Display device

A display device comprising:

• a display panel;
• a drive circuit which drives respective pixels of the display panel;
• a control circuit which outputs display data to the drive circuit;
• a random number generating circuit which is provided to the control circuit;
• a memory element which stores initial values of the random number generating circuit;
• and
• a noise generating circuit into which signals generated by the random number generating circuit are inputted, wherein the random number generating circuit includes n pieces of shift registers,
• a basic clock of n pieces of shift registers is an intermittent drive clock which intermittently repeats stopping thereof, and
• the control circuit outputs an inversion control signal indicative of inversion of the display data.

A display device comprising:

• a display panel:
• a touch panel which overlaps with the display panel in plane;
• a drive circuit which drives respective pixels of the display panel;
• a control circuit which outputs display data to the drive circuit;
• a random number generating circuit which is provided to the control circuit;
• a memory element which stores initial values of the random number generating circuit;
• and
• a noise generating circuit into which signals generated by the random number generating circuit are inputted, wherein the random number generating circuit includes n pieces of shift registers,
• a basic clock of n pieces of shift registers is an intermittent drive clock which intermittently repeats stopping thereof,
• the noise generating circuit changes frequency of signals generated by the random number generating circuit, and
• the control circuit outputs a noise control signal and controls the number of inversion of the display data.
