<P>PROBLEM TO BE SOLVED: To provide a display device using a current driving type light emitting element such as an organic EL element, in which degradation in contrast due to an excessive or insufficient luminance value of black can be prevented by a simple configuration. <P>SOLUTION: A plurality of reference voltages V0 to V15 are generated by resistive division of source reference voltages VRT, VRB, VR, VG, VB, and the plurality of reference voltages V0 to V15 are selected to subject image data DR, DG, DB to digital-analog conversion process so that at least the source reference voltage VRB for the black level is made common in each color data DR, DG, DB. The source reference voltages VR, VG, VB for setting an intermediate grayscale nearer to the black level are individually variable for the respective color data DR, DG, DB. <P>COPYRIGHT: (C)2008,JPO&INPIT |
