7. The display device of claim 6 , wherein a width of the hole of the second frame in a first direction is smaller than a width of the hole of the second frame in a second direction.

8. The display device of claim 6 , wherein the chassis fixing member comprises a screw and a spiral shaped guiding groove is formed on at least one of the holes of the second frame, the second plate and the sidewall.

9. The display device of claim 1 , further comprising a first frame fixing member fixing the first frame to the top chassis.

10. The display device of claim 9 , wherein the second plate of the top chassis includes a second plate hole that has a shape that corresponds to a shape of the first frame fixing member.

11. The display device of claim 9 , wherein the first frame fixing member comprises a screw and a spiral shaped guiding groove is formed on at least one of the holes of the second plate and the first frame.

12. The display device of claim 1 , wherein a cross section of the first frame comprises a shape of a ‘T’.

13. The display device of claim 1 , wherein the first surface of the first frame contacts the inner surface of the first plate and the second surface contacts the inner surface of the second plate.

14. A method for producing a display device, comprising the steps of:

disposing a lens plate on a first frame;

fixing the first frame with the lens plate to a top chassis to form a top chassis unit; and

fixing the top chassis unit to a backlight unit having a display panel disposed thereon, a peripheral area of the display panel disposed in a recess portion of the first frame, wherein the first frame includes a first frame hole having an opening surrounded on three sides by the first frame, the hole positioned in a middle portion of the first frame adjacent and extending parallel to a supporting portion of the first frame extended between the lens plate and the display panel.

15. The method for producing the display device according to claim 14 , further comprising:

fixing the first frame to the top chassis by a first frame fixing member inserted into the first frame hole.

16. The method for producing the display device according to claim 14 , further comprising:

fixing the top chassis unit to the backlight unit by a chassis fixing member.

17. A display device comprising:

a display panel;

a first frame including an opening and covering a peripheral area of the display panel;

a lens plate disposed on the first frame;

a backlight unit supporting a peripheral area of the display panel and providing light; and

a top chassis covering a peripheral area of the lens plate and coupled to the backlight unit,

wherein, the backlight unit comprises:

a light source generating light;

a light guiding member guiding the light to the display panel;

a bottom chassis receiving the light source and the light guiding member, the bottom chassis including a base plate and a sidewall extended from the base plate; and

a second frame positioned between the light guiding member and the display panel and covering a peripheral area of the light guiding member and supporting a peripheral area of the display panel, wherein the second frame contacts an outer surface of the sidewall, wherein a top side of the second frame adjacent the display panel contacts a bottom side of the first frame, wherein the bottom side of the first frame is parallel to a top surface of the light guiding member,

wherein the top chassis comprises:

a first plate facing an upper surface of the first frame; and

a second plate facing a side surface of the first frame.

18. The display device of claim 17 , further comprising:

a chassis fixing member fixing the top chassis to the backlight unit.

19. The display device of claim 18 , wherein the second frame comprises a portion disposed between the second plate and the sidewall of the bottom chassis and the second frame, the second plate and the sidewall each has a hole having a shape that corresponds to a shape of the chassis fixing member.

20. The display device of claim 17 , further comprising a first frame fixing member fixing the first frame to the top chassis.
