To provide an electronic device capable of suppressing a luminous amount of an EL element and realizing a large number of gray-scale levels. The electronic device is characterized in that the luminescence of the EL element is controlled by a pair of EL driver TFTs, one of the pair of EL driver TFTs is controlled by one of the pair of switching TFTs and one of the pair of eliminating TFTs, the other of the pair of EL driver TFTs is controlled by the other of the pair of switching TFTs and the other of the eliminating TFTs, and gray-scale display is performed by controlling the luminescence time of the EL elements.
