Liquid crystal display device

A liquid crystal display device, comprising:

• an array substrate including:
• a gate line extending in a first direction,
• a source line extending in a second direction orthogonally crossing the first direction,
• an auxiliary capacitance line having a trunk portion extending in the first direction so as to cross the source line and a branch portion branched from the trunk portion and extending along the source line,
• a switching element formed in a region in which the source line crosses the gate line each other, the switching element including a drain line extending under the source line and arranged under the auxiliary capacitance line so as to face the trunk portion and the branch portion thereof, and
• a pixel electrode having a main pixel electrode extending substantially in parallel to the source line so as to adjoin the source line and a contact portion electrically coupled with the drain line, a portion of the main pixel electrode facing the branch portion of the auxiliary capacitance line through an insulating layer;
• a counter substrate facing the first substrate;
• and
• a liquid crystal layer held between the array substrate and the counter substrate and containing liquid crystal molecules.
