Abstract: A liquid crystal display device includes a first substrate and a second substrate. The first substrate includes a gate line and an auxiliary capacitance line extending in a first direction, a source line extending in a second direction orthogonally crossing the first direction, and a pixel electrode having a main pixel electrode arranged on the auxiliary capacitance line and extending in the first direction. The second substrate includes a common electrode having a main common electrode arranged above the gate line and extending in the first direction. A liquid crystal layer is held between the first substrate and the second substrate having liquid crystal molecules.
