A display device in which a plurality of pixels are arranged in an array is provided. Each of the plurality of pixels comprises a current path that includes a light emitting element and a first transistor, and a second transistor for transmitting a luminance signal. The first transistor comprises diffusion regions arranged in the current path, and a gate electrode to which the luminance signal is transmitted from the second transistor. The diffusion regions are of a first conductivity type, and the gate electrode is of a second conductivity type opposite to the first conductivity type.
