Abstract
The present disclosure relates to a three-dimensional image system. The present disclosure suggests a three dimensional image system comprising: a display device configured to suggest a left image and a right image alternately; a liquid crystal shutter having a liquid crystal layer and configured to switch between a λ/2 phase retardation state and a 0 phase retardation state; polarized glasses including a right glass window having a first polarization axis and a left glass window having a second polarization axis. According to the present disclosure, the left image and the right image can be exactly recognized by the left eye and the right eye, respectively, without any cross-talk problem.
