Abstract

A three-dimensional image display device (1) has: a liquid crystal display (3) having a first image formation region (21) and a second image formation region (22) both comprising a plurality of horizontal lines (23); and an optical means in which a first polarization region (31) and a second polarization region (32) are disposed corresponding to these image formation regions. A right eye image is displayed in the first image formation region (21) of a frame image and a left eye image is displayed in the second image formation region (22) of the frame image, and the image formation regions are alternately interchanged or are overwritten at each frame change. The boundary line (25) between the first image formation region (21) and the second image formation region (22) moves in synchronization with the timing at which the first and second image formation regions (21, 22) in which the right and left eye images are displayed are interchanged, and the phase difference states of the corresponding first polarization region (31) and second polarization region (32) of the optical means are mutually interchanged, thereby enabling the right and left images displayed by the three-dimensional image display device to be simultaneously viewed and reducing the image resolution decrease and the crosstalk.
