To provide a constitution capable of reducing production cost in a semiconductor device for display of a type integrally formed with a drive circuit with a digital signal as an input signal and a pixel matrix unit, a signal dividing circuit is formed on a substrate where drive circuits and a pixel matrix unit are to be formed simultaneously with the drive circuits and the pixel matrix unit in view of fabrication steps by which fabrication steps of the signal dividing circuit per se and steps required for connecting the signal dividing circuit to wirings on the substrate can be dispensed with without adding further steps.
