Claim 16:
17. A display device comprising:
pixel circuits provided in a matrix shape in a display region;
a scanning signal line, a data signal line, a first power supply voltage line, and a second power supply voltage line connected to the pixel circuits;
a scanning signal line drive circuit configured to apply a voltage to the scanning signal line;
a data signal line drive circuit configured to apply a voltage to the data signal line; and
a display control unit configured to control the scanning signal line drive circuit and the data signal line drive circuit,
wherein the pixel circuits include a display element, a holding capacitor, and a drive transistor, and are configured, when the scanning signal line is selected, such that a voltage of the data signal line corresponding to the selected scanning signal line is written in the holding capacitor as a data voltage,
the drive transistor includes a first conduction terminal connected to the first power supply voltage line, a second conduction terminal connected to the second power supply voltage line through the display element, and a control terminal connected to the first power supply voltage line through the holding capacitor,
the display control unit compares data values written in pixels in an n-th row corresponding to the selected scanning signal line with data values written in pixels in an (n−1)-th row being one row prior to the n-th row of the selected scanning signal line, and corrects the data voltage corresponding to the pixels in the n-th row in a case where a difference between the data values is equal to or greater than a threshold value, and
the display control unit includes a plurality of correction tables in which an amount of correction for the data voltage is set, and selects one of the plurality of correction tables based on the difference between the data values.
