Abstract:
1. A liquid crystal display device comprising: a first substrate including a first gate line and a second gate line which extend in a first direction, a first source line and a second source line which extend in a second direction crossing the first direction, a switching element which is electrically connected to the first gate line and the first source line, and a pixel electrode which is located in an inside surrounded by the first gate line, the second gate line, the first source line and the second source line, the pixel electrode including a contact portion which is in contact with the switching element, two or more main pixel electrodes which extend in the first direction from the contact portion, and a connection portion which extends in the second direction and connects the main pixel electrodes; a second substrate including a common electrode including main common electrodes which are located above the first gate line, above the second gate line and above a point between the main pixel electrodes and extend in the first direction, and sub-common electrodes which are located above the first source line and above the second source line and extend in the second direction; and a liquid crystal layer including liquid crystal molecules held between the first substrate and the second substrate; wherein the pixel electrode is disposed in a pixel having a greater length in the first direction than in the second direction; wherein alignment of the liquid crystal molecules is controlled by an electric field produced between the main pixel electrodes extending in the first direction and the main common electrodes extending in the first direction; wherein the first substrate further includes a storage capacitance line which extends in the first direction between the first gate line and the second gate line and produces a capacitance between the storage capacitance line and the pixel electrode; wherein at least one of the main pixel electrodes is located above the storage capacitance line; wherein the contact portion is located on a side nearer the first source line; wherein each of the main pixel electrodes extends in the first direction from the contact portion toward the second source line; and wherein the storage capacitance line includes a protrusion opposing to the contact portion, and is located on a side nearer the first gate line.
