Abstract

The invention provides a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel comprises a first substrate, a second substrate opposite to the first substrate and a first liquid crystal layer located between the first substrate and the second substrate. The liquid crystal display panel further comprises a dimming layer located on the side, close to the first substrate, of the second substrate, and the dimming layer comprises a plurality of shading pieces arranged at intervals; and a first light switching layer which is positioned on one side, far away from the first substrate, of the second substrate, and the first light switching layer can control the visual angle of emitted light. By arranging the dimming layer, the purpose of shrinking the visual angle can be achieved; and meanwhile, the first light switching layer is additionally arranged, and electric fields are applied to the two sides of the first light switching layer, so that free switching of wide and narrow viewing angles of the liquid crystal display panel can be realized, and a peep-proof function can be realized.
