Claim:
A polymerizable liquid-crystal composition containing a polymerizable liquid-crystal compound represented by Formula (1) and an organosilicon compound having a primary amino group: wherein W is hydrogen, alkyl having 1 to 25 carbon atoms, alkenyl having 2 to 6 carbon atoms, halogen, —CN, or -(G-SP) r -P; in these alkyl and alkenyl, optional —CH 2 — may be replaced by —O—, —S—, —NH—, —N(CH 3 )—, —CO—, —COO—, —OCO—, —OCO—O—, —S—CO—, —CO—S— or —C≡C—, and optional hydrogen may be replaced by halogen; P is a polymerizable group; Sp is an alkylene having 1 to 20 carbon atoms, and in the alkylene, when the number of carbon atoms is 2 or more, optional —CH 2 — may be replaced by —O—, —CH═CH— or —C≡C—; G is a single bond, —O—, —S—, —CO—, —COO—, —OCO—, —O—COO—, —SO 2 —O—, —O—SO 2 —, —CH 2 O—, —OCH 2 —, —CF 2 O—, —OCF 2 —, —CH═CH—COO—, —OCO—CH═CH—, —C≡C—COO—, —OCO—C≡C—, —(CH 2 ) 3 O—, —O(CH 2 ) 3 —, —CH═CH—CH 2 O—, —OCH 2 —CH═CH—, —(CH 2 ) 2 —CF 2 O— or —OCF 2 —(CH 2 ) 2 —; r is 0 or 1; and MG is a mesogen skeleton represented by Formula (2): wherein T 1 and T 2 are independently 1,4-phenylene in which optional —CH═ may be replaced by —N═, 1,4-cyclohexylene in which optional —CH 2 — may be replaced by —O— or/and —S— and two carbon atoms not adjacent to each other may be crosslinked, 1,4-cyclohexenylene, naphthalene-2,6-diyl or fluorene-2,7-diyl; optional hydrogen in these rings may be replaced by halogen, —CN, —CF 3 , —CF 2 H, —NO 2 , or alkyl having 1 to 7 carbon atoms; in the alkyl having 1 to 7 carbon atoms, optional —CH 2 — may be replaced by —O—, —CH═CH— or —C≡C—, and optional hydrogen may be replaced by halogen; G 1 is a single bond, —O—, —CO—, —COO—, —OCO—, —SO 2 —O—, —O—SO 2 —, —OCF 2 —, —CF 2 O—, —CF═CF—, —CF 2 CF 2 —, —CH═CH—, —C≡C—, —CH═CH—COO—, —OCO—CH═CH—, —CH═CH—CH 2 O—, —OCH 2 —CH═CH—, —CONH—, —NHCO—, —(CH 2 ) 2 —COO—, —OCO—(CH 2 ) 2 —, —(CH 2 ) b —, —O(CH 2 ) b —, —(CH 2 ) b O—, or —O(CH 2 ) b O—; in these groups, b is an integer of 1 to 20; f is an integer of 0 to 4, and when f is 2 to 4, plural T 1 's may be the same or different and plural G 1 's may be the same or different.
