Claim 22:
23. A display device, comprising:
a first voltage source providing a first voltage;
a second voltage source providing a second voltage, the second voltage different from the first voltage;
a timing controller;
a data driver connected to a first data line and a second data line different from the first data line; and
a display unit comprising:
a first pixel circuit coupled to the first data line, the first pixel circuit including a first driving transistor, a first initialization transistor, a first anode initialization transistor, and a first light emitting diode emitting a first color, the first light emitting diode including a first anode and a first cathode; and
a second pixel circuit coupled to the second data line, the second pixel circuit including a second driving transistor, a second initialization transistor, a second anode initialization transistor, and a second light emitting diode emitting a second color different from the first color, the second light emitting diode including a second anode and a second cathode, wherein
the first voltage is applied to the first anode through the first anode initialization transistor,
the second voltage is applied to the second anode through the second anode initialization transistor, and
a cathode voltage commonly applied to the first cathode and the second cathode is smaller than the first voltage.
