Abstract
The present disclosure provides a liquid crystal lens and a display apparatus. The liquid crystal lens includes a first substrate and a second substrate arranged to be opposite to each other, a common electrode being provided on the second substrate; a liquid crystal layer interposed between the first and second substrates and including liquid crystal molecules; liquid crystal lens units, each of which includes a first group of strip-shaped electrodes and a second group of strip-shaped electrodes parallel to each other and spaced apart thereon, upon applying a voltage among the first and second groups, and the common electrode, a planoconvex lens is formed within the liquid crystal molecules between them, wherein each of the first and second groups includes layers of sub-electrodes insulated from each other, the sub-electrodes of the first and second groups are applied with a voltage, so as to adjust symmetry of the planoconvex lens.
