A backlight device ( 100 ) includes a reflection plate ( 110 ) having a reflective surface and a heat dissipating surface, and a light source module ( 120 ) disposed adjacent to the reflective surface of the reflection plate; the light source module comprising at least one cold cathode fluorescent lamp, and the cold cathode fluorescent lamp comprising at least two parallel linear portions ( 122 ) and at least one intermediate portion ( 121 ) interconnected to the at least two linear portions. The backlight device further includes a cooling module ( 130 ). The cooling module is attached on the heat dissipating surface of the reflection plate. The present backlight device can improve brightness and chroma uniformity. And the brightness of the light source module is improved, and the utilization efficiency of light thereof is also increased, accordingly.
