Abstract
The present invention provides a novel organic EL panel adapted to be color tunable by a user, for example. An organic EL panelof the present invention includes: a first substratea second substratean organic EL elementand a sealing layer. One surface of the first substrateis a mounting surface on which the organic EL elementis disposed. The first substrateand the second substrateare laminated in such a manner that the mounting surface of the first substrateand one surface of the second substrateface each other with the sealing layerinterposed therebetween. The sealing layerseals a gap between the first substrateand the second substratealong an entire periphery of a region where the first substrateand the second substrateface each other. The first substrateincludes a light incident sectionon which laser light is incident and a light guide sectionthat directs the incident laser light in an in-plane direction.
