PURPOSE: A display for both 2D and 3D is provided to selectively realize 2D(two-dimension) and 3D(three-dimension) in a single display by using a pin hole, thereby utilizing 2D and 3D in fields requiring importance of image data. CONSTITUTION: An image forming display(31) receives an image signal for outputting an image. A pin hole array part includes a first transparent substrate, lower electrode lines formed on the first transparent substrate, a liquid crystal layer(34) on the lower electrode lines to transmit a beam emitted from the image forming display, upper electrode lines formed on the liquid crystal layer and formed vertical to the lower electrode lines, and a second transparent substrate(36) formed on the upper electrode lines. The liquid crystal layer selectively forms a pin hole area according to application of external power source.
