Optical color-change film

An optical color-change film utilized in a liquid crystal display, wherein the liquid crystal display has a liquid crystal module;

• a bottom of the liquid crystal module is installed with a light guide module;
• the light guide module has a light guide element made of transparent substrate and having a plate-like shape;
• a top of the light guide element has a light output surface;
• one side of the light guide element has a light source at a side away from the thin side;
• a light source has a cambered reflecting plate at the side away from the light guide element;
• the optical color-change film is installed between the light output surface of the light guide element and the liquid crystal module;
• the optical color-change film has a thin film transparent substrate;
• a color-change layer is installed at a bottom of the substrate;
• a color-change layer is a transparent film mixed with pigments;
• besides, the substrate is installed with a light enhancing layer;
• the light enhancing layer is formed by a plurality of optical particles;
• and a plurality of protrusions are installed on the surface of the optical color-change film.
