Abstract
In a backlight device, lamp units including cold cathode-ray tubes (straight-tube lamp portions) and inverter circuits (driving circuits) for driving to switch on the cold cathode-ray tubes are arranged along a direction that is substantial perpendicular to a longitudinal direction of the cold cathode-ray tubes. Further, the inverter circuits of the lamp units are disposed separately on one end portion side and other end portion side in the longitudinal direction of the cold cathode-ray tubes. Thereby, even when using the longitudinal cold cathode-ray tubes, brightness on a light emitting surface can be made uniform.
