Abstract
The present invention provides a liquid crystal display device for which laser repair can be easily performed to correct a defect pixel, and/or a liquid crystal display device capable of reducing generation of contact failure and a short circuit. The liquid crystal display device of the present invention includes a first substrate, a liquid crystal layer, and a second substrate in the given order. The first substrate includes: an insulating substrate; a scanning line; a data line; a first insulating film disposed between the scanning line and the data line; a common line extending in an extension direction of the scanning line or the data line; a counter electrode facing the common line with the first insulating film in between; a switching element being connected to the scanning line and the data line; a second insulating film; a pixel electrode being connected to the switching element and the counter electrode; a third insulating film; and a common electrode being provided with an opening. The switching element, the second insulating film, the pixel electrode, the third insulating film, and the common electrode are disposed in the given order toward the liquid crystal layer.
