Patent ID: 7420647

Claim:
A method for producing a liquid crystal display device comprising the steps of: sealing a liquid crystal containing a polymerizable component capable of being polymerized with heat or light between a pair of substrates having been disposed as being opposed to each other; polymerizing the polymerizable component by irradiating the liquid crystal with light of a prescribed luminance at a prescribed temperature for a prescribed irradiating time under application of a prescribed voltage, so as to control a pretilt angle and a tilt direction of liquid crystal molecules; and measuring a thickness of a cell or a height of a pillar spacer formed on one of the pair of substrates before and/or after injecting the liquid crystal, wherein at least one of the voltage, the temperature, the luminance and the irradiation time is controlled as a parameter to obtain prescribed optical characteristics, and the parameter is controlled, while polymerizing the polymerizable component, under feedback of a measured thickness of the cell or a measured height of the pillar spacer.
