Abstract
Among end portions of a plurality of organic compound layers patterned by photolithography, an end portion in an area that is not located between luminescent elements and that is located in an area covered with a second electrode is formed to have a smaller inclination angle than that of an end portion located between the luminescent elements.
Claims13
An organic electroluminescent (EL) device, comprising:
- a plurality of organic EL elements, each including a first electrode, an organic compound layer including at least a luminescent layer, and a second electrode which are stacked in this order in a predetermined area on a substrate;
- and
- a wiring including an external connection terminal arranged outside the predetermined area on the substrate and a contact portion electrically connected to the external connection terminal,
- wherein the first electrode is divided per the organic EL element,
- wherein the organic compound layer is divided per one or a plurality of the organic EL elements, and
- wherein the second electrode is commonly provided to the plurality of organic EL elements, and electrically connected to the wiring via the contact portion, and
- wherein, among end portions of the organic compound layers, an end portion of an organic compound layer that is not located between organic EL elements and that is located in an area where the second electrode is provided has a smaller inclination angle with respect to the substrate than that of an end portion of an organic compound layer located between the organic EL elements.
