The present invention achieves a display device capable of quick compensation of charging of parasitic capacitance with a simple configuration and low power consumption. The display device in accordance with the present invention includes (i) pixels, (ii) signal wires (Sj), and (iii) an operational amplifier (OP1) having a non-inverting input terminal connected with a corresponding signal wire (Sj). The operational amplifier (OP1) is configured such that: the non-inverting input terminal is connected with an output terminal (OUT) via a first impedance element (R1); an inverting input terminal is connected with the output terminal (OUT) via a second impedance element (R2); and the inverting input terminal is connected with a reference voltage terminal via a third impedance element (Cn). A value Zn of total impedance of pixels electrically connected with the corresponding signal wire, which impedance is obtained while the corresponding signal wire and the pixels electrically connected with the corresponding signal wire are being supplied with an image signal, is represented by |Zn|<|Z1|·|Z3|/|Z2|, where Z1, Z2, and Z3 are values of impedance of the respective first through third impedance elements (R1, R2, and Cn). |
