ABSTRACT:
An EL light emitting device has: an EL light emitting layer having an EL light emitting material element; and an electrode section having a first electrode and a second electrode which are arranged on one surface side of the EL light emitting layer to be electrically separated from each other with a spacing region, and having a predetermined pattern. An alternating current electric field forming element, to form an alternating current electric field in the EL light emitting layer when an alternating current power supply voltage is applied between the first electrode and the second electrode, is adhered to the other surface side of the EL light emitting layer. A waterproof layer of a synthetic resin is arranged between at least one of the first electrode and the second electrode, and the EL light emitting layer.
