Abstract: A display device includes: a memory, a driving controller, a light emitting element, a first transistor including a first electrode, a second electrode, and a gate electrode for receiving a data signal, a second transistor connected between a first driving voltage line and the first electrode of the first transistor and receiving a first emission signal, and a third transistor connected between the second electrode of the first transistor and the light emitting element and receiving a second emission signal. The first emission signal includes a compensation period and an emission period, and the memory stores instructions that, when executed by the driving controller, cause the driving controller to determine a compensation time of the compensation period depending on target luminance.
