A switchable two and three dimensional display (2D/3D display) suitable for being viewed by a user is provided. The 2D/3D display includes a liquid crystal display (LCD) panel and a switchable barrier. The LCD panel has a display area, a non-display area surrounding the display area, and a first black matrix extending from the display area to the non-display area. The first black matrix has a number of openings arranged in array and merely distributed within the display area. The switchable barrier has a 3D image control area, a non-display area surrounding the 3D image control area, and a second black matrix merely disposed within the non-display area. The second black matrix surrounds the 3D image control area. An area occupied by the 3D image control area is different from an area occupied by the display area.
