THREE-DIMENSIONAL VIDEO DISPLAY DEVICE AND POLARIZING GLASSES FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a useful 3D video display device by which gives video which is sharp and has strong three-dimensional feeling. SOLUTION: The 3D video display device consists of a 3D video display body S provided with a polarization plate 2 in front of a video display part 1 and provided with a 3D video display part 3 the optical main axis direction of which has a prescribed angle with respect to the transparent axis direction of the plate 2 and where a video display part (a) for a right eye having a phase difference function and a video display part (b) for a left eye having no phase difference function coexist in front of this plate 2; and polarization classes T consisting of a lens 4a for the right eye with the polarization plate transmitting video for the right eye from the part (a) and cutting off video for the left eye from the part (b) and a lens 4b for the left eye with the polarization plate transmitting video for the left eye from the part (b) and cutting off video for the right eye from the part (a). A phase difference function member 5 having the optical main axis in a direction orthogonal to the optical main axis of the part (a) and having a phase difference function is stuck to the front of the lens 4b.
