<P>PROBLEM TO BE SOLVED: To provide a light emitting display apparatus and a pixel circuit, capable of preventing luminance unevenness of the light emitting display apparatus by making a current amount flowing to a light emitting element constant. <P>SOLUTION: The pixel circuit includes; a light emitting element OLED; a driving transistor M4 to receive and supply current in corresponding to voltage applied to a gate electrode thereof from first power source to the light emitting element; a first switching element M1 to transfer a data signal in response to a first scan signal; a second switching element M2 to supply second power source to the driving transistor in response to the first scan signal; a capacitor to store voltage corresponding to the data signal and the second power source according to operations of the first and second switching elements M1 and M2; a third switching element M3 to apply the voltage stored in the capacitor to the driving transistor M4 in response to a second scan signal; and a fourth switching element M5 to transfer the first power source to the driving transistor in response to a third scan signal. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
