Abstract
A liquid crystal display device includes a pair of opposing substrates, a liquid crystal layer sandwiched between the substrates, plural pixels each having a switching element and disposed in an area surrounded by first and second gate signal lines and drain signal lines. Each video information supplied for each pixel from a corresponding one of the drain signal lines is written thereinto via the switching element driven by a first scanning signal from the first gate signal line. A second scanning signal from the second gate signal line rises approximately simultaneously with fall of the first scanning signal such that disturbances introduced into one of the pixels by the first scanning signal and the second scanning signal cancel each other.
