PROBLEM TO BE SOLVED: To provide a light emitting device suppressing leakage current between adjacent pixels without using an insulating film partitioning between pixels and achieving higher definition.SOLUTION: A groove along one side of a first electrode 2 is formed in an insulating layer 1 to reduce the film thickness of a first charge transport layer 3, thereby suppressing leakage current between adjacent pixels. |
