The N light emitting modules are disposed adjacent to the base frame such that at least a portion of the light emitting portion of the kth light guide plate (any one of k = 1 to N-1) is disposed above the light incident portion of the k + th light guide plate. Become, Each light emitting module is a display device, characterized in that the projection of each cover member is in contact with the base frame to be fixed to be spaced apart from the base frame. The method of claim 13, Each of the protrusions of the cover member is positioned such that a distance between the first protrusion and the light emitting part in contact with the base frame is smaller than the first protrusion, and includes a second protrusion formed to have a lower height than the first protrusion. Display device. The method of claim 13, wherein the base frame, At least one line portion having fastening holes for fastening cover members of the light emitting modules; And And at least one protrusion spaced apart from the line part and raised toward the light emitting part at a position corresponding to the light emitting part of the light guide plate of each light emitting module. case; A display module disposed in the case; And And a backlight unit including a base frame disposed at the rear of the display module, a plurality of light emitting modules having a fixed end fixed in front of the base frame and a free end positioned in front of the base frame. The backlight unit may include a dustproof member disposed between the free end of the light emitting module and the base frame. The method of claim 16, wherein the base frame, At least one line portion having a fastening hole for fastening the fixed ends of each of the light emitting modules; And And at least one protrusion spaced apart from the line part and raised toward the free end at a position corresponding to the free end of each light emitting module. The method of claim 16, The anti-vibration member includes a bracket mounted to the protrusion of the base frame and an elastic pad in contact with the free end of the bracket and the light emitting module, respectively. The method of claim 18, The elastic pad is a display device, characterized in that the double-sided tape. The method of claim 17, The protrusion of the base frame is inclined to have a shape corresponding to the rear surface of the free end of the light emitting module.
