Liquid crystal lens and display device

A liquid crystal lens, comprising:

• a first substrate and a second substrate arranged opposite to each other, and a liquid crystal layer located between the first substrate and the second substrate;
• wherein
• the first substrate comprises a first base substrate and a first electrode layer disposed on the first base substrate, wherein the first electrode layer is located between the first base substrate and the liquid crystal layer;
• the second substrate comprises a second base substrate and a second electrode layer disposed on the second base substrate, wherein the second electrode layer is located between the second base substrate and the liquid crystal layer;
• at least one of the first electrode layer and the second electrode layer comprises at least one sub-electrode layer, and the sub-electrode layer comprises a plurality of electrode patterns arranged in sequence, with gaps between adjacent electrode patterns;
• the liquid crystal lens further comprises at least one light compensation layer, at least part of which is filled between adjacent electrode patterns in the sub-electrode layer, and the refractive index of the light compensation layer is substantially the same as that of the sub-electrode layer.
