ABSTRACT:
A production method of a substrate for a liquid crystal display in which an exposure pattern of a color filter or a black matrix is formed in a predetermined position of a TFT substrate at a high level of precision. Therefore the production method includes following steps: applying a photosensitive material for a color filter or a black matrix onto a TFT substrate; image-capturing a pixel region by an imaging unit while transporting the TFT substrate coated with the photosensitive material at a predetermined velocity by a transporting unit; detecting a reference position preset in the pixel region image-captured by the imaging unit at an image processing section of a control unit; and controlling irradiation timing of a light source in an exposure optical system by a lamp controller with reference to the detected reference position, and forming an exposure pattern of a color filter or a black matrix at a predetermined position of the TFT substrate.
