PURPOSE:To prevent the unbalance of brightness and lighting defects by housing the lead wires of the plural light sources which are disposed on the flanks of a light transmission plate and are provided with the lead wires respectively having the lengths approximately equal to each other into housing parts in such a manner that the lead wires of the one light source do not overlap on the lead wires of the other light source. CONSTITUTION:An illuminating means 2 consists of the light transmission plate 21 and the plural light sources disposed on the flanks of the light transmission plate 21. The lead wires 221, 222 are led out of respective both ends of the linear light sources 22, such as cold cathode ray tubes and are so adjusted that the lengths from the light source ends on the terminal leading out sides of the respective light sources 22 are equal to each other. Further, a frame body 3 consisting of resin molded parts constituting an outside frame by holding and housing a light source 1 and the illuminating means 2 together with a frame 4 consisting of a metallic plate, etc., is provided with the housing parts 31 for housing the lead wires of the one light source 22 in such a manner that these lead wires do not overlap on the lead wires of the other light source 22. As a result, there is no need for considering the interference of the lead wires with each other and therefore, the impedances of the two light sources are nearly equal even if the lead wires are led out of any of the upper, lower and central lead wire leading out parts.
