Each pixel includes: a light emitting element; a capacitor; a driving
transistor that has a control terminal, an input terminal, and an output
terminal and supplies a driving current to the light emitting element to
emit light; a first switching unit that diode-connects the driving
transistor and supplies a data voltage to the driving transistor in
response to a scanning signal; and a second switching unit that supplies
a driving voltage to the driving transistor and connects the light
emitting element and the capacitor to the driving transistor in response
to an emission signal, wherein the capacitor is connected to the driving
transistor through the first switching unit, stores a control voltage
being a function of the data voltage and the threshold voltage of the
driving transistor, and is connected to the driving transistor through
the second switching unit to supply the control voltage to the driving
transistor.
