[ 21. An organic light-emitting display device, comprising:
first through third sub-pixels each comprising at least one capacitor, at least one thin-film transistor (TFT), and an organic light-emitting device (OLED) including a pixel electrode;
first, second and third switching devices including a common active layer and one of a common source electrode and a common drain electrode, the first, second and third switching devices being electrically connected to the first through third sub-pixels, respectively to apply an initializing voltage to the first, second and third sub-pixels when the first, second and third switching devices are turned on;
a planarization layer;
a via hole in the planarization layer; and
an initializing electrode disposed on a same layer as one of the pixel electrodes and electrically connected to the one of a common source electrode and a common drain electrode through the via hole to transmit the initializing voltage to the one of a common source electrode and a common drain electrode. ]
