Abstract
There are provided 3D glasses for use in a stereoscopic display device including a display panel for emitting right-eye image light and left-eye image light and an optical filter including a first area for adjusting a polarized state of the right-eye image light and a second area for adjusting a polarized state of the left-eye image light, comprising a right-eye area allowing right-eye image light to pass therethrough and a left-eye area allowing left-eye image light to pass therethrough; and compensation films disposed at the right-eye area and the left-eye area to compensate for a phase difference deviation between the first and second areas of the optical filter, wherein a phase difference value of the compensation film provided at the right-eye area and that of the compensation film provided at the left-eye area are different.
