Liquid Crystal Lens and Liquid Crystal Glasses

A liquid crystal lens, comprising:

• a first substrate, a second substrate opposite to the first substrate, and a liquid crystal layer between the first substrate and the second substrate;
• a first electrode on a side of the first substrate that faces the second substrate, and a second electrode on a side of the second substrate that faces the first substrate;
• and
• a Fresnel lens between the first substrate and the liquid crystal layer;
• the Fresnel lens including a flat first surface and a second surface provided with a teeth profile that are arranged opposite to each other;
• and the liquid crystal layer being on a side of the second surface that is away from the first surface,
• wherein the first electrode is a continuous electrode on the second surface of the Fresnel lens.
