  • Publication number: 20200286923
    Abstract: This array antenna 10 comprises a plurality of antenna units 11. This array antenna 10 is provided with a patch substrate 12, a slotted substrate 13 and a liquid crystal layer 14. At least one of the patch substrate 12 and the slotted substrate 13 is provided with a liquid crystal alignment film 22, 23 on the liquid crystal layer 14 side. The liquid crystal alignment film 22, 23 is formed using a polymer composition that contains a compound (M) which has at least one structure selected from the group consisting of partial structures represented by formula (1) and nitrogen-containing heterocyclic rings (in formula (1), R1 represents a hydrogen atom or a monovalent organic group having 1-10 carbon atoms; and each of R2 and R3 independently represents a divalent organic group, provided that the R2 and R3 moieties are not aromatic ring groups at the same time).

  • Publication number: 20140226116
    Abstract: A liquid crystal display includes a liquid crystal layer and a liquid crystal alignment film. The liquid crystal layer includes a liquid crystal composition that includes a cyclohexane compound represented by a formula (1). The liquid crystal alignment film is provided using a liquid crystal aligning agent that includes a polymer which is a polyamic acid, a polyimide, a polyamic ester, or a combination thereof. R11 and R12 are each independently a monovalent chain hydrocarbon group, or a group obtained by substituting —CH2— included in the chain hydrocarbon group with —O—, —CO—, or —COO—. At least one hydrogen atom included in R11 and R12 is optionally substituted with a halogen atom or a cyano group. Q1 is a divalent group represented by a formula (1-1), a divalent group represented by a formula (1-2), or a divalent group represented by a formula (1-3).
