A multipurpose advertisement board comprising: a window; a vertical film comprising multiple film strips connected in series; a first image expression device comprising an operating unit rotatably connected to a vertical winding roller in upper and lower portions of the frame that vertically move the vertical film to display the multiple film strips in order; a horizontal film comprising multiple film strips connected in series; a second image expression device installed on the window frame, wherein the second image expression device comprises an operation unit rotatably connected to a horizontal winding roller installed in left and right portions of the window frame to rotate or release the horizontal film, thereby horizontally moving the horizontal film so that the multiple film strips of the horizontal film overlap with the film strips of the vertical film to make a combined image.

A display device includes a base holder having a cavity and a roller assembly. The roller assembly can include an upper cylindrical roller, a lower cylindrical roller, a framework arranged and constructed to maintain the upper cylindrical roller and the lower cylindrical roller a predetermined distance away from each other, and a conveyor belt wrapped around the upper cylindrical roller and the lower cylindrical roller. At least one or more rotating mechanisms can be attached to one or more of a left side of the upper cylindrical roller, a right side of the upper cylindrical roller, a left side of the lower cylindrical roller, or a right side of the lower cylindrical roller, where the one or more rotating mechanisms drive the lower cylinder to rotate and cause the conveyer belt to move around the upper cylinder and the lower cylinder.
