In order to provide a horizontal-electric-field drive-type liquid crystal display element that imparts alignment control functionality with high efficiency and exhibits superior burn-in properties, a photosensitive side-chain polymer, which expresses liquid crystallinity in a prescribed temperature range, according to the present invention includes a side chain expressed by formula (0). In the formula, G is a group selected from formula (G-1), (G-2), (G-3), and (G-4) (in the formula: a dashed line represents a bonding means; R 50 represents a group selected from a hydrogen atom, a halogen atom, an alkyl group having 1-3 carbon atoms, and a phenyl group, and may be the same or different when there is a plurality thereof; J represents O, S, NH, or NR 51 ; and R 51 represents a group selected from an alkyl group having 1-3 carbon atoms and a phenyl group). |
