Abstract: A liquid crystal display device includes a first substrate, a second substrate, and a liquid crystal layer. The first substrate includes a reflective layer, a first electrode and a second electrode configured to generate a transverse electrical field in the liquid crystal layer, and a first horizontal alignment film. An electrode, of the first electrode and the second electrode, disposed on a side of the liquid crystal layer includes a plurality of belt-shaped portions and a slit positioned between two adjacent belt-shaped portions of the plurality of belt-shaped portions, the liquid crystal layer is constituted by a liquid crystal material including a liquid crystal molecule, the liquid crystal material is a positive type. The second substrate includes a second horizontal alignment film being in contact with the liquid crystal layer, and the liquid crystal layer takes a twist alignment when no voltage is applied.
