Abstract: A liquid crystal display panel and a display device are provided. A first metal line is disposed on a first substrate of the liquid crystal display panel. An orthographic projection of the first metal line on a pixel electrode covers a first trunk electrode. A voltage difference V1 between the first metal line and a common electrode is small, so that a liquid crystal molecule corresponding to the first metal line does not deflect. In this way, a problem of an insufficient liquid crystal recovery force when the liquid crystal display panel is pressed is resolved, eliminating poor liquid crystal diffusion as a result of pressing and resulting in improving display quality.

Abstract: The present invention provides a liquid crystal display (LCD) panel, a display module, and an electronic device. The LCD panel includes predetermined electrodes connected to power supply voltages. A sub-display region includes at least one pixel column and is arranged corresponding to at least one of the predetermined electrode. The power supply voltages connected to the predetermined electrodes in the same sub-display region are equal. The power supply voltage in the sub-display region located in the middle of the LCD panel is different from the power supply voltages in the sub-display regions located on two sides of the LCD panel.
