Abstract
A display device includes a display panel including a pixel, a temperature sensor which senses a temperature of the display panel and outputs the temperature of the display panel as a sensing temperature, a first compensation part which receives a gate-source voltage sensed in the pixel as a sensing voltage and compensates for the sensing voltage by a change amount of the gate-source voltage corresponding to a difference value between a reference temperature and the sensing temperature, and a second compensation part which compensates for data to be applied to the pixel by comparing a compensated sensing voltage with an initial gate-source voltage.
