Abstract: A display device includes: a pixel including a light emitting element and a first transistor for applying a driving current to the light emitting element; a data driver for supplying a first data voltage corresponding to first sensing data to the pixel in a sensing period, and supplying, to the pixel, a second data voltage corresponding to second sensing data or a third data voltage corresponding to third sensing data in a verification period for detecting compensation degree of the sensing period; a sensing unit for extracting a first sensing value corresponding to the first sensing data, a second sensing value corresponding to the second sensing data, and a third sensing value corresponding to the third sensing data through sensing lines; and a timing controller for generating image data compensated using the first sensing value, and detecting the compensation degree using the second sensing value or the third sensing value.
