Abstract:
A display panel includes a second display region and a first display region which are arranged side by side in a direction in which data signal lines extend, and a source driver is provided at one edge of the second display region. Switches are provided between data signal lines in the first display region and data signal lines in the second display region, and the switches are turned off when an on-level scanning signal is applied to a scanning signal line in the second display region. A period during which the on-level scanning signal is applied to each scanning signal line in the second display region is shorter than a period during which the on-level scanning signal is applied to each scanning signal line in the first display region.
