LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal display device that has suppressed the leakage of light before the start of display when the power is turned on.SOLUTION: The liquid crystal display device includes: a pixel electrode (242) to which a potential corresponding to a gradation value is applied for a plurality of pixels arranged in matrix in a display area via a pixel transistor of each pixel; a common electrode (243) that forms an electric field for aligning a liquid crystal composition in cooperation with the pixel electrode; a plurality of scanning signal lines Gi that are commonly connected with the gates of the pixel transistors of the plurality of pixels constituting each of a plurality of columns forming the matrix; and a driving circuit that brings the common electrode into a high impedance state after the power is turned on and before images are displayed on the display area, and then brings the potential of the scanning signal lines into a non-active potential to block the source-drain current of the pixel transistors.
