4 to 7 are cross-sectional views illustrating an assembly process of a display device having a waterproof member according to an embodiment of the present invention.

Referring to FIG. 4, the first bending part 133 constituting the first extension part 130 of the waterproof member 100 is vertically bent. And the display panel 200 is inserted between the head part 110 of the waterproof member 100 and the first bending part 133. The first sealing rib 132 and the head side sealing rib 120 are in contact with the rear surface and the front surface of the panel 200 to support the display panel 200, .

5 to 6, the backlight unit 300 is disposed on the rear surface of the display panel 200. FIG. Then, the front edge portion of the backlight is closely adhered to the back surface of the first bending part 133. In this state, the second bending part 143 of the second extension part 140 is vertically bent with respect to the second groove part 144. Then, the inner cover 400 is inserted between the backlight unit 300 and the second bending part 143. It is of course possible to position the inner cover 400 on the back surface of the backlight unit 300 and then bend the second bending part 143.

Referring to FIG. 7, the outer cover 500 is assembled with the edge of the inner cover 400 inserted between the backlight unit 300 and the second bending part 143.

In detail, the front surface of the outer cover 500 is opened. Therefore, the front cover of the outer cover 500 is assembled so as to be in close contact with the outer rear surface of the head 110 constituting the waterproof member 100. In this state, the screw 600 is sequentially inserted through the outer cover 500, the second bending part 143 of the second extension part 140, and the edge of the inner cover 400 , And combine them into one body.

Meanwhile, the material of the waterproof member 100 may be rubber. If the hardness of the member fixed to the display panel 200 is high, a light splitting phenomenon may occur. Why?

However, when the waterproof member () of the rubber material is applied as shown in the present invention, the light leakage phenomenon can be prevented. In detail, since the waterproof member 1 made of rubber has ductility, it is tightly adhered to the adhered object, that is, the shape of the display panel, while being deformed. As a result, since the degree of adhesion is higher than that of the hard waterproof member, the light leakage through the gap can be prevented.

In addition, since the degree of adhesion of the waterproof member is improved, the waterproof ability is improved. Further, since the groove portion 144 can be easily bent on the basis of the groove portion 144, assemblability can be improved.

Further, the waterproof member may be made of rubber having different hardness at each position, thereby enhancing the reliability of the product. For example, the head portion 110 is made of a rubber material having a high hardness, and the first sealing rib 132 and the second sealing rib 120 supporting the panel 200 are made of a rubber material having a relatively low hardness It can also be produced.
