Abstract
To realize a random number generating circuit that is optimum for a liquid crystal display device that is used in a terminal device that includes a display/input component. A liquid crystal display device includes a liquid crystal display panel, a control circuit and a random number generating circuit, the random number generating circuit comprises plural shift registers, an output circuit and a register that stores an initial value, and the random number generating circuit is equipped with plural initial values, whereby the randomness of the random numbers is improved. Further, it becomes possible to increase and output frequencies by the output circuit because it is possible to output respectively different random numbers from the plural shift registers.
