US Patent 7327426 Method of manufacturing liquid crystal display

In a manufacturing method of a liquid crystal display unit, a roll of a flexible polymeric substrate having transparent electrodes and a longitudinal length longer than a transversal width is provided. The flexible polymeric substrate is continuously fed from the roll in the longitudinal direction while sequentially forming a vertical orientation film on the flexible polymeric substrate, solidifying the vertical orientation film, and prescribing a falling direction of liquid crystal molecules in the vertical orientation film.
