<P>PROBLEM TO BE SOLVED: To provide a pixel circuit that can prevent variance in luminance during high-luminance display without impairing signal write response during low-luminance display, and to provide a display device and a driving method of the pixel circuit. <P>SOLUTION: The pixel circuit 101 includes a TFT 111 and an organic EL light emitting element 113 arranged in series between a power source potential line VCCL and a reference potential GND, a TFT 112 connected between a signal line SGL and the gate of the TFT 111, and a capacitor C111 connected between the gate of the TFT 111 and the power source potential line VCCL. A one-field period is provided with N (8 or 10) sub-field SF periods to perform N-bit (2<SP>N</SP>gray scale) display, and a scan driver 104 generates signals of the N subfields SF1 to SFN; when the scan driver 104 preforms the selection, a high-level or low-level signal is applied from a data driver 103 to a signal line SGL and the signals are input to pixels in the timing. <P>COPYRIGHT: (C)2007,JPO&INPIT |
