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 when a panel has higher definition is provided. In the light emitting device, one electrode (a second electrode) of the light emitting element having a layer containing a light emitting material interposed between a first electrode and the second electrode is electrically connected to an auxiliary wiring not only in a peripheral portion but also in a pixel portion. The layer containing a light emitting material has at least a first buffer layer, a light emitting layer, and a second buffer layer. In the pixel portion, either one or both of the first buffer layer and the second buffer layer are interposed between the auxiliary wiring (the first auxiliary wiring) and the second electrode in a connection portion (a first connection portion) where the second electrode and the auxiliary wiring (the first auxiliary wiring) are electrically connected. |
