Abstract
A decorative film includes a film body and a decorative layer. The film body is made of a transparent or semi-transparent material. The decorative layer is disposed at the film body and includes a texture layer and/or a semi-transparent colored ink layer, where the texture layer is transparent or semi-transparent. When the light-emitting element emits no light, the texture layer enables the decorative film to present at least one of a pattern effect, a dazzle effect, a matt effect, or a color-change effect, and the semi-transparent colored ink layer enables the decorative film to present the same color as the semi-transparent colored ink layer. When the decorative film is applicable to the light-emitting module, the decorative film covers the light-emitting surface of the light-emitting element, which can not only protect the light-emitting element, but also decorate the light-emitting module in a non-light-emitting state.
