Grating, display device, and manufacturing method of grating
A grating including a first substrate and a second substrate oppositely disposed; a first transparent electrode having a grating structure and disposed on a side of the first substrate facing towards the second substrate; a second transparent electrode disposed on a side of the second substrate facing towards the first substrate and disposed opposite to the first transparent electrode; and a polymer layer disposed between the first transparent electrode and the second transparent electrode and containing therein nano-sized material converting electromagnetic energy into heat energy and liquid crystalline elastomers. When a voltage is applied, the nano-sized material converts electromagnetic energy into heat energy, to convert the polymer layer to cholesterol phase and reflect all the light within the wavelength range of visible light; and when no voltage is applied, the polymer layer is transparent.
