摘要： The present invention provides a liquid crystal display device having improved transmittance. The liquid crystal display device according to the present invention has a first substrate and a second substrate disposed to face each other, and a liquid crystal layer interposed between the first substrate and the second substrate. The first substrate includes a pixel electrode to which a signal voltage is supplied and a common electrode to which a common voltage is supplied. The pixel electrode and the common electrode both comprise comb teeth. The comb teeth of the pixel electrode and the comb teeth of the common electrode are disposed with each other alternately via an interval. The liquid crystal layer contains liquid crystal molecules having positive dielectric anisotropy. The liquid crystal molecules are aligned in a direction orthogonal to a surface of the first substrate in a voltage non-application condition. The first substrate includes an extension wiring provided in a position overlapping at least one comb tooth of the comb teeth of the pixel electrode and the common electrode so as to extend along the at least one comb tooth via an insulating film, and the extension wiring serves as a wiring to which the signal voltage is supplied.
