ABSTRACT:
A panel light source includes: a planar light transmissive electrode formed by ITO film, which is 0.1 μm thick and 430 mm×430 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 μm wide, 430 mm long, and 3 μm thick. The specific resistance of aluminum is 2.7×10−6Ω, and the resistance between first and second ends of the linear electrodes is 80 Ω. The specific resistance of ITO is 4×10−4Ω, and the resistance between a first and second end of the light transmissive electrode is 40 Ω. 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.
