Claim Text:
1. A method of manufacturing a liquid crystal display, the method comprising: a step of providing a first substrate with a first alignment film thereon, the first alignment film made of a polymer compound expressed by expression 41, 51, or 52 and including a crosslinkable functional group as a side chain and including, in a main chain, one or more sterically bulky skeletons represented by one or more expressions selected from the group consisting of expressions (1) to (11); a step of providing a second substrate with a second alignment film thereon; a step of arranging the first and second substrates with the first alignment film and the second alignment film facing each other; a step of introducing liquid crystal including liquid crystal molecules, between the arranged first and second alignment films to form a liquid crystal layer; a step of sealing the liquid crystal layer between the first alignment film and the second alignment film; and a step of cross-linking the side chain of the polymer compound after the step of sealing the liquid crystal layer by applying ultraviolet light to first alignment film while applying a voltage or magnetic field across the liquid crystal layer so as to pretilt the liquid crystal molecules, thereby providing a pretilt function by the first alignment film without application of linearly polarized light or light in an oblique direction to the first and second alignment films, where expression 41 is: where expressions 51 and 52 are: where expressions (1) to (11) are:
