Abstract
A photo-alignment polymer has a repeating unit represented by Formula (1), in Formula (1), R1 represents a hydrogen atom or a substituent, X represents —O—, —S—, or —NR2—, in which R2 represents a hydrogen atom or a substituent, L1 represents a single bond or a divalent linking group, P represents a photo-aligned group, and A represents an acid-cleavage group which is decomposed by an action of acid to produce a polar group
Claims13
A photo-alignment polymer comprising a repeating unit represented by Formula (1),
- in Formula (1),
- R1 represents a hydrogen atom or a substituent,
- X represents —O—, —S—, or —NR2—, in which R2 represents a hydrogen atom or a substituent,
- L1 represents a single bond or a divalent linking group,
- P represents a photo-aligned group, and
- A represents an acid-cleavage group represented by Formula (B1) or (B2), which is decomposed by an action of acid to produce a polar group,
- in Formulae (B1) and (B2),
- * represents a bonding position,
- Lb1 and Lb2 each independently represent a single bond or a divalent linking group,
- Y represents a group containing a fluorine atom or a silicon atom, where two Y's in Formula (B1) may be the same or different from each other, and
- Rb1 and Rb2 each independently represent a hydrogen atom or a substituent, where two Rb2's in Formula (B2) may be the same or different from each other, and may be bonded to each other to form a ring.
