Further, the panel 7000 can be supported by seating the panel 7000 on the upper surface 5110 of the panel seating sheet fixing part 5000.

The fixing protrusion 8400 can prevent the optical member 4000 from moving in the X and Y directions as well as in the Z direction by fixing the optical member 4000 and the panel seating sheet fixing unit 5000.

The sheet fastening portion 2130, the panel seating sheet fixing portion 5000 and the fixing protrusion 8400 can not only fix the optical member 4000 and the panel 7000, but also can be combined organically with each other, .

In addition, the panel seating sheet fixing part 5000 can prevent leakage of light due to light by blocking the leakage of light to the side surface and the upper edge area of the optical member 4000, The power consumption can be reduced.

Also, by replacing the functions of the conventional guide panel using the shape of the bottom cover 1000, the panel seating sheet fixing part 5000 and the fixing protrusion 8400, cost reduction and simplification of the manufacturing process can be achieved can do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
