PURPOSE: To increase the brightness of a reproduced image and to prevent a black stripe in an observation area from generating while suppressing the complexity of a device in a three-dimensional display device. CONSTITUTION: This device is equipped with a transmission type image display panel 11 provided with an opening part in accordance with a picture element and which displays an image, a first lenticular lens 7 arranged on the light incident surface of the image display panel, and a second lenticular lens 8 arranged on the light emitting surface of the image display panel. The first lenticular lens 7 is formed in such a way that the arranging pitch of its cylindrical lens is set equal to the picture element pitch of the image display panel, and almost incident parallel rays are converged at every opening part, and the second lenticular lens 8 in such a way that the arranging pitch of its cylindrical lens is set larger than the picture element pitch of the image display panel. |
