  • Display device, electronic device, and method of manufacturing display device with substrate including light emitting elements adhered to substrate including microlens array
    Patent number: 11769773
    Abstract: There is provided a display device including: a first substrate that is a silicon substrate and on which a plurality of light-emitting elements is formed; a second substrate including, on a surface, a color filter layer including a plurality of color filters arrayed and a microlens layer including a plurality of microlenses arrayed that are layered in this order, the microlens layer being arranged to face the plurality of light-emitting elements with respect to the first substrate; and an adhesive layer that fills a gap between the first substrate and the second substrate for bonding the first substrate and the second substrate together.

  • LIGHT-EMITTING ELEMENT AND DISPLAY DEVICE
    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).
