Abstract
To provide a semiconductor display device capable of displaying an image having clarity and a desired color, even when the speed of deterioration of an EL layer is influenced by its environment. Display pixels and sensor pixels of an EL display each have and EL element, and the sensor pixels each have a light receiving diode or a sensor TFT. The luminance of the EL elements of each in the display pixels is controlled in accordance with the amount of electric current flowing in each of the light receiving diodes or sensor TFTs.
