  • Publication number: 20240040911
    Abstract: Provided is a display device capable of suppressing reflection of light of a visible light region in a peripheral region. The display device includes a reflecting portion, an insulating layer, an electrode, and a filter of a predetermined color that are provided in this order in a region around a display region. The reflecting portion and the electrode constitute a resonator structure, which weakens light of the predetermined color.

  • Publication number: 20230276682
    Abstract: A light emitting element includes: a light emitting unit (30); an intermediate layer (40) covering the light emitting unit (30); an optical path control unit (70) disposed on a part of the intermediate layer (40) and having positive optical power; and a covering layer (71) covering an outer region (70A) of the intermediate layer (70) surrounding a part (70B) of the intermediate layer (70) on which the optical path control unit (70) is formed and the optical path control unit (70), and satisfies n0?n1>n2, in which n0 represents a refractive index of a material constituting a part (41) of the intermediate layer (40) in contact with the optical path control unit (70), n1 represents a refractive index of a material constituting the optical path control unit (70), and n2 represents a refractive index of a material constituting the covering layer (71).

  • Publication number: 20230221469
    Abstract: A light-emitting element (10) includes: a light-emitting part (30) including a light-emitting region; a first optical path control unit (71) which has positive optical power and to which light emitted from the light-emitting region enters; a second optical path control unit (72) which has positive optical power and to which light exited from the first optical path control unit (71) enters; and a bonding member (35) interposed between the first optical path control unit (71) and the second optical path control unit (72), in which an optical axis (LN1) of the first optical path control unit (71) is displaced from an optical axis (LN2) of the second optical path control unit (72).
