A 3D display apparatus includes a 3D panel which displays a 3D image, a first circular polarization film which is attached to a front side of the 3D panel and converts the 3D image to a circular polarization component by retarding a phase, and 3D glasses including a second circular polarization film which converts the circular polarization component converted by the first circular polarization film to a linear polarization component by retarding a phase, a liquid crystal unit which allows the linear polarization component to pass or isolates the linear polarization component from passing based on a state of the power, and a linear polarization plate which allows the linear polarization component to pass or isolates the linear polarization component from passing based on a direction of the linear polarization component.
