A transparent screen for 3D display having excellent transparency and an excellent viewing angle, and a 3D display system are provided. The transparent screen for 3D display has a plurality of dots, each of the dots having wavelength selectivity 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, in the portion, the angle formed by the normal line to a line that is formed by a first dark part as counted from the surface of the dot on the opposite side of the substrate and the surface of the dot is in the range of 70° to 90°, and right-handed circularly polarized light and left-handed circularly polarized light are reflected by the plurality of dots.
