Liquid crystal display device

A liquid crystal display device comprising:

• a liquid crystal panel;
• and
• a control circuit,
• the liquid crystal panel including sub-pixels arranged in a matrix pattern in an in-plane direction and sequentially including an active matrix substrate, a first alignment film, a liquid crystal layer containing liquid crystal molecules, a second alignment film, and a counter substrate,
• the active matrix substrate sequentially including a first substrate, a first electrode disposed for each sub-pixel, a first insulating layer, and a second electrode including a linear electrode portion,
• the counter substrate including a second substrate and a third electrode,
• the third electrode extending in a longitudinal direction of the sub-pixel at a right end or a left end of the sub-pixel with a widthwise direction of the sub-pixel defined as a left-right direction,
• a ratio of a width of the third electrode in the widthwise direction to a width of the first electrode in the widthwise direction being 0.14 or greater and 0.25 or smaller,
• the control circuit being configured to switch between application of an alternating voltage and application of a constant voltage to the third electrode.
