A display device capable of easily controlling the white balance of display pixels of each color without complicated circuit configuration.n n n And an EL element 60 for emitting each color by sequentially stacking the anode 61, the light emitting layer 63, and the cathode 66, and an EL element driving TFT 40 for supplying current to each EL display element. In the display device in which the display pixels 110 are arranged in a matrix, the transistor size (W / L) of the EL element driving TFT 40 connected to the display pixels 110R, 110G, 110B of each color is EL. The TFT of the green display pixel 110G having the highest luminous efficiency of the light emitting layer 63 of the device is the smallest, and is made larger in the order of the TFTs of the red and blue display pixels having low luminous efficiency. |
