It is an object of the present invention to provide a substrate for liquid crystal display by means of which a generation of air bubbles in a liquid crystal layer after charging a liquid crystal can be prevented, and a liquid crystal display having a good display quality level can be obtained at a high yield, and to provide a liquid crystal display unit provided with such substrate for liquid crystal display. The present invention is directed to a substrate for liquid crystal display, comprising a projection for controlling alignments of liquid crystal molecules, wherein a slit is provided in the projection for controlling alignments of liquid crystal molecules.
