Abstract
To provide a current output type semiconductor circuit and a display device which are capable of realizing a reduction in cost by reducing the number of output stages and reducing a chip area. A display device includes three reference current generating units which generate reference currents corresponding to three display colors and outputs the reference currents, a selector which outputs an optimum reference current among the outputs of the three reference current generating units according to a display color of display data in response to a changing display color switching signal, a current output unit which outputs a current corresponding to a value of the display data with respect to a current per one gradation determined by the reference currents, and a selector for distributing the output of the current output unit to respective source signal lines corresponding to the display color.
