Abstract

A transparent screen includes a substrate capable of transmitting light; and a plurality of dots formed on a surface of the substrate, each of the dots having wavelength-selective reflectivity and being formed of a liquid crystal material having a cholesteric structure, in which the cholesteric structure gives a striped pattern of bright parts and dark parts in a cross-sectional view of the dot observed by a scanning electron microscope, the dot includes a portion having a height that increases continuously to the maximum height in a direction extending from the edge toward the center of the dot, the angle formed by the normal line to a line that is formed by a first one of the dark parts as counted from the surface of the dot on the opposite side of the substrate and the surface of the dot, in the portion, is in the range of 70° to 90°, and a plurality of dot row units in which two or more dots are adjacently arranged along one direction are formed.
