Liquid crystal display device

The utility model discloses a liquid crystal display device. The liquid crystal display device comprises a liquid crystal display panel and a visual angle control box located on the light incident side of the liquid crystal display panel. The visual angle control box is divided into a plurality of visual angle adjusting areas and comprises a first substrate and a second substrate which are oppositely arranged, a dye liquid crystal layer located between the first substrate and the second substrate and a control electrode set. Wherein the dye liquid crystal layer comprises liquid crystal molecules and dye molecules dispersed among the liquid crystal molecules; the control electrode group comprises a plurality of sub-electrode groups in one-to-one correspondence with the plurality of view angle adjusting areas; each sub-electrode group is used for independently controlling the rotation direction and rotation angle of liquid crystal molecules and dye molecules in the dye liquid crystal layer of the view angle adj
