Abstract:
1. A liquid crystal display device including a thin film transistor placed above a substrate, comprising: a gate line electrically connected to a gate electrode of the thin film transistor; a gate insulating layer to cover the gate line; a source line placed above the gate insulating layer and electrically connected to a source electrode of the thin film transistor, the source line extending in a length direction of the device across a plurality of pixels; an interlayer insulating layer to cover the source line; a pixel electrode having a comb shape or a slit shape and electrically connected a drain electrode of the thin film transistor 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, the second counter electrode extending over the source line in the length direction across the plurality of pixels.
