  • Patent number: 11797141
    Abstract: A touch sensor member precursor includes touch sensor pattern portions, lead wires led out from the touch sensor pattern portions, connection terminals connected to the lead wires, connection wirings connected to the connection terminals, and a potential difference elimination pattern portion connected to the connection wirings. The touch sensor pattern portions, the lead wires, the connection terminals, the connection wirings, and the potential difference elimination pattern portion are disposed on the same surface of a substrate, each of the connection wirings has a connection wiring width Wd, the connection terminals adjacent to each other are spaced from each other by a distance Sc between closest terminals at positions closest to each other, and a relationship of Wd<Sc is satisfied.

  • Patent number: 11744144
    Abstract: An organic electroluminescent element including a luminescent compound represented by the following formula (in which R1 to R14 each independently represent a hydrogen atom, a deuterium atom, an alkyl group, an aryl group, a heteroaryl group, a fluorine atom, a cyano group, an amino group, an alkoxy group, an aryloxy group, a thio group, or a silyl group, and 8 to 13 groups out of R1 to R14 each represent a hydrogen atom or a deuterium atom) in a light emitting layer has high durability and excellent chromaticity.

  • Publication number: 20230089629
    Abstract: Provided is an antenna where low transmission loss and visibility are simultaneously achieved. The antenna includes: a transparent film substrate; an antenna element that is provided on one surface among two surfaces of the transparent film substrate; and a ground part that is provided on the other surface among the two surfaces of the transparent film substrate. The antenna element and the ground part are formed of a mesh pattern formed of a fine silver wire, and a line width of the fine wire is 1.0 ?m or more and less than 5.0 ?m. A thickness of the transparent film substrate is 30 ?m or more and 300 ?m or less.

  • Patent number: 11563178
    Abstract: The disclosure relates to organic electroluminescent elements, compounds for use in the elements, and devices using the elements, which include a compound represented by the following General Formula (1): where R1 to R3 and R6 to R8 each independently represents a hydrogen atom, which may be a deuterium atom, or a substituent with a Hammett substituent constant ?p value of ?0.15 or more, R5, R9 and R10 each independently represents a hydrogen atom or a substituent, L1 represents a divalent linking group, DG1 represents a donor group, and n1 represents 1 or 2, and where R1 to R3, R5 to R10, L1, and DG1 are not bound to each other to form a ring.
