The random number generating circuit includes a plurality of shift registers, an output circuit, and registers which holds initial values. By providing a plurality of initial values, the randomness of random numbers can be enhanced. Further, the random numbers different from each other can be outputted from the plurality of shift registers and hence, it is possible to increase the frequency and to output the increased frequency by an output circuit. Further, by adding a noise control signal which suppresses the number of inversion of a digital signal, electromagnetic wave noises generated from a liquid crystal display device can be reduced. Further, by adopting an intermittent drive clock which intermittently repeats stopping thereof as a basic clock of the plurality of shift registers, electromagnetic wave noises generated from the display device can be reduced. The basic clock may be a clock which is in synchronism with a transmission clock of the display data or a clock which is in asynchronism with a transmission clock of the display data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display device","description":"A display device includes a display panel, a control circuit and a random number generating circuit.
