Abstract

A display device of the invention is provided with: a display panel; a lower frame that covers the lower side of the display panel, and includes a front wall and a bottom wall; a drain hole formed to the bottom wall; and a water-absorbing porous member provided to the inner surface of the bottom wall in such a manner as to cover the drain hole. With such a configuration, the resulting display device can swiftly drain any liquid entering inside thereof.

Claims (35)

1. A display device, comprising:

a display panel;

a lower frame that covers a lower side of the display panel, and includes a front wall and a bottom wall;

a drain hole formed to the bottom wall; and

a water-absorbing porous member provided to an inner surface of the bottom wall to cover the drain hole,

wherein on a rear side of the drain hole formed to the inner surface of the bottom wall, a weir member is provided to extend in a lateral direction for defining a flow path.

2. The display device according to claim 1 , wherein

the porous member is higher in affinity than the inner surface of the bottom wall.

3. The display device according to claim 1 , wherein

the porous member is provided plurally, and the porous members are disposed to be spaced from one another.

4. The display device according to claim 1 , wherein

a front surface of the lower side of the display panel is provided with a flow-path change member.

5. The display device according to claim 4 , wherein

the flow-path change member is lower in affinity than an inner surface of the front wall.

6. The display device according to claim 4 , wherein

a bottom surface of the flow-path change member is at least provided with a slanted surface that is slanted upward from a front to rear side.

7. The display device according to claim 4 , wherein

a bottom surface of the flow-path change member is formed with a concave portion.

8. The display device according to claim 4 , wherein

a space is formed between the flow-path change member and an inner surface of the front wall.

9. The display device according to claim 4 , wherein

the flow-path change member is a cushioning member having the elasticity.

10. The display device according to claim 1 , further comprising:

a vertical wall opposing the display panel and a horizontal wall opposing the bottom wall on a rear side of the display panel; and

a lower support frame disposed to the vertical wall with a plurality of support projections for supporting the display panel.

11. The display device according to claim 10 , wherein

a lower surface of the horizontal wall is formed with a convex guide portion where a space between an upper surface of the bottom wall and the lower surface of the horizontal wall is narrower than any remaining portions.

12. The display device according to claim 11 , wherein

the convex guide portion extends from a front to rear side.

13. The display device according to claim 12 , wherein

the convex guide portion extends to the rear side from a rear end of the bottom wall, and protrudes downward.

14. The display device according to claim 10 , wherein

the support projections are each formed with a concave portion opening upward.

15. The display device according to claim 14 , wherein

a bottom surface of the concave portion formed to each of the support projections is formed with a notch or a hole.
