To provide a light emitting device having a highly definite pixel portion. An anode ( 102 ) and a bank ( 104 ) orthogonal to the anode ( 102 ) are formed on an insulator ( 101 ). A portion of the bank ( 104 ) (controlling bank 104 b ) is made of a metal film. By applying a voltage thereto, an electric field is formed, and a track of an EL material that is charged with an electric charge can be controlled. Thus, it becomes possible to control a film deposition position of an EL layer with precision by utilizing the above method. |
