摘要：
A picture display device which displays either of two pictures having different aspect ratios on the same screen thereof includes two screening units and a filter member which is disposed ahead of the screening units. Each screening unit has a rotatable reel and a screening sheet which is wound around the reel. The screening sheet is movable by the rotation of the reel so as to fully expose a screen of the picture display device and to screen a remaining or no-signal portion of the screen.
