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.

A device for adaptable wavelength conversion and a device for energy conversion are described. The device for adaptable wavelength conversion comprises at least one layer comprising a wavelength converting material and arranged to receive and re-emit a light beam. the device is further arranged to manipulate the at least one layer to operate in a closed state, in which a surface of the at least one layer is substantially covered with the wavelength converting material and to operate in an open state, in which the surface of the at least one layer is substantially uncovered with the wavelength converting material. The device for adaptable wavelength conversion can be applied in combination with a solar cell or photovoltaic cell thereby enabling the solar cell to receive radiation having a suitable spectrum under varying lighting conditions.
