Patent number: 11428993Abstract: It is a method for manufacturing a liquid crystal display device in which an anchoring force causing liquid crystal molecules to be vertically aligned can be exerted sufficiently. A liquid crystal display device (1) including two substrates AM and CF and a liquid crystal layer (4) sandwiched therebetween can be manufactured. The liquid crystal display device manufacturing method includes: a first step of subjecting a surface of one of the substrates AM and CM that is to be in contact with the liquid crystal layer (4) to hydrophilization treatment; and a second step of disposing the two substrates AM and CF so as to face each other such that the two substrates are in contact with a liquid crystal composition containing liquid crystal molecules and an alignment aid having a polar group and having the function of causing the liquid crystal molecules to be aligned spontaneously.Type: GrantFiled: June 20, 2019Date of Patent: August 30, 2022Assignee: DIC CORPORATIONInventors: Ryo Kanda, Masaomi Kimura, Hyobok Cha

Patent number: 11345857Abstract: The spontaneous orientation aid for a liquid crystal composition provides storage stability and allows liquid crystal molecules to be vertically aligned without a PI layer when added to a liquid crystal composition. When used in a liquid crystal composition, the spontaneous orientation aid can adsorb to substrates sandwiching a liquid crystal composition (liquid crystal layer) and keep the liquid crystal molecules aligned in a vertical direction. The spontaneous orientation aid makes it possible to align liquid crystal molecules without a PI layer (to induce vertical alignment of liquid crystal molecules under no applied voltage and to achieve horizontal alignment of the liquid crystal molecules under an applied voltage).Type: GrantFiled: November 17, 2020Date of Patent: May 31, 2022Assignee: DIC CORPORATIONInventors: Masaomi Kimura, Yuuichi Inoue, Hidenari Akiyama, Masanao Hayashi, Tetsuo Kusumoto
