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 n th ( 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 n th wiring groups having M ( M is a natural number of 2 or more) wirings (112_11,..,112_2 M ) 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 n th wiring groups and inputting the n analog signals to first to n th subpixels. The first to n th subpixels each include an electrode (113_1,113_2) for driving a liquid crystal element.
