摘要
A liquid crystal display apparatus includes a backlight assembly which includes a device for driving the backlight including a light emitting diode (“LED”) used as a light source, which has a high efficiency and a high reliability for controlling brightness of each color light. The driving device drives a first, second and third LED unit emitting a first, second and third light, respectively. The driving device includes a first driving part emitting the first light in response to a brightness control signal and outputting a reference control signal in response to a first brightness of the first light, a second driving part driving the second LED units generating the second light of which second brightness is controlled in response to the reference control signal, and a third driving part driving the third LED units generating the third light of which third brightness is controlled in response to the reference control signal.
