Abstract
A liquid crystal display device includes a first substrate, a second substrate disposed on a viewer side relative to the first substrate, a liquid crystal layer provided between the first substrate and the second substrate, a polarizer disposed on the viewer side relative to the liquid crystal layer, and a phase difference layer disposed between the polarizer and the liquid crystal layer, and also includes a plurality of pixels arrayed in a matrix shape. The first substrate includes a reflective layer that reflects light, a first electrode and a second electrode that can generate a transverse electrical field in the liquid crystal layer, and a first horizontal alignment film in contact with the liquid crystal layer. The second substrate includes a second horizontal alignment film in contact with the liquid crystal layer. The liquid crystal layer takes a twist alignment when no voltage is applied.
