摘要:
A liquid crystal display device includes a gate line placed above a substrate, a gate insulating layer to cover the gate line, a source line placed above the gate insulating layer, an interlayer insulating layer to cover the source line, a comb-shaped or slit-shaped pixel electrode electrically connected a drain electrode of a TFT through a contact hole penetrating the interlayer insulating layer, a first counter electrode placed below and opposite to the pixel electrode with an insulating layer interposed therebetween to generate an oblique electric field with the pixel electrode, and a second counter electrode formed in the same layer as the pixel electrode and placed overlapping the source line in a given area to generate an in-plane electric field with the pixel electrode.
