Abstract
A Fresnel liquid crystal lens and a 2D/3D switchable display panel are provided. The Fresnel liquid crystal lens includes a plurality of liquid crystal lens units. Each liquid crystal lens unit includes a first main electrode and two first sub electrodes disposed on a first substrate, a second main electrode and two second sub electrodes disposed on a second substrate, and a liquid crystal layer disposed between the first and second substrates. The first sub electrodes are disposed on two opposite sides of the first main electrode, and a first gap is formed between the first main electrode and the first sub electrode. The second sub electrodes are disposed on two opposite sides of the second main electrode, and a second gap is formed between the second main electrode and the second sub electrode. In a vertical projection direction, the first main electrode overlaps the second main electrode, the first sub electrodes overlap the second sub electrodes, and the first main electrode partially overlaps the second sub electrodes.
