A three dimensional shade to provide a three dimensional layer structure and profile includes a movable frame and a shade. The movable frame is installed on any two sliding docks movable on a track of a upper beam. The movable frame includes at least two coupling plates that are hinged together to hang the shade. A drawing element is provided to draw and perform retraction and extension operations so that the shade can be retracted and extended to form a profile same as the movable frame to achieve the three dimensional effect.
