A three-dimensional display apparatus comprises a display panel (display element) and a parallax barrier (optical element). The display panel displays a left-eye image and a right-eye image respectively in first subpixels and second subpixels. The parallax barrier transmits at least part of the left-eye image toward the left eye, and at least part of the right-eye image toward the right eye. A first certain number of the first subpixels and of the second subpixels are each successively arranged in each column. A region in which the first subpixels are arranged and a region in which the second subpixels are arranged are displaced from each other by a second certain number between two adjacent columns. The first certain number is greater than the second certain number and is not a multiple of the second certain number.

A method of manufacturing a stereoscopic image display device includes forming a groove by etching an edge portion of a rear surface of a lens array substrate, depositing a sticky material layer in the groove, disposed a transparent adhesive layer that differs from the sticky material layer onto a top surface of a display panel, aligning the lens array substrate and the display panel by using a camera, and joining the display panel and the lens array substrate by using the transparent adhesive layer.

An image display device includes a display panel displaying an image, and a diffractive element formed to operate in a 2D mode or a 3D mode so that the image of the display panel is perceived as a 2D image or a 3D image after passing through the diffractive element.

A three-dimensional (3D) display module and a 3D display device are disclosed. The 3D display module has a first assembly and second lens assemblies respectively having multiple first and second lenses arranged in parallel. The extending directions of the first and second lens assemblies intersect to form a specific angle and the refractive indexes of the first and second cylinder lenses are different. A liquid crystal layer is formed between the first and second cylinder lens assemblies. A first and second electrode layer are respectively formed on two sides of the liquid crystal layer. By a control technique of arranging the cylinder lens and the liquid crystals in a specific angle, a lateral and perpendicular autostereoscopic 3D display effect is accomplished. The 3D display module has advantages of a simple manufacturing and an advantage of thinning since a period and a focal length of the cylinder lens are smaller.

A multi-view display device is provided, and the multi-view display device at least comprises a projector, a first lens set, and a second lens set. The projector contains a scan-lamp image, and the projector slants an incident ray corresponding to the scan-lamp image with a first angle. The first lens set receives the slanted incident ray and refracts that. The second lens set is slanted with the first angle, and the second lens set receives the slanted incident ray which is refracted by the first lens set and refracts that again, so as to expand a view area of the multi-view display device.
