ABSTRACT:
A polarizing plate (11) having a rightward and upward polarization angle is provided on a display screen (10), and a ½-wave plate (21) whose optical axis is at 45 deg. to said polarization angle is applied to said right half. A ½-wave plate (22) whose optical axis is orthogonal to that of said ½-wave plate (21) is applied to a right-eye side of a polarizing plate (12) (glasses) which has a leftward and upward polarization angle and which is to be worn by a viewer. Thus, images for left and right eyes can be viewed by left and right eyes through the ½-wave plates. The image for a right eye (13R) that should not enter a left eye (14L) is completely blocked by a polarization angle orthogonal thereto. The image for a left eye (13L) that should not enter a right eye (14R) is completely blocked to prevent crosstalk between the left and right images because the optical axes of the two phase difference plates (21, 22) are in an orthogonal state in which the coordinate axis is rotated 90 deg. to cancel the phase difference to realize an orthogonal light-blocking state of the polarizing plates (11, 12).
