Abstract
A method for manufacturing a liquid crystal display device using a liquid crystal composition containing a polar compound having a polymerizable group. Upon manufacturing the liquid crystal display device including a pair of substrates that have no alignment film and arranged to face each other, and including a liquid crystal composition containing a liquid crystal compound and a polymerizable compound as a liquid crystal layer formed between the substrates formed of an electrode group formed on either one or both of surfaces faced by each of the pair of substrates, in which at least one of the polymerizable compounds is a compound having a polar anchor group, wherein the polymerizable compound is allowed to react under conditions of 10 or more in an accumulated light quantity ratio (313 nm/254 nm) at 254 nanometers and 313 nanometers to form an alignment control layer.
