Backlight assembly

A backlight assembly comprising:

• a plurality of point light sources that emit light in a first direction;
• a light source module cover comprising a printed circuit board (PCB) fixing the point light sources, an extending portion extending from the PCB and a light guide plate (“LGP”) fixing portion formed at the extending portion;
• an LGP having a light incident face disposed in adjacent to the point light sources, a side surface extending from a short side of the light incident face along the first direction, a light exit face extending from a long side of the light incident face along the first direction, and a light reflection face opposite to the light exit face to diffuse and reflect lights which incident at the light incident face;
• and
• a receiving container comprising a bottom plate supporting the light source module cover and the LGP, and a side wall formed at an edge of the bottom plate,
• wherein a fixing groove receiving the LGP fixing portion is formed at the side surface of the LGP, and the PCB is overlapped with the LGP and moves independently from the bottom plate.
