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
104b) 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.
