ABSTRACT:
An active matrix light emitting device of which luminance characteristic does not vary among light emitting elements of respective pixels, and which can be realized even in a high definition display panel is disclosed. In the light emitting device, a light emitting material is interposed between a first electrode and a second electrode electrically connected to an auxiliary wiring, not only in a peripheral portion but also in a pixel portion. A layer containing the light emitting material comprises a first buffer layer, a light emitting layer, and a second buffer layer. In the pixel portion, either one or both of the first and the second buffer layer are interposed between the auxiliary wiring and the second electrode where the second electrode and the auxiliary wiring are electrically connected.
