An organic electroluminescent (EL) display panel which includes a pixel
circuit is provided. The pixel circuit includes a first transistor, a
second transistor, and a display element. The first transistor has
control and main electrodes and outputs a current which corresponds to a
voltage charged in at least one capacitor being provided between the
control and main electrodes. The second transistor has a second control
electrode coupled to the control electrode of the first transistor. The
second electrode is diode-connected. The display element displays image
data corresponding to an amount of the current output by the first
transistor. The first transistor and the display element are electrically
decoupled during the first period for applying a pre-charge voltage to
the control electrode of the first transistor and the second period for
applying the data voltage to the control electrode of the first
transistor.
