Abstract

The present disclosure provides a liquid crystal display panel and a display device. The liquid crystal display panel comprises a display region and a non-display region disposed around the display region, and the display region comprises a center region and edge regions located at four corners of the center region. Pixels in the liquid crystal display panel comprise a main-pixel region and a sub-pixel region, wherein the pixels comprise first pixels intersecting a boundary line between the edge regions and the non-display region, and at least two first pixels are symmetrical about a horizontal centerline. Brightness of an upper portion and a lower portion of the horizontal center line are same in the present disclosure.
