<P>PROBLEM TO BE SOLVED: To provide, a display device and a driving method of the display device applied to, for example, an active matrix type display device of organic EL devices using poly-silicon TFTs, which obtains high brightness by driving signal lines with a drive signal with a small dynamic range. <P>SOLUTION: A voltage of the other end of a signal level storage capacitor is set beforehand by a variable reference voltage Vof that falls as a gradation for display increases, and thereafter, a gradation voltage Vsig that increases as the gradation increases according to the gradation for display is set at one end of the signal level storage capacitor. <P>COPYRIGHT: (C)2009,JPO&INPIT |
