Abstract: Provided is a three-dimensional (3D) image display apparatus using laser beam scanning (LBS) projection optical systems. The 3D image display apparatus includes a plurality of LBS projection optical systems arrayed in horizontal and vertical directions, an input unit through which a 3D image signal is input, and an image signal controller configured to distribute the 3D image signal input through the input unit to the LBS projection optical systems. Each of the arrayed LBS projection optical systems has a beam-projection center point for outputting light to an outside of the LBS projection optical system, and an image projected from the beam-projection center point is a horizontal-parallax image based on the beam-projection center point.
