In a light emitting diode, a scattering material-containing light guiding/scattering layer is provided which directly receives light emitted from a light emitting element. The scattering material contained in the light guiding/scattering layer irregularly reflects and scatters the incident light. The scattered light is led to a fluorescence emitting layer formed of a transparent binder containing a phosphor material. The probability of incidence of light having high optical density, which has been emitted from the light emitting element, directly to the phosphor material contained in the fluorescence emitting layer is lowered, and light can be radiated from the whole fluorescence emitting layer. Therefore, uniform light having a desired color can be radiated with high efficiency from the light emitting diode.
