ORGANIC ELECTROLUMINESCENT DISPLAY DEVICE

摘要

An organic electroluminescent display device includes a first insulating layer that buries a peripheral portion of a first electrode and has an opening exposing an area of the first electrode inner to the peripheral portion thereof; a second electrode that is in contact with the first electrode in the opening and is provided continuously on a top surface of the first electrode and onto a top surface of the first insulating layer; a second insulating layer covering a peripheral portion of the second electrode; an organic EL layer; and a third electrode. The second electrode includes a stepped portion. An area where the stepped portion is included and the second electrode, the organic electroluminescence layer and the third electrode overlap each other is a light emitting area. Light emitted by the organic EL layer is reflected by the stepped portion.

1. An organic electroluminescent display device, comprising:
a first electrode connecting to a light emitting control device; a first insulating layer covering a peripheral portion of the first electrode and having an opening exposing an area of inner side of the peripheral portion of the first electrode; a second electrode contacting the first electrode in the opening of the first insulating layer and from the upper surface of the first electrode to the upper surface of the first insulating layer; a second insulating layer covering a peripheral portion of the second electrode; an organic electroluminescence layer extending from a top surface of the second electrode to a top surface of the second insulating layer; a third electrode over the organic electroluminescence layer; the second electrode including a stepped portion between the first electrode and the first insulating layer; and an overlapping area of the second electrode, the organic electroluminescence layer and the third electrode each other is a light emitting area, and the light emitting area is including the stepped portion.
