PROBLEM TO BE SOLVED: To provide an inexpensive two-dimensional image transmitting device for assembling a minute lens array in front of an image display device having a planar image display surface such as a liquid crystal display device, etc., making an image position coincident with the front of the image display device frame body by spatial image formation and preventing a parallax from causing. SOLUTION: This device is provided with an erect unmagnification optical system consisting of the minute lens arrays 3 arranging plural mixture lens bodies 1 so that optical axes 2 of respective minute lens bodies 1 become parallel to each other and the image display device 4 having the planar image display surface. At this time, when outgoing light from the image display device 4 is made incident on the minute lens arrays 3, an incident angle is limited within a fixed angle for the optical axes 2 of the minute lens bodies 1. |
