ABSTRACT:
A light leakage is suppressed, and the effect of interference is reduced. A substrate for a reflection type liquid crystal display apparatus disposed opposite to a transparent substrate by sandwiching the liquid crystal and including a semiconductor substrate constituting the reflection type liquid crystal display apparatus, including a plurality of reflection electrodes disposed above the semiconductor substrate so as to be opposed to the transparent substrate, and a metal layer disposed between the semiconductor substrate and the reflection electrodes in order to reflect upward the light entering through a gap of the plurality of reflection electrodes from the above, wherein the metal layer has a concave portion in a region corresponding to the gap.
