A backlight assembly for a display includes a microwave generating member, a light-generating member and a light-guiding member. The microwave generating member generates a microwave and light-generating member generates light by using the microwave. Light-guiding member is connected to light-generating member to guide light generated from light-generating member. The backlight assembly generates light by using a microwave instead of an electrode and a fluorescent material so that the display device may have enhanced luminance uniformity and stability.
