CORRECTION METHOD OF ALIGNMENT LAYER, CORRECTION APPARATUS OF ALIGNMENT LAYER AND MANUFACTURING METHOD OF LIQUID CRYSTAL PANEL

摘要

PROBLEM TO BE SOLVED: To provide a correction method of an alignment layer capable of accurately detecting a defect in the alignment layer and correcting it.SOLUTION: A correction method of a defect of an alignment layer includes: a step (a) of acquiring an image of a pixel pattern (a repeated pattern) in the surface of the alignment layer formed on the surface of a substrate; a step (b) of acquiring adjacent images (four images positioned vertically and horizontally) around the image of the pixel pattern; a step (c) of synthesizing the image of the pixel pattern and an image connecting the adjacent images; and a step (d) of specifying the defect of the alignment layer by comparing the image of the pixel pattern in the connected images with the adjacent images.
