Backlight assembly, method of manufacturing the same and display device having the same

A back light assembly, a method of manufacturing the back light assembly and a display device having the back light assembly are provided to directly form a power supply line for transmitting power for driving point light sources in a receiving container to eliminate a printed circuit board located between the point light sources and the receiving container so as to reduce the manufacturing cost for the back light assembly and improve the cooling efficiency of the back light assembly. A back light assembly(100) includes a light generator(110) and a receiving container(130). The light generator includes at least point light source(112) for generating light and a power supply line(116) for transmitting power for driving the point light source. The receiving container receives the light generator. The power supply line is formed in the receiving container.
