A liquid crystal lens and a display device are provided. The liquid crystal lens includes: a first substrate and a second substrate arranged opposite to each other; a liquid crystal layer, located between the first substrate and the second substrate; a plurality of strip-shaped first electrodes, parallel to each other and located on a side of the first substrate facing the liquid crystal layer; a first alignment layer, located on a side of the first electrodes facing the liquid crystal layer; a planar second electrode, located on a side of the second substrate facing the liquid crystal layer; and a second alignment layer, located on a side of the second electrode facing the liquid crystal layer, wherein an included angle between an extending direction of each of the first electrodes and one edge (a) of the first substrate is greater than zero, a rubbing direction of the first alignment layer and a rubbing direction of the second alignment layer are symmetric with respect to the extending direction of the first electrode, thereby ensuring that a liquid crystal lens with better symmetry can be acquired under smaller moiré pattern.
