During first period, TFTs:<img id="CUSTOM-CHARACTER-00001" he="3.56mm" wi="4.23mm" file="US20090141204A1-20090604-P00001.TIF" img-content="character" img-format="tif"/> and <img id="CUSTOM-CHARACTER-00002" he="3.13mm" wi="4.23mm" file="US20090141204A1-20090604-P00002.TIF" img-content="character" img-format="tif"/> are set in ON and OFF states, respectively. Potential Va is fed into a source line Sj so that potential of pixel electrode is Va. During second period, the TFTs:<img id="CUSTOM-CHARACTER-00003" he="3.56mm" wi="4.23mm" file="US20090141204A1-20090604-P00001.TIF" img-content="character" img-format="tif"/> and <img id="CUSTOM-CHARACTER-00004" he="3.13mm" wi="4.23mm" file="US20090141204A1-20090604-P00002.TIF" img-content="character" img-format="tif"/> are set in the OFF and ON states, respectively. The potential Va is continuously fed into the source line Sj. This sets potential of node to Va, thereby changing the potential of the pixel electrode. During third period, the TFTs:<img id="CUSTOM-CHARACTER-00005" he="3.56mm" wi="4.23mm" file="US20090141204A1-20090604-P00001.TIF" img-content="character" img-format="tif"/> and <img id="CUSTOM-CHARACTER-00006" he="3.13mm" wi="4.23mm" file="US20090141204A1-20090604-P00002.TIF" img-content="character" img-format="tif"/> are set in the OFF state. This realizes a display device where high cost factors and power consumption increase are suppressed, and the effective value of voltage expressed by difference between potential applied to a driving potential input terminal and reference potential can have variance larger than amplitude of signal voltage fed into a data signal line, the variance corresponding to variation in the signal voltage.
