A panel light source includes: a planar light transmissive electrode formed by ITO film, which is 0.1 mum thick and 430 mmx430 mm in size; an EL layer; and a linear electrode layer formed by 4300 linear electrodes, which are arranged parallel in the Z direction. Each linear electrode is an aluminum electrode, which is 50 mum wide, 430 mm long, and 3 mum thick. The specific resistance of aluminum is 2.7x10<SUP>-6 </SUP>Omega, and the resistance between first and second ends of the linear electrodes is 80 Omega. The specific resistance of ITO is 4x10<SUP>-4 </SUP>Omega, and the resistance between a first and second end of the light transmissive electrode is 40 Omega. Negative drive voltage is applied to the first ends of the linear electrodes. Positive voltage is applied to the second end of the light transmissive electrode. Differences in voltage drops between the electrodes are reduced, compared to conventional line light sources.
