Title:
有機ＥＬ発光装置
Document Type and Number:
Japanese Patent JP5803748
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an organic EL light-emitting device suitably usable in an environment having a large temperature change.SOLUTION: In an organic EL light-emitting device 100, a terminal member 30 for electric connection between an organic EL panel 10 and a wiring board 20 is formed of a folded shape with a substantially L-shaped cross section having two planes, a base end portion 31 and a protrusion portion 32. Also the terminal member 30 is designed to have the flexural rigidity of the protrusion portion 32 smaller than the flexural rigidity of the base end portion 31, so that the protrusion portion 32 of the terminal member 30 is easy to be elastically deformed than the base end portion 31. Thus, if a deformation such as a warp is produced inside the emission device (for example, on a wiring board 20), the protrusion portion 32 of the terminal member 30 is elastically deformed to absorb stress such as a warp, so as to prevent the terminal member 30 from being electrically disconnected.
