A light emitting element has a property in which a current value is varied due to a change in temperature. A display device has a temperature compensation function in order to suppress the variation in current value dues to the change in temperature. The temperature compensation function, which is essential for the present invention has a sensor, a storage means, and a correction means. The sensor has a function of detecting an environmental temperature. The detected temperature is compared with data of voltage-current characteristic versus temperature in the light emitting element which is stored in advance in the storage means. In the correction means, a signal inputted to a pixel or a power source potential supplied to a pixel portion is corrected using an output of the sensor and the data stored in the storage means.
