Abstract: The present application discloses a liquid crystal display panel, a method for manufacturing the liquid crystal display panel, and a curved display. The liquid crystal display panel is configured with an alignment layer only on an array substrate, but not on an opposing substrate opposite to the array substrate. After photo-alignment, a pretilt angle of liquid crystal molecules near the array substrate is greater than a pretilt angle of liquid crystal molecules near the opposing substrate to effectively mitigate a problem of “black clusters.”

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.
