Abstract: A display device includes a display panel including a sub-pixel, and a display panel driver for driving the display panel. The sub-pixel includes a driving transistor, a storage capacitor connected to a control electrode of the driving transistor, a write transistor writing a data voltage to the storage capacitor in response to a write gate signal, a first emission transistor providing a first power voltage to a first electrode of the driving transistor in response to a first emission signal, a hold capacitor including a first electrode receiving the first power voltage and a second electrode connected to a second electrode of the driving transistor, and a light emitting element emitting light. The first emission signal has an active level in a first portion of each of first periods of one frame, and has the active level in each of second periods respectively subsequent to the first periods.
