Backlight assembly, display module having the backlight assembly and method of manufacturing receiving container receiving the backlight assembly

A backlight assembly, a display module having the backlight assembly, and a method of manufacturing a container of receiving the backlight assembly are provided to overlap side walls and extension parts of a bottom chassis around corners of the bottom chassis, to pass combining parts through combining holes, and to combine the side walls with corners for manufacturing a slim backlight assembly and maintaining torsion strength. A backlight assembly comprises a light source unit, a mold frame, and a bottom chassis(130). The mold frame receives the light source unit. The bottom chassis includes a bottom plate(150), side walls(141,142,143,144) extending from the bottom plate, and extension parts(161,162,163,164) which are curved from the side walls and overlapped by neighboring walls. The mold frame and the bottom chassis are integrated. Combining holes(171,172,173,174) are formed at the extension parts. Combining parts are at sides of the mold frame.
