Patent ID: 8064019

Claim:
A production method of a liquid crystal display device comprising a first substrate; a second substrate facing to the first substrate; a liquid crystal layer provided between the first and the second substrates; a first alignment film provided on the liquid crystal layer side surface of the first substrate; and a second alignment film provided on the liquid crystal layer side surface of the second substrate, at least one of the first alignment film and the second alignment film being a photo-alignment film providing liquid crystal molecules with pretilt angles in response to photo irradiation, the method comprising: a step of scanning exposure, the scanning exposure being defined by exposing the first alignment film and/or the second alignment film while scanning a spot of a light beam linearly continuously over a plurality of pixels on the surface of the first substrate and/or the second substrate, wherein the scanning exposure scans an inside of each pixel more than one time along a first direction and a second direction parallel and reverse to the first direction, whereby the scanning exposure forms a plurality of regions dividing alignment of the liquid crystal molecules in the inside of the each pixel, the liquid crystal molecules aligning parallel and reverse to each other in the plurality of region.
