  • Light emission device including magnetoactive member, method of manufacturing the same and electronic apparatus including light emission device
    Patent number: 11454835
    Abstract: Disclosed are a light emission device including a magnetoactive element, a method of fabricating the same, and an electronic device including the light emission device. The disclosed light emission device may include a light emission layer; a first electrode and a second electrode spaced apart from each other on a first surface side of the light emission layer; and a magnetoactive fluid layer disposed on a second surface side of the light emission layer and having a plurality of nanostructures of which arrangement and distribution is configured to change according to application of a magnetic field. The light emitting properties of the light emission layer may be changed according to the arrangement and distribution of a plurality of nanostructures in the magnetoactive fluid layer. The plurality of nanostructures may include conductive nanowire and magnetic nanoparticle provided on the surfaces of the conductive nanowire.
