ABSTRACT:
A display includes a substrate provided with a display region and a non-display region. A plurality of display electrodes are arranged on the substrate. A plurality of switching elements are respectively connected to the display electrodes. Each of the switching elements includes a control electrode and a data electrode. A plurality of scan lines are respectively connected to the control electrodes of the switching elements. A plurality of data lines are respectively connected to the data electrodes of the switching elements. A scan line electrostatic protection and test circuit is provided in the non-display region and connected to the scan lines The scan line electrostatic protection and test circuit includes an electrostatic protection circuit provided with a protection element which is normally in a non-conduction state and is set in a conduction state by generated static electricity, and an inspection circuit to inspect a conduction state of the scan lines by way of the protection element.
