Abstract
A liquid crystal display panel and a display device are disclosed. The liquid crystal display panel includes an array substrate and an upper substrate arranged opposite to each other, and a liquid crystal layer, a spacer layer including primary spacers and secondary spacers, and a black matrix layer over the spacer layer. The overlapping area between one of the plurality of black matrix elements and a green sub-pixel near one of the plurality of primary spacers below said matrix element forms a first overlap area, wherein an overlapping area between one of the plurality of black matrix elements and a green sub-pixel near one of the plurality of secondary spacers below said matrix element forms a second overlap area; and the first overlap area equals the second overlap area.
