  • Publication number: 20190259972
    Abstract: A light emitting element, display device, and method of manufacture of the same are disclosed. In one example, a light emitting element includes a lower layer/interlayer insulation layer; a light reflection layer formed on the lower layer/interlayer insulation layer; an upper layer/interlayer insulation layer; a first electrode formed on the upper layer/interlayer insulation layer; an insulation film formed at least on a region of the upper layer/interlayer insulation layer where the first electrode is not formed; an organic layer formed over the insulation film from above the first electrode, the organic layer having a light emitting layer including an organic light emitting material; and a second electrode formed on the organic layer. A groove is formed in a portion of the upper layer/interlayer insulation layer located in an edge region of the light emitting element, and an upper portion of the groove is closed with the insulation film.
