1. A display device comprising:
pixels divided into pixel rows arranged in a horizontal direction, and comprising a light emitting element, and a first transistor for applying a drive current to the light emitting element; and
a sensing driver configured to receive a sensing value extracted from one or more of the pixels,
wherein at least one pixel row of the pixel rows is configured to be driven in one frame comprising an emission period in which the light emitting element emits light after a data voltage is applied to the pixels, and an active sensing period for sensing a characteristic of the first transistor after the data voltage is applied to the pixels.
