Abstract

A liquid crystal lens and a 3D display device are provided. The liquid crystal lens comprises a lower substrate, an upper substrate disposed opposite to the lower substrate and a common substrate disposed between the upper substrate and the lower substrate. A plurality of first lenses are disposed between the lower substrate and the common substrate, each of the first lenses only converging light component of the incident natural light in a first polarization direction. A plurality of second lenses are disposed between the upper substrate and the common substrate, each of the second lenses only converging the light component of the incident natural light in a second polarization direction different from the first polarization direction. The 3D display device of the invention can reduce loss of light energy and enhance display luminance of the 3D display device as a whole.
