LIQUID CRYSTAL DISPLAY DEVICE, PIXEL CIRCUIT, AND DRIVING METHOD

摘要

A liquid crystal display device includes: pixels each composed of n sub-pixels, the pixels being arranged in a matrix; a switching element provided for each sub-pixel; a liquid crystal element provided for each sub-pixel; n reference potential trunk lines having a mutually different magnitude of potential; a first display signal line that supplies a display signal; a scanning line; a controller; a first substrate on which the n reference potential trunk lines and the switching elements are disposed; and a second substrate on which the first display signal lines are disposed. The liquid crystal elements are formed in between the first substrate and the second substrate. A pole at one end of each liquid crystal element of the n sub-pixels is connected to the first display signal line, and a pole at the other end of each liquid crystal element of the n sub-pixels is connected to the respective first to nth reference potential trunk lines via the respective switching elements. From the scanning line, the controller supplies an on-state signal to each switching element of the n sub-pixels with the same timing.
