The mechanism of the liquid crystal molecule (5CB) alignment by the polarized UV irradiated polymer film has been examined by the spectroscopic method like UV/vis and IR. Consequencely it become clear that crosslinking of polyvinylcinnamate (PVCn) fairly depends on the temperature of the substrate at the time of the UV irradiation, especially the liquid crystal alignment is improved by the use of irradiating with UV light to PVCn through heating the substrate above Tg. Moreover it is assumed that the alignment of 5CB has two mechanisms. One is that 5CB aligns due to the res-idual side-chain which don't react below Tg, the other is that above Tg the cross-linked structure aligns it.
