<P>PROBLEM TO BE SOLVED: To provide an active matrix type organic EL display device in which improving highly accuracy can be performed, a gradation reproduction property is excellent, luminance variation can be suppressed, and display definition dignity is excellent; and to provide a method of driving the same. <P>SOLUTION: The active matrix type organic EL display device includes a plurality of image signal lines VL and a plurality of pixels. Each pixel has an organic EL diode OLED including an positive electrode connected to a high potential power source wiring, a P-channel type driving transistor DRT including a drain electrode connected to a low potential power source wiring, a capacity part Cs connected to a source electrode and a gate electrode of the driving transistor, an initialization transistor TCT switching whether initialization voltage Vini can be output ot not, and a write-in transistor SST switching whether image signal voltage Vsig supplied through the image signal line VL can be output or not. <P>COPYRIGHT: (C)2010,JPO&INPIT |
