The invention discloses a light field display device. The light field display device comprises multiple groups of imaging modules, wherein each group of imaging modules includes a liquid crystal lens array and a display screen, wherein the liquid crystal lens array is arranged on the light emergency side of the display screen, and images formed by the multiple groups of imaging modules are parallel mutually. The refresh frequency requirements of the display screens and the liquid crystal lens arrays can be reduced and accordingly the response time requirement is reduced by adopting the light field display device.
