<P>PROBLEM TO BE SOLVED: To decrease the number of fixed potential wiring patterns for scanning of a display in a current driving type spontaneous light emitting display emitting its light such as an organic EL (Electro Luminescence) element. <P>SOLUTION: A gate voltage Vg of a transistor TR2 driving a light emitting element 8 is set to a constant potential Vofs to correct the emitted light brightness variations caused by the variations of the threshold voltage Vth of this transistor TR2. This fixed potential Vofs is supplied from the signal line SIG. <P>COPYRIGHT: (C)2008,JPO&INPIT |
