Patent abstract

A liquid crystal display panel includes an array substrate, an opposite substrate having an opposite electrode, a liquid crystal layer located therebetween, first alignment patterns and second alignment patterns. The array substrate includes scan lines, data lines and pixel units electrically connecting corresponding scan lines and data lines. Each pixel unit includes a first active device, a first pixel electrode electrically connecting the first active device and a second pixel electrode. The first pixel electrode and the second pixel electrode are separated to define a first displaying region and a second displaying region. The extending directions of the first alignment patterns in the first displaying region and the second alignment patterns in the second displaying region respectively intersect the extending direction of the scan lines at a smaller first acute angle and a greater acute angle for controlling the arrangements of the liquid crystal molecules.
