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.”
