The lighting device disclosed in the embodiment includes a substrate, a light emitting device disposed on a lower surface of the substrate, a reflective layer disposed to face a light emitting surface of the light emitting device, a first resin layer disposed between the substrate and the reflective layer, and a light-transmission control layer disposed on an upper surface of the substrate, wherein the light-transmission control layer may include a liquid crystal layer including a cholesteric liquid crystal, and light emitted through the light emitting surface of the light emitting device may be reflected by the reflective layer and be provided to the light-transmission control layer through the substrate.

A lighting device for a vehicle, comprising at least one light source, a flat light guide with an input surface and at least one output surface. The light generated by the at least one light source enters the light guide at least partially through the input surface and exits at least partially from the at least one output surface. An LC display which has two opposing, at least partially transparent plates and a liquid crystal layer is arranged between these plates. One of the at least partially transparent plates of the LC display is formed by the flat light guide. The lighting device is configured such that the light emerging from the at least one output surface of the light guide passes at least partially through the liquid crystal layer of the LC display and subsequently through the LC display plate not formed by the light guide.

A vehicle lamp that reflects or obstructs light using a film filled with metal flakes, thereby emitting light in a preset pattern includes a light source that emits light, a main film disposed in a light emission path of the light source, and a magnetic field generating unit that generates a magnetic field that influences the main film. The main film includes a functional layer that selectively transmits the light depending on the magnetic field.
