Abstract:
1. A liquid crystal display device comprising: a first substrate including a first insulative substrate, a first signal wiring line and a second signal wiring line each extending in a first direction on an inside of the first insulative substrate, a third signal wiring line extending in the first direction on the inside of the first insulative substrate and located at a substantially middle point between the first signal wiring line and the second signal wiring line, a first insulation film covering the first signal wiring line, the second signal wiring line and the third signal wiring line, a fourth signal wiring line and a fifth signal wiring line each extending on the first insulation film in a second direction which is substantially perpendicular to the first direction, a second insulation film covering the fourth signal wiring line and the fifth signal wiring line, a switching element electrically connected to the first signal wiring line and the fourth signal wiring line, a first electrode extending in the second direction on the second insulation film, a sub-electrode extending from the first electrode toward the fourth signal wiring line and the fifth signal wiring line and electrically connected to the switching element, and a first alignment film covering the first electrode and the sub-electrode; a second substrate including a second insulative substrate, a second electrode extending in the second direction and opposed to the fourth signal wiring line and the fifth signal wiring line on that side of the second insulative substrate, which is opposed to the first substrate, and a second alignment film covering the second electrode; a liquid crystal layer including liquid crystal molecules held between the first substrate and the second substrate; a first polarizer which is disposed on an outer surface of the first insulative substrate and includes a first polarization axis which is substantially parallel to the first direction or the second direction; and a second polarizer which is disposed on an outer surface of the second insulative substrate and includes a second polarization axis having a positional relationship of crossed Nicols with the first polarization axis.
