Abstract: The present invention provides a liquid crystal display panel, which comprises a plurality of display blocks sequentially arranged in an array. Each of the display blocks comprises a plurality of pixel units, each of which has two display regions. The pixel units are classified into a first type of pixel units and a second type of pixel units. The pixel units of different types have different liquid crystal alignment directions or different gray-level brightness, or both of the liquid crystal alignment directions and the gray-level brightness are different for different types of pixel units. The liquid crystal display panel of the present invention has high display brightness, large viewing angle, and low manufacturing cost.
