ABSTRACT:
An apparatus for determining orientation of an alignment layer in a pixel unit of an LCD device is provided. The pixel unit includes a glass substrate having an outer surface provided with the alignment layer treated by photolithographic masking and rubbing operation. The apparatus includes a conveyor belt for feeding the alignment layer; a steam-generating device disposed above the conveyor belt in such a maimer that the alignment layer is formed with a plurality of water drops or water layer when passed underneath the steam-generating device; a light source for providing light beams into the water drops on the alignment layer; and an image catcher for fetching an image data formed on the alignment layer by virtue of light reflection and refraction of the water drops hanging on the alignment layer.
