Abstract
A method of manufacturing a liquid crystal display includes: preparing a lower mother substrate, where lower cells, each including a thin film transistor, are provided on the lower mother substrate, and a lower alignment layer is disposed on the lower cells; preparing an upper mother substrate, where upper cells corresponding to the lower cells are provided on the upper mother substrate, and an upper alignment layer is disposed on the upper cells; providing a mother substrate assembly by providing a liquid crystal mixture layer between the lower and upper mother substrates and combining the lower and upper mother substrates; providing a pretilt of the liquid crystals by applying a voltage to a voltage application unit of the lower mother substrate; and curing an alignment supporting agents in the liquid crystal mixture layer or the lower and upper alignment layers by irradiating light to a side of the mother substrate assembly.
