Patent ID: 7817223

Claim:
A liquid crystal display device comprising: a liquid crystal panel which interposes liquid crystal between a first panel substrate having thin film transistors and a second panel substrate having color filters; and a backlight unit which supplies light to the liquid crystal panel, wherein the backlight unit includes a plurality of cold cathode fluorescent lamps which extends toward a second side portion from a first side portion; the cold cathode fluorescent lamps include a first cold cathode fluorescent lamp and a second cold cathode fluorescent lamp; the first cold cathode fluorescent lamp connects an electrode formed on a first side portion thereof to an inverter circuit on a first printed circuit board and connects an electrode formed on a second side portion thereof to a ground; the second cold cathode fluorescent lamp connects an electrode formed on a second side portion thereof to an inverter circuit on a second printed circuit board and connects an electrode formed on a first side portion thereof to a ground, and the inverter circuits formed on the first printed circuit board are configured such that the respective neighboring inverter circuits supply AC voltages having phases opposite to each other.
