Zusammenfassung: | To provide an image projecting structure having a wide viewing angle and whereby the visibility of a projected image is high. The image projecting structure comprises a first transparent layer having irregularities formed on its surface, a reflective film formed on the surface on which the irregularities are formed, of the first transparent layer, and a second transparent layer formed on the reflective film, wherein the transmittance of visible light is from 5 to 95%; the value obtained by dividing the haze by the diffuse reflectance of visible light is at least 0.1 and at most 1; the vertical difference Sk in the core section defined by ISO 25178, of the surface on which the irregularities are formed, is at least 0.1 μm; and the value obtained by dividing the shortest autocorrelation length Sal by the vertical difference Sk in the core section is at least 1.2 and at most 190. |
