  • Publication number: 20230086115
    Abstract: A light emitting device includes a light emitting region constituted by light emitting elements arranged in a matrix, in which optical elements are included as optical elements formed in such a way as to correspond to the light emitting elements and configured to adjust a direction of emanating light, the optical elements being formed in such a way that one of a color filter layer and a transparent layer is formed to constitute a lower layer portion on an incident side and another is formed to constitute an upper layer portion on an emanating side, and the upper layer portion and at least a part of the lower layer portion are formed to be exposed to an interface with an outside.

  • Patent number: 11532680
    Abstract: A light emitting element 10 includes a base body 26, a first electrode 31 formed on the base body 26, an organic layer 33 formed on the first electrode 31 and having at least a light emitting layer, and a second electrode 32 formed on the organic layer 33. The second electrode 32 has at least two edge portions 32A and 32B opposed to each other, and each of the edge portions 32A and 32B of the second electrode 32 protrudes from an end face 33? of the organic layer 33.

  • Patent number: 10559636
    Abstract: The display device including a pixel circuit has a first line, a transistor, a light emitting element, and a second line. The transistor is located between the second line and an electrode of the light emitting element. Either the first line or the second line is wired in a region that overlaps a light emitting region of the light emitting element in a lamination direction of layers. The second line intersects the first line outside of the light emitting region and overlaps a non-light emitting region of the light emitting element.
