Classification: CPC G | IPC G

Claim 7:
8. A liquid crystal display device comprising:
a liquid crystal panel provided with sub-pixels arranged in a matrix pattern; and
a control circuit,
wherein the liquid crystal panel sequentially includes an active matrix substrate, a liquid crystal layer, and a color filter substrate,
the active matrix substrate sequentially includes a first substrate, a first electrode, a first insulating layer, and second electrodes arranged in the respective sub-pixels and including a first linear electrode extending in a first direction,
the color filter substrate includes a second substrate, a black matrix lying between the sub-pixels, a color filter layer, a third electrode including second linear electrodes and a third linear electrode between the second linear electrodes, and a fourth electrode which is a floating electrode,
the third electrode and the fourth electrode are disposed between the black matrix and the liquid crystal layer,
the second linear electrodes extend in a second direction that intersects the first direction and each overlaps a portion of the black matrix extending in the second direction,
the fourth electrode is disposed in the same layer as the third electrode and between the second linear electrodes and overlaps at least a portion of the black matrix in a plan view,
the control circuit is configured to switch between an application of a driving voltage and an application of a constant voltage to the third electrode, and
the third linear electrode extends in the second direction and overlaps an optical opening in one of the sub-pixels in the plan view.
