Display device and method of driving the same

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 the pixels,
• wherein at least one pixel row of the pixel rows is configured to be driven to comprise 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 during a first frame,
