<p>A pixel circuit (6) is driven in an impulse mode in which an organic EL diode (7) emits light only during a selection period, or in a hold mode in which the organic EL diode (7) emits the light not during the selection period but after the selection period. Moreover, the pixel circuit (6) is provided with a programmed current source (I1) for lower-side gray scale display and a programmed current source (I2) for higher-side gray scale display, the pixel circuit (6) being supplied with a programmed current (I) from the programmed current source (I1) when the pixel circuit (6) is driven in the impulse mode, and a programmed current (I') from the programmed current source (I2) when the pixel circuit (6) is driven in the hold mode.</p> |
