Display device, liquid crystal display device and electronic device including the same

摘要

A liquid crystal display device includes a pixel having a first to nth (n is a natural number of 2 or more) subpixels and a circuit (100). To the circuit, N (N is a natural number of 2 or more) wirings (111_1,111_N) for supplying a digital signal with N bits and first to nth wiring groups having M (M is a natural number of 2 or more) wirings (112_11,..,112_2M) for supplying M different voltages are electrically connected. The liquid crystal display device has a function of converting the digital signal into n analog signals by using the M voltages supplied to the first to nth wiring groups and inputting the n analog signals to first to nth subpixels. The first to nth subpixels each include an electrode (113_1,113_2) for driving a liquid crystal element.
