The present disclosure relates to a liquid crystal lens assembly, a liquid crystal panel, and a liquid crystal display device. The liquid crystal lens assembly includes: a liquid crystal layer, a first electrode layer having a plurality of first bar electrodes, and a second electrode layer having a plurality of second bar electrodes. The first electrode layer and the second electrode layer are both provided on a first side of the liquid crystal layer, and an extending direction of the first bar electrodes intersects with an extending direction of the second bar electrodes. The present disclosure can increase a utilization efficiency of light beams, and reduce a power consumption of the light source side.
