Abstract:
A manufacturing method of a liquid crystal display according to an exemplary embodiment of the present invention includes: a step of preparing a lower panel in which a pixel electrode is formed and which is coated with a lower alignment layer including reactive mesogen; a step of preparing an upper panel in which a common electrode is formed and which is coated with an upper alignment layer including reactive mesogen; a step of forming a display panel assembly by injecting a liquid crystal between the lower panel and the upper panel and bonding the lower panel and the upper panel; a step of pre-tilting the liquid crystal by applying a voltage to the display panel assembly and primarily irradiating ultraviolet rays having a wavelength of 310 nm to 380 nm; and a step of removing remaining reactive mesogen by secondarily irradiating ultraviolet rays having a wavelength of 300 nm to 360 nm to the display panel assembly.
