Abstract
According to one embodiment, a display panel includes scanning lines, signal lines, a pixel switching element, a pixel electrode, and a first control switch including first control switching elements. Each of the first control switching elements is composed of a transistor and includes a gate electrode, a source electrode, and a drain electrode. The scanning lines electrically connected to the gate electrodes of the first control switching elements are different from each other. The drain electrodes of the first control switching elements are electrically bundled and are connected to power source voltage output terminal of the first control switch.
