Abstract

Water running on a flat cable ( 66 ), which connects together a control circuit board ( 56 ) provided on a rear surface of a liquid crystal module ( 52 ) and a source driver board ( 60 ) arranged on a lower surface of the liquid crystal module, is prevented from entering the source driver board ( 60 ). A source driver board ( 60 ) is arranged on a lower surface of a mold frame ( 62 ) supporting a lower edge of a liquid crystal module ( 52 ). A flat cable ( 66 ) passes through a gap between a board cover ( 58 ) and a rear end surface ( 114 ) of the mold frame ( 62 ). A water absorbing member ( 110 ) adhered to the rear end surface ( 114 ) is applied to the flat cable ( 66 ).

Claims (5)

1. A display device, comprising: a panel-like structure comprising a display panel; a lower edge support member for supporting a lower edge of the panel-like structure; a first circuit board arranged on a rear surface of the panel-like structure; a second circuit board arranged on a lower surface of the lower edge support member; an electric cable, which passes through a rear side of the lower edge support member, for connecting the first circuit board and the second circuit board to each other; a shielding plate for covering the first circuit board, the second circuit board, and the electric cable from behind; and a water absorbing member which is sandwiched between the lower edge support member and the shielding plate together with the electric cable and is applied to the electric cable; wherein the electric cable comprises a flat cable, and the water absorbing member is adhered to a rear end surface of the lower edge support member across an entire width of a part of the rear end surface opposed to the flat cable.

2. The display device according to claim 1 , wherein the flat cable comprises a bent portion between a part extending vertically toward the first circuit board and a part extending horizontally toward the second circuit board, the bent portion comprising a groove portion recessed below a height of a connection portion with respect to the second circuit board.

3. The display device according to claim 2 , wherein the groove portion is formed across an entire width of the flat cable, and is inclined so as to be lowered toward a side edge of the flat cable.

4. The display device according to claim 1 , wherein another of the water absorbing member is adhered to the shielding plate so as to be opposed to an entire width of the flat cable.

5. The display device according to claim 1 , wherein the water absorbing member comprises non-woven fabric.
