PROBLEM TO BE SOLVED: To provide a differential amplification circuit which controls an amplitude difference deviation to a small level in an entire gradation area including a neighborhood of a supply voltage. SOLUTION: In the differential amplification circuit where outputs of a first differential pair (MN1 and MN2) and a second differential pair (MP1 and MP2) having different polarities each other are coupled by a link stage (10), an input pair of one differential pair of the first and the second differential pairs receives an input signal obtained from an input terminal Vin and a feedback signal obtained from an output terminal Vout each and the input pair of the other differential pair receives reference signals (Vref11 and Vref12) of a level to make a transistor pair of the other differential pair be a on-state (however, the reference signals Vref11 and Vref12 may have the same voltage).
