Abstract
A stereoscopic image display device is provided and includes a flat panel display unit, a lens array unit, and a spacer unit. The flat panel display unit has a display surface. The lens array unit includes at least one condenser lens, which is disposed on a side of the display surface. The spacer unit is disposed between the display surface and the condenser lens, such that the lens array unit and the flat panel display unit are spaced apart from each other. In a light field system of the stereoscopic image display device, an object distance between the display surface of the flat panel display unit and the condenser lens of the lens array unit is configured to enable an absolute value of a central depth plane (CDP) of the stereoscopic image display device in the light field system to be between 1 mm and 200 mm.
