ABSTRACT:
An EL device is disclosed which comprises a transparent electrode provided directly on a moistureproofing member made of a light-transmitting sheet member, a light-emitting layer provided on the transparent electrode for emitting light, a back electrode provided on the light-emitting layer, and a protection member provided on the outside of the back electrode and bonded with the moistureproofing member at the circumference of the light-emitting layer, weighs considerably lighter than an EL device employing a glass substrate, and has a higher luminous characteristic as compared with a similar EL device employing light-transmitting sheet members. Since, the EL device employs fewer number of the expensive light-transmitting sheet members than the mentioned similar EL devices, it can be manufactured at lower cost and through simpler manufacturing processes.
