Abstract:
1. A liquid crystal display device comprising: a first substrate including a gate line extending in a first direction, a storage capacitance line spaced apart from the gate line, a first interlayer insulation film covering the gate line and the storage capacitance line, a source line located on the first interlayer insulation film and extending in a second direction crossing the first direction, a switching element which is electrically connected to the gate line and the source line and includes a drain electrode located on the first interlayer insulation film, spaced apart from the source line and opposed to the storage capacitance line, a second interlayer insulation film covering the source line and the drain electrode, a pixel electrode which is located on the second interlayer insulation film and includes a main pixel electrode extending in the second direction and a sub-pixel electrode which extends in the first direction at a position inside a position above an edge of the drain electrode and is put in contact with the drain electrode, and a first alignment film covering the pixel electrode; a second substrate including a common electrode, which includes a main common electrode extending in the second direction on both sides of the main pixel electrode, and a second alignment film covering the common electrode; and a liquid crystal layer held between the first substrate and the second substrate, wherein the switching element includes a semiconductor layer extending under the storage capacitance line, the storage capacitance line comprises an aperture portion, the drain electrode is electrically connected to the semiconductor layer via the aperture portion, and the sub-pixel electrode is electrically connected to the drain electrode in a region opposed to the storage capacitance line.
