Claim 0:
1. 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 data values are values obtained by extracting a portion of a gray scale data indicating a gray scale in each of the pixels.
