Liquid crystal display device

A liquid crystal display device, comprising:

• a liquid crystal display panel including a first substrate and a second substrate facing each other, and a liquid crystal layer provided between the first substrate and the second substrate;
• the liquid crystal display device including a plurality of pixels arrayed in a matrix;
• wherein:
• the first substrate includes a first electrode provided in each of the plurality of pixels and a second electrode provided below the first electrode with an insulating layer being provided between the first electrode and the second electrode, the second electrode generating a lateral electric field in the liquid crystal layer together with the first electrode;
• the second substrate includes a third electrode provided to face the first electrode and the second electrode, the third electrode generating a vertical electric field in the liquid crystal layer together with the first electrode and the second electrode;
• the plurality of pixels each exhibit, in a switched manner,
• a black display state where black display is provided in a state where the vertical electric field is generated in the liquid crystal layer,
• a white display state where white display is provided in a state where the lateral electric field is generated in the liquid crystal layer, and
• a transparent display state where a rear side of the liquid crystal display panel is seen through in a state where no voltage is applied to the liquid crystal layer;
• and
• a potential difference between the first electrode and the second electrode at each gray scale level from a lowest level to a highest level is 60% or less of a potential difference between the second electrode and the third electrode in the black display state.
