<p>Lamp units (20a-20d) having cold cathode tubes (straight tube lamps)(21, 22) and inverter circuits (drive circuits)(24) for lighting and driving the cold cathode tubes (21, 22) are arranged in a direction orthogonal to the longitudinal direction of the cold cathode tubes (21, 22). Further, the inverter circuits (24) of the lamp units (20a-20d) are arranged distributed at both one end side and the other end side in the longitudinal direction of the cold cathode tubes (21, 22). By this, brightness at light emission surfaces of the cold cathode tubes (21, 22) is uniformized even if they are long.</p> |
