A current output type of semiconductor circuit, a display driver device, a display device and a current output method that can restrain an increase of circuit scale even if the output bit number of a current driver is increased. The current output type of semiconductor circuit comprises a first current source group (241a,241b) that has first unit transistors for outputting a predetermined current and that outputs lower-order N bits (where N is a natural number); and a second current source group (242a,242b,242c,242d,242e,242f) that has second unit transistors for outputting a current larger than the first unit transistors and that outputs upper-order M bits (where M is a natural number, (N + M) >= 3). ® KIPO & WIPO 2008 |
