A display driver comprises second and third MOSFETs for supplying reference currents
equal to each other, a first current-input MOSET connected to the second MOSFET,
a second current-input MOSFET connected to the third MOSFET, a plurality of mirroring
devices which are placed between the first current-input MOSFET and the second
current-input MOSFET and to which a current fed to each of the first and second
current-input MOSFETs is distributed, and current adding means for changing the
output current value by adding currents produced in the plurality of mirroring devices.
