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.
