A light emitting device of a thin film field effect is described that can reduce a driving voltage by forming a strong dielectric buffer layer and improve the characteristic between a brightness and voltage. The light emitting device includes a transparent electrode 12, first insulating layer 13, light emitting layer 14, buffer layer 20 composed of strong dielectric material, second insulating layer 15-1 and 15-2, and metal electrode 6, which are formed over a glass substrate 11. The buffer layer 20 is composed of SrTiO3 and has a thickness not more than 2000 angstrom. The second insulating layer 15-1 and 15-2 are made of composite with two layers. Thereby, it is possible to make the driving of the device easy. |
