Display device and electronic device

A display device comprising:

• a display unit having a plurality of pixels each including a light emitting element and a transistor for driving, and a scan line, a signal line, a power supply line and a gate line connected to each of the pixels;
• a scan line drive circuit applying a selection pulse for sequentially selecting the plurality of pixels, to the scan line;
• and
• a signal line drive circuit writing a video signal to a pixel selected by the scan line drive circuit by applying a video signal voltage to the signal line,
• wherein the transistor for driving is disposed on a path between the power supply line and the light emitting element, in each of the pixels, and
• gate voltage for correction to be applied to a back gate of the transistor for driving via the gate line is set individually in each of unit regions in the display unit.
