Abstract:
A liquid crystal display (LCD) comprising:an upper substrate having an upper electrode on an inner surface of the upper substrate; a lower substrate having lower electrodes respectively arranged in areas defined by gate lines and signal lines and on an inner surface of the lower substrate, an electric field being formed between the upper electrode and the lower electrodes; a liquid crystal layer with a negative anisotropy of dielectric constant filling a space between the upper substrate and the lower substrate; a plurality of first alignment-control structures arranged on the inner surface of the upper substrate, wherein a first concave is formed between two adjacent first alignment-control structures, and a first inclined plane is formed between each first concave and each first alignment-control structure; and a plurality of second alignment-control structures arranged on the inner surface of the lower substrate, wherein a second concave is formed between two adjacent second alignment-control structures, and a second inclined plane is formed between each second concave and each second alignment-control structure; wherein, the first alignment-control structures and the second alignment structures are alternately arranged on the intersections of the gate lines and the signal lines; wherein each first alignment-control structure is positioned above a corresponding second concave, each second alignment-control structure is positioned under a corresponding first concave, the first alignment-control structure and the corresponding second concave have a first substantially equal size, the second alignment-control structure and the corresponding first concave have a second substantially equal size, and the first inclined plane faces the second inclined plane.
