Liquid crystal display panel and display device

The invention discloses a liquid crystal display panel and a display device. The liquid crystal display panel comprises a first polaroid, a second polaroid, a display liquid crystal layer and a regulation and control liquid crystal layer, wherein the first polaroid and the second polaroid are oppositely arranged; the absorption axis direction of the first polaroid is perpendicular to the absorption axis direction of the second polaroid. A plurality of pixel units arranged in an array are formed between the first polaroid and the second polaroid; each pixel unit comprises a display liquid crystal layer with a transmission area and a reflection area and a regulation and control liquid crystal layer connected with a voltage source, and the voltage source is configured to apply an electric field to the regulation and control liquid crystal layer and used for controlling the arrangement state of liquid crystal molecules in the regulation and control liquid crystal layer when the display panel normally displays.
