ABSTRACT:
A backlight unit of a liquid crystal display includes a lamp, a balancing pattern capacitor electrically connected to the lamp for current balance, a transformer electrically connected to the lamp via the balancing pattern capacitor, a sensing pattern capacitor electrically connected to a terminal of the balancing pattern capacitor connected to the lamp to detect an abnormal driving state of the lamp, and a feedback circuit unit electrically connected to the sensing pattern capacitor to control the abnormal driving state of the lamp. A liquid crystal display device including the backlight unit is also disclosed.
