A display device has a first electrode provided corresponding to each of a plurality of pixels in a region in which the plurality of pixels is provided, a second electrode provided over the plurality of pixels and extending to a contact region provided outside the pixel region, a light emitting layer provided between the first electrode and the second electrode, a third electrode provided in the contact region, an organic insulating layer covering the third electrode and provided with a contact hole exposing the third electrode, and a connection portion between the second electrode and the third electrode in the contact hole, wherein the maximum distance between any two points on the outer periphery of the connection portion is 1 μm or more and 100 μm or less.

First claim

Opening claim text (preview).

What is claimed is: 1. A display device comprising: a first electrode provided corresponding to each of a plurality of pixels in a pixel region in which the plurality of pixels is provided; a second electrode provided over the plurality of pixels and extending to a contact region adjacent to the pixel region in a peripheral region provided surrounding the pixel region; a light emitting layer provided between the first electrode and the second electrode; a third electrode provided in the contact region and electrically connected to the second electrode; and a plurality of island-shaped organic layers provided in the contact region, wherein at least one of the plurality of island-shaped organic layers overlaps with a circular region which completely overlaps with the contact region, and a radius of the circular region is 1 μm or more and 100 μm or less. 2. The display device according to claim 1 , wherein the second electrode includes a MgAg alloy. 3. The display device according to claim 1 , wherein the third electrode is connected to the second electrode in the contact region via an opening provided between a plurality of island-shaped organic layers adjacent to each other. 4. The display device according to claim 1 , wherein the light emitting layer includes an organic electroluminescent material.
