Abstract
The present invention provides active shutter glasses, passive glasses, and a stereoscopic image projection system, with which a viewer wearing polarizing sunglasses can enjoy improved visibility. The active shutter glasses comprises: a shutter for a right eye; and a shutter for a left eye, wherein the shutters for a right eye and for a left eye each have a liquid crystal cell and a linearly polarizing element, the linearly polarizing element is provided in each shutter on an inner side than the liquid crystal cell is, the linearly polarizing element has a transmission axis direction set in the vertical direction when the glasses are worn.
