Abstract
The present disclosure relates to a slit grating, a method for manufacturing the same and a display device. The slit grating includes an upper substrate, a lower substrate, an electric-controlled dielectric layer and a liquid composite layer arranged between the upper substrate and the lower substrate. The liquid composite layer consists of a light-shielding liquid and a light-transmitting liquid incompatible with each other. The electric-controlled dielectric layer has an electrically-induced light-shielding-liquid-philic or light-shielding-liquid-phobic property.
