<p><P>PROBLEM TO BE SOLVED: To provide an LCD panel driving circuit that can avoid gradation irregularity of an LCD panel even if the driving circuit is highly integrated. <P>SOLUTION: The LCD panel driving circuit includes a plurality of supply signal lines and feedback signal lines provided for respective differential driving amplifiers, wherein the driving amplifier generates a gradation signal based on a write potential inputted to one of the input terminals. The supply signal lines supply, to the gradation signal lines, the gradation signals outputted by the differential driving amplifiers through first connection points. The feedback signal lines input a potential at a second connection point arranged at the different position from a first connection point, to the other differential input terminal of the differential driving amplifier. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
