SPATIAL IMAGE DISPLAY DEVICE

摘要

Disclosed is a spatial image display device capable of forming a high-definition spatial image excellent in reality.  The spatial image display device (10A) is provided with a display unit (2) having a plurality of pixels (22) and adapted for creating a two-dimensional display image corresponding to a video signal, a first lens array (1) comprising a plurality of microlenses (11) provided correspondingly to the respective pixels (22) each for focusing a light beam passing through a pixel (22), and a second lens array (3) for converting the focused light beams passing through the first lens array (1) into parallel light beams or converging light beams and outputting the resultant light beams.  The light beams passing through the respective pixels (22) of the display unit (2) are focused by the first lens array (11) and travel toward the second lens array (3).  Therefore, the light beams entering the second lens array (3) from the respective pixels (22) behave as if the light beams were the ones emitted from a point light source, and the light beams are easily converted into parallel light beams or converging light beams by the second lens array (3).
