A light emitting device which includes a first TFT, a second TFT, a first pixel electrode, a second pixel electrode, an organic compound layer, a first opposing electrode and a second opposing electrode. The organic compound layer is formed on the first pixel electrode and the second pixel electrode. The first opposing electrode and a second opposing electrode are formed on the organic compound layer. When the first pixel electrode and the second opposing electrode are anodes, the second pixel electrode and the first opposing electrode are cathodes. When the first pixel electrode and the second opposing electrode are cathodes, the second pixel electrode and the first opposing electrode are anodes.
