Abstract
The present disclosure provides a liquid crystal lens, comprising: an upper substrate, a lower substrate, and both a liquid crystal layer and spacers disposed between the upper substrate and the lower substrate; wherein the surfaces of the spacers are coated with λ/4 phase retardation film. Via the method of disposing a λ/4 phase retardation film on the surface of the spacers in the present disclosure, a part of light emitting into the λ/4 phase retardation film cannot be reflected from the film and then further decreasing leaking light caused from reflective light of spacers to achieving objects of increasing the contrast of the picture and improving 3D displaying efficiencies.
