    Abstract: A display device and an electronic equipment are provided. The display device includes a display panel, a backlight module, and a timing controller. By configuring pixel electrodes to have equal or approximately equal first voltages and second voltages when the backlight source is turned on or turned off, the voltages of the pixel electrodes can be prevented from being affected by the backlight. This further stabilizes a voltage difference between the pixel electrodes and the common electrode and improves brightness uniformity of the display panel.

    Abstract: A display panel is disclosed. A thin film transistor in a non-display area is provided with a protruding structure, and a source and drain electrode layer is disposed on the protruding structure. A source electrode and a drain electrode of the source and drain electrode layer both cover a first surface, a first side wall, and a second side wall of the protruding structure. A channel width of the thin film transistor is increased, and a ratio of the channel width to a channel length of the thin film transistor is increased. Therefore, a current of the thin film transistor is increased, a charging rate of the thin film transistor is improved, and a display performance of a display panel is improved.
