<P>PROBLEM TO BE SOLVED: To provide a pixel circuit, a display device, and a method for driving the pixel circuit that can stably and accurately supply current with a desired value to light emitting elements of respective pixels irrelevantly to variance in mobility, not to mention variance in threshold among active elements in the pixels, and then display an image of high quality. <P>SOLUTION: In automatic-zero operation, a TFT 115 is turned on together with a TFT 113 to connect a reference current line ISL to a driving transistor TFT 111 of a pixel through a 1st node ND 111, and variance in threshold Vth is corrected. Consequently, variance in ON current due to mobility in white display can be suppressed and uniformity with respect to mobility variance can greatly be improved. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
