PROBLEM TO BE SOLVED: To provide a stereoscopic image display device capable of observing excellent stereoscopic images by preventing moire fringes from being observed on a display device. SOLUTION: In this stereoscopic image display device provided with a light source means 11 for emitting a patterned luminous flux in a prescribed shape, an optical system where an optical action is different in a horizontal direction and a vertical direction and the display device 1 for displaying a stripe image for which the stripe pixels of a parallactic image for a right eye and the parallactic image for a left eye are alternately arranged in a prescribed order at the display device 1, giving directivity to the patterned luminous flux in the optical system, irradiating the stripe image, separating the luminous flux into two areas and making an observer visually recognize the stripe image as the stereoscopic image, the horizontal pitch Hi of the patterned luminous flux and the horizontal pixel pitch Hd of the display device 1 are made different for more than a predetermined value DH. |
