Kind Code:
A1
Abstract:
Provided is a long-life organic EL illumination panel which is flexible and, even when a load is applied by bending, impact or vibration, can suppress the occurrence of defects in an electrode layer and an organic layer containing an organic EL material, and which can suppress the occurrence of dark spots due to short circuiting. This organic electroluminescent illumination panel comprises: a pair of electrode layers, at least one of which is transparent, between a flexible film substrate and a flexible sealing material, at least one of which is transparent; and an organic layer containing an organic electroluminescent material which is sandwiched between said pair of electrode layers. This organic electroluminescent illumination panel has multiple spacers which are disposed on one of the electrode layers laminated on the flexible film substrate and which are provided so as to pass through the organic layer and the other electrode layer.
