ABSTRACT:
The invention provides a retardation-controlling optical member that includes a retardation layer obtained by aligning and fixing crosslinkable liquid crystal molecules and columnar structures disposed on the retardation layer. When a liquid crystal cell is formed by use of the retardation-controlling optical member, the columnar structures are effectively inhibited from subsiding in the retardation layer to locally make the cell gap smaller even when pressure is externally applied in a thickness direction of the liquid crystal cell. A sum total of lower bottom areas of columnar structures disposed on a retardation layer is made larger sufficiently compared to a total area of, in particular, an effective display region of a retardation layer surface where the columnar structures are disposed, whereby pressure applied from a thickness direction is dispersed.
