Abstract

A planar display device whose display panel main body can be easily separated from a chassis member upon disposal without preparing large equipment and a special tool. In the planar display device wherein the PDP panel main body ( 1 ) and the chassis member ( 2 ) are adhered by a two-sided tape ( 3 ), a wire ( 4 ) is previously incorporated for separating the PDP panel main body ( 1 ) from the chassis member ( 2 ) by cutting and peeling the double-sided tape.

Claims (8)

1. A planar display device having a flat panel display attached to a retention mechanism with an adhesive material, characterized in that separation means having a wire placed like teeth of a comb drawn with one stroke which divides the adhesive material into a plurality of reed-shaped blocks when viewed from a perpendicular direction with respect to the flat panel display enables separation of the flat panel display from the retention mechanism by pulling at least one end of the wire placed outside the adhesive material so as to enable sequential shearing off and peeling off of the adhesive material in blocks, folded portions of the wire being placed outside of the adhesive material, intervals of the folded portions of the wire being narrower than a width of the reed-shaped blocks, and ends of the folded portions of the wire being formed as a crossing loop.

2. A separation method of a planar display device having a flat panel display attached to a retention mechanism with an adhesive material, including the steps of:

separating the flat panel display from the retention mechanism by shearing off and peeling off the adhesive material incorporated therein in advance with a separation means;

utilizing as the separation means a wire placed like teeth of a comb drawn with one stroke so as to divide the adhesive material into a plurality of reed-shaped blocks when viewed from a perpendicular direction with respect to the flat panel display;

placing folded portions of the wire outside of the adhesive material;

forming intervals of the folded portions of the wire so as to be narrower than a width of the reed-shaped blocks;

forming ends of the folded portions of the wire as a crossing loop; and

utilizing the separation means to separate the flat panel display from the retention mechanism by pulling at least one end of the wire which is placed outside of the adhesive material so as to enable sequential shearing off and peeling off of the adhesive material in blocks.
