Abstract: A lens assembly including an incident side on which light is incident and an exit side opposite to the incident side, includes: a first polarization layer disposed adjacent to the incident side; a second polarization layer disposed between the first polarization layer and the exit side; a phase retardation layer disposed between the first polarization layer and the second polarization layer. The phase retardation layer has a first phase retardation refractive index along a first direction, has a second phase retardation refractive index equal to the first phase retardation refractive index along a second direction, and has a third phase retardation refractive index along a third direction perpendicular to the first direction and the second direction, and the first phase retardation refractive index and the second phase retardation refractive index are different from the third phase retardation refractive index.
