Abstract
A stereoscopic image display device capable of reducing grid visual effect includes a flat display unit, a light source unit disposed on a side of the flat display unit, and a lens array unit disposed on another side of the flat display unit. A light source provided by the light source unit satisfies an optical characteristic as follows: an attenuation amplitude of a luminance of the light source before entering the lens array unit being not greater than 65% within a divergence angle of a light field system of the stereoscopic image display device, thereby reducing the grid visual effect of a stereo image generated by the stereoscopic image display device.
