A backlight assembly includes a plurality of unit blocks to emit light. Each unit block includes a light-emitting part and a driving part. The light-emitting part includes at least two red light-emitting diodes (LEDs), two green LEDs, and two blue LEDs. The driving part includes a red LED-driving element that provides the red LEDs with a driving voltage, a green LED-driving element that provides the green LEDs with a driving voltage, and a blue LED-driving element that provides the blue LEDs with a driving voltage. LEDs may be driven together in a group, or may be driven individually to sequentially emit red light, green light, and blue light so a color filter is not included in a display panel having the backlight assembly. A driving element is connected to the LEDs to reduce manufacturing costs for the driving element circuits, thereby reducing manufacturing costs of the backlight assembly.
