Method for manufacturing organic EL device and organic EL device

摘要

Provided is a method for manufacturing an organic EL device which suppresses a deterioration in the light emission properties. In this method, while first and second electrode layers are prevented from being in contact with each other, an organic layer is allowed to protrude from the first electrode layer toward at least both outer sides in the longitudinal direction of a substrate. Further, the second electrode layer is allowed to protrude from the organic layer toward at least both outer sides in the longitudinal direction. Thereby, the first electrode layer, the organic layer, and the second electrode layer are formed so that both end edges of the organic layer in a longitudinal direction of the substrate are covered by both end sides of the second electrode layer in the longitudinal direction, on at least both outer sides of the light emitting part in the longitudinal direction.

1. A method for manufacturing an organic EL device, comprising:
sequentially forming an insulating layer, a first electrode layer, an organic layer having at least a light emitting layer as an organic constituent layer, a second electrode layer, and a sealing layer, on one surface of a strip-shaped metal substrate; and thereby manufacturing the organic EL device having a portion in which the first electrode layer, the organic layer, and the second electrode layer overlap and which serves as a light emitting part, wherein while the first electrode layer and the second electrode layer are prevented from being in contact with each other, the first electrode layer, the organic layer, and the second electrode layer are formed so that both end edges of the organic layer in a longitudinal direction of the substrate are covered by both end sides of the second electrode layer in the longitudinal direction, on at least both outer sides of the light emitting part in the longitudinal direction of the substrate, by allowing the organic layer to protrude from the first electrode layer toward at least both outer sides of the substrate in the longitudinal direction and further allowing the second electrode layer to protrude from the organic layer toward at least both outer sides of the substrate in the longitudinal direction.
