摘要：
Disclosed herein is a liquid crystal device which includes first and second substrates which face each other and a liquid crystal layer interposed between the first substrate and the second substrate, and transitions an alignment state of liquid crystal molecules of the liquid crystal layer from a spray alignment to a bend alignment to perform display or optical modulation, the liquid crystal device including: a protrusion which is provided on at least one of the first substrate and the second substrate at the side of the liquid crystal layer and has a concave portion; and an alignment film which is provided on the surfaces of the first substrate and the second substrate at the side of the liquid crystal layer so as to cover the surface of the protrusion including the concave portion.
