emitting element is initialized, the initialization voltage is changed from a first level voltage to a second level voltage lower than the first level voltage and the first driving voltage is changed from a first high-level voltage to a first low-level voltage.
