ABSTRACT:
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 bank104b) 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.
