Abstract
A liquid crystal projector which projects a three-dimensional imaged based on image signals for the left and right eyes including: a liquid crystal panel into which an image for the left or right eye is written in a one-field time period based on the image signal; an optical shutter has a plurality of divisional regions arranged in a vertical direction and controllable independently in regard to whether or not light should be blocked; a polarizing element has a plurality of divisional regions arranged in vertical direction and controllable independently in regard to whether the polarization direction should be set to that for the left eye or the right eye; and a control circuit controls the optical shutter and the polarizing element in synchronism with a writing position in the liquid crystal panel.
