The light guide carrier can be formed on the surface of the resin film or the transparent plate by vacuum evaporation, sputtering or 3D printing to form the transparent luminous film. The thickness of the resin film is, for example, 0.01mm to 0.1mm, but is not particularly limited. When the thickness of the resin film is set to the range, the light emission luminance of the light guide support can be ensured without impairing the transparency of the transparent light emitting film.

In one embodiment of the present application, the resin used for the resin film is preferably a thermoplastic resin. The thermoplastic resin may be a polyvinyl acetal resin, an ethylene-vinyl acetate copolymer resin, an ionomer resin, a polyurethane (polyurethane) resin, a thermoplastic elastomer, or the like, but is not particularly limited.

For example, the resin film may contain additives such as an antioxidant, an adhesive force adjuster, an ultraviolet absorber, an infrared absorber, and an antistatic agent, as needed. As an example, the glass substrate is not particularly limited as long as it can be used for a transparent luminescent film, and inorganic glass or organic glass can be used.

When the transparent luminescent glass has more than 2 glass substrates, the plurality of glass substrates may be made of the same material or different materials. For example, when there are 2 glass substrates, one of them may be inorganic glass and the other may be organic glass. Wherein, in the case of having a plurality of transparent plates, the plurality of glass substrates are preferably made of inorganic glass or organic glass. The thickness of each transparent plate is not particularly limited, and is, for example, about 0.1 to 15mm, preferably 0.5 to 5 mm. When the transparent luminescent film has a plurality of glass substrates, the thicknesses of the glass substrates may be the same or different.

For example, the transparent luminescent film may be one that transmits visible light or one that does not transmit visible light, but preferably transmits visible light. The visible light transmittance means, for example, a visible light transmittance of 30% or more, preferably 50% or more. When the transparent luminescent film is used for, for example, a front glass, a front side glass, or the like of an automobile, the visible light transmittance is preferably 70% or more, more preferably 75% or more, and further preferably 80% or more from the viewpoint of enhancing the transparency of the transparent luminescent film and from the viewpoint of ensuring the safety of the automobile. The upper limit of the visible light transmittance is not particularly limited, and the higher the visible light transmittance, the better the visible light transmittance is, in practice, preferably 99% or less, and more preferably 95% or less. Furthermore, the transmittance of visible light means the average transmittance of visible light of 400 to 780 nm.

As an example, the transparent light emitting film may emit visible light by incident LED light from a light source as described above. The visible light is generally light having a wavelength of 400 to 780 nm. The transparent luminescent film may emit blue, green, red, or the like, or may emit white light by mixing 2 or more colors of light. When light of 2 or more colors is mixed, for example, 2 or more light emitting layers may be provided, and each layer may be irradiated with different light to mix the colors, but 2 or more fluorescent materials may be contained in 1 light emitting layer.
