发明名称 LIGHT EMITTING PANEL AND LIGHT EMITTING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a technology capable of suppressing reduction in the luminance attended with changes over time with a simple configuration, and extending an apparent lifetime in the case of applying constant driving to a light emitting panel whose light emitter is configured with an organic EL element. SOLUTION: A light emitting device 10 disclosed herein includes a light emitting panel 11, a constant current source 12 for supplying a constant current to the light emitting panel 11, and a switch SW for switching the light emitting panel 11 into a light emitting state or a non light emitting state. The light emitting panel 11 includes the organic EL element 14, and a shunt 15 located in parallel with each other on a substrate 13. An organic light emitter is provided between first electrode and second electrode 18 of the organic EL element 14. The first electrode is configured with a transparent electrode, and the shunt 15 is located on the transparent electrode at a position closer to a terminal 28 of the transparent electrode that the organic EL element 14. An amount of a current flowing through the shunt 15 is decreased as attended with a lapse of a light emitting time of the organic light emitter. COPYRIGHT: (C)2007,JPO&INPIT
