Abstract
A method for manufacturing LCD panels includes providing upper and lower substrates; interposing a liquid crystal material composed of at least one liquid crystal molecule and at least two photosensitive monomers between the upper and lower substrates, at least one first photosensitive monomer having an absorption peak larger than 300 nm and at least one second photosensitive monomer having an absorption peak smaller than 300 nm; applying a voltage between the upper and lower substrates and irradiating with ultra-violet radiation having a first wavelength larger than 300 nm for a first time interval for polymerizing most first photosensitive monomers to provide an alignment polymer; and separately irradiating with ultra-violet radiation having a second wavelength for a second time interval, the second wavelength being larger than the first wavelength. The Irradiating steps are separate and, when irradiating with the first wavelength precedes irradiating with the second wavelength, residual monomers are reduced.
