Display device

A display device that displays an image by writing a data signal into a plurality of pixel circuits arranged in a display panel, wherein

• the display panel includes:
• a plurality of data signal lines configured to transmit the data signal;
• a plurality of scanning signal lines intersecting the plurality of data signal lines;
• the plurality of pixel circuits provided at intersecting portions of the plurality of data signal lines and the plurality of scanning signal lines, the plurality of pixel circuits forming a pixel matrix of a plurality of rows x a plurality of columns;
• a data signal line drive circuit configured to apply the data signal to the plurality of data signal lines;
• a scanning signal line drive circuit configured to apply a scanning signal to the plurality of scanning signal lines;
• and
• a first display region and a second display region in which the plurality of data signal lines are disposed,
• the first display region and the second display region are arranged side by side in a direction in which the plurality of data signal lines extend,
• each of the plurality of data signal lines includes a first data signal line disposed in the first display region and a second data signal line disposed in the second display region,
• the plurality of scanning signal lines include a plurality of first scanning signal lines disposed in the first display region and a plurality of second scanning signal lines disposed in the second display region,
• the data signal line drive circuit is provided at one edge of the second display region so that the data signal is applied to the second data signal line earlier than the first data signal line,
• the display panel further includes a first switching element provided for each of the plurality of data signal lines, the first switching element having a control terminal to which a first switching signal is provided, a first conductive terminal connected to the first data signal line,
• and a second conductive terminal connected to the second data signal line, when the scanning signal line drive circuit applies an on-level scanning signal to any of the plurality of first scanning signal lines, the first switching element is in an on state,
• when the scanning signal line drive circuit applies an on-level scanning signal to any of the plurality of second scanning signal lines, the first switching element is in an off state,
