Abstract

A flat panel display device includes a driver circuit board, a resin frame, and a metal sheet, the edge portion of which is provided with a U-shaped engagement portion to receive the resin frame. The metal sheet reinforces the resin frame and also shields electromagnetic wave noises from the driver circuit board.

Claims

1. A flat panel display device, comprising:

a display panel;

a first frame disposed on a main surface side of said display panel, said first frame having an opening corresponding to said display panel;

a second frame disposed on another surface side of said display panel, said second frame being engaged with said first frame to support said display panel; and

a circuit board provided opposite said display panel on the side of said second frame, said circuit board being electrically connected to said display panel;

said second frame including a resin frame and a metal sheet engaged with or put together with said resin frame, said metal sheet being provided to extend between said display panel and said circuit board.

2. The flat panel display device according to claim 1, wherein said metal sheet substantially covers said circuit board to electromagnetically shield the same.

3. The flat panel display device according to claim 1, wherein said second frame further includes a light source.

4. The flat panel display device according to claim 1, wherein an isolation sheet is further provided between said metal sheet and said circuit board.

5. The flat panel display device according to claim 1, wherein a flexible printed circuit board is further provided to electrically connect between said display panel and said circuit board.

6. The flat panel display device according to claim 5, wherein said display panel is a liquid crystal display panel.

7. The flat panel display device according to claim 6, wherein said display panel include a driver circuit.

8. The flat panel display device according to claim 7, wherein said display panel includes a circuit array substrate and a counter substrate provided opposite to said array substrate and said driver circuit is integrated in said array substrate.

9. The flat panel display device according to claim 1, further comprising a light guide plate.
