摘要:
The present invention provides a liquid crystal display device capable of preventing occurrence of flickers. The liquid crystal display device including a first substrate and a second substrate disposed to face each other, and a liquid crystal layer sandwiched between the first substrate and the second substrate, wherein the liquid crystal layer includes a liquid crystal molecule having positive dielectric anisotropy; the liquid crystal molecule is perpendicularly aligned relative to a surface of the first substrate when no voltage is applied; the first substrate includes a pixel electrode to which an image signal is supplied, a common electrode to which a common signal is supplied, an insulating film, and a lower layer wiring connected to the pixel electrode; the lower layer wiring, the insulating film, and the common electrode are stacked in the stated order towards the liquid crystal layer side; the image signal is supplied to the pixel electrode through the lower wiring; the pixel electrode has a pixel comb-tooth portion; the common electrode has a common comb-tooth portion; the pixel comb-tooth portion and the common comb-tooth portion are planarly disposed to face each other in a pixel; the liquid crystal device has at least two regions having spacings of different lengths between the pixel electrode and the common electrode from each other in the pixel; the lower layer wiring overlaps the common comb-tooth portion and extends along the common comb-tooth portion; and a width of a part of the lower layer wiring which is overlapped with the common comb-tooth portion is substantially the same as or smaller than a width of a part of the common comb-tooth portion which is overlapped with the lower layer wiring.
