<P>PROBLEM TO BE SOLVED: To provide a stereoscopic image display device capable of reducing its manufacture cost and also observing a high definition stereoscopic image. <P>SOLUTION: The stereoscopic image display device 1 comprises a half mirror 5 having a 1/2 wavelength plate 19 and a half-mirror layer 23b. Therefore, it is possible to rotate the polarization direction of light incident upon the surface of the half mirror 5 on a transmission side and to emit the light from the half mirror. Consequently, the manufacturing cost can be reduced compared with the arrangement in which the 1/2 wavelength plate 19 is provided on a front display surface of one of two image display devices provided with linear polarization plates having the same polarization direction, or the arrangement in which two image display devices having linear polarization plates having different polarization directions are arranged. Moreover, a high definition stereoscopic image can be observed by making the sequence and positions of colors of sub-pixels identical between the two image display devices 2 and 3 when images are combined through the half mirror 5 and are displayed. <P>COPYRIGHT: (C)2011,JPO&INPIT |
