  It is a method for manufacturing a liquid crystal display device in which an anchoring force causing liquid crystal molecules to be vertically aligned can be exerted sufficiently. A liquid crystal display device ( 1 ) including two substrates AM and CF and a liquid crystal layer ( 4 ) sandwiched therebetween can be manufactured. The liquid crystal display device manufacturing method includes: a first step of subjecting a surface of one of the substrates AM and CM that is to be in contact with the liquid crystal layer ( 4 ) to hydrophilization treatment; and a second step of disposing the two substrates AM and CF so as to face each other such that the two substrates are in contact with a liquid crystal composition containing liquid crystal molecules and an alignment aid having a polar group and having the function of causing the liquid crystal molecules to be aligned spontaneously.
