Patent ID: 8125583

Claim:
A stereoscopic image display apparatus comprising: a first image display device including a first display unit for displaying a first image which is either one of an image for the left eye and an image for the right eye, and a first linear polarization plate disposed on a front plane of the first display unit and having either one of vertical and horizontal polarizing directions; a second image display device disposed in a position for forming an angle with the first image display device, and including a second display unit for displaying a second image different from the first image, which is either one of the image for the left eye and the image for the right eye, and a second linear polarization plate disposed on a front plane of the second display unit and having the same polarizing direction as the first linear polarization plate; and a half mirror extending from a corner of the first image display device and the second image display device to an area between the first image display device and the second image display device, having functions to transmit light of the first image displayed on the first image display device and to reflect light of the second image displayed on the second image display device, and including, as arranged in order from an incidence side of a plane for transmitting the light of the first image, a polarized light rotating layer for rotating a direction of polarization of the light having undergone linear polarization, and a half mirror layer.
