摘要：
In an EL element including a light emitting layer sandwiched between upper and lower electrodes, of light emitted therefrom, light totally reflected at a light emitting layer interface is not taken out, so there is a problem in that light emission efficiency reduces. Therefore, a light scattering layer in which metal particles are dispersed is provided between an electrode and the light emitting layer. According to such a structure, the light from the light emitting layer can be scattered by the metal particles and taken out, thereby improving the light emission efficiency. When plasmon is excited in the metal particles, light confined in the light emitting layer or each layer adjacent thereto can be used, thereby improving light use efficiency.
