Abstract
A first substrate () in a liquid crystal display device () includes a first electrode () provided in each pixel and a second electrode () generating a lateral electric field in a liquid crystal layer () together with the first electrode. A second substrate () includes a third electrode () generating a vertical electric field in the liquid crystal layer together with the first electrode and the second electrode. Each pixel exhibits, 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 a liquid crystal display panel () is seen through in a state where no voltage is applied to the liquid crystal layer. 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.
