  • Laminate, light control device, light control member, and vehicle
    Patent number: 11163200
    Abstract: Provided is a laminate which can not only control the amount of external light transmitted, but can also be used as a mirror. A laminate 1 comprises: a first liquid crystal member 100; a reflection type polarizing member 200; and a second liquid crystal member 300. The first liquid crystal member has first liquid crystal cells with changing orientation states, and a first absorption type polarizing member.
    Type: Grant
    Filed: October 12, 2017
    Date of Patent: November 2, 2021
    Assignee: DAI NIPPON PRINTING CO., LTD.
    Inventors: Yusuke Hagiwara, Yasunori Hayashida, Tomoya Kawashima, Yukihiro Kyouden

  • Electromagnetic wave shielding material, and method for manufacturing same
    Patent number: 8395059
    Abstract: The present invention is to provide an electromagnetic wave shielding material including a transparent substrate and a convex pattern layer composed of a conductive composition formed in a prescribed pattern on the transparent substrate, wherein the conductive composition contains conductive particles and a binder resin; and in observation of a transverse cross section of the convex pattern layer by electron microscopic photography, at least a part of the conductive particles has a fused continuation and a method for manufacturing the same.

  • Electromagnetic shielding sheet, front sheet for display and electromagnetic shielding sheet manufacturing method
    Patent number: 7754981
    Abstract: A metal film 21 is laminated directly to or by means of an adhesive 13 to a transparent base sheet 11. A mesh metal film including lines defining apertures is formed by coating the metal film 21 with a mesh resist layer 109a patterned in a mesh, etching the metal film 21 through the mesh resist layer 109a, and removing the mesh resist layer 109a. The front surfaces and side surfaces of the lines of the mesh metal film are coated with a black coating layer 23.
