Abstract

A stereoscopic image display apparatus of this invention includes a half mirror having a ½ wavelength plate and a half mirror layer. Therefore, a direction of polarization of light incident on a surface of a transmission side of the half mirror can be rotated and emitted. This can be manufactured at lower manufacturing cost than a construction having the ½ wavelength plate on the front display plane of one of the two image display devices with linear polarization plates having the same polarizing direction, or preparing two image display devices with linear polarization plates having different polarizing directions. A high-quality stereoscopic image can be observed by adjusting the orders and positions of sub-pixel colors of the two image display devices at the time of composition and display through the half mirror.
