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 liquid crystal layer containing liquid crystal molecules, and a counter substrate,
• the active matrix substrate including a first substrate, a gate line, a first electrode, and a second electrode, the first electrode and the second electrode being stacked with an insulating layer in between,
• the counter substrate including a second substrate and a third electrode,
• each of the sub-pixels being provided with an optical opening allowing light to pass through the liquid crystal panel,
• the third electrode not being superimposed with at least a portion of the optical opening in a plan view and including a linear electrode extending along the gate line,
• in a direction perpendicular to an extending direction of the gate line, a distance between the linear electrode and the optical opening being less than D/4 and a width of the linear electrode being D/4 or less, wherein a distance between two optical openings adjacent in the direction perpendicular to the extending direction of the gate line is defined as D,
• the control circuit being configured to switch between application of alternating voltage and application of constant voltage to the third electrode.
