Abstract
A liquid crystal display device includes, in sequence, a first substrate, a liquid crystal layer, and a second substrate. The first substrate, the liquid crystal layer, and the second substrate are disposed in a subpixel having a transmissive portion for performing transmissive display and a reflective portion for performing reflective display. The first substrate includes a first electrode and a second electrode. The second substrate includes a third electrode. The first electrode and the second electrode are disposed in the transmissive portion and at least the first electrode and the third electrode are disposed in the reflective portion. Alignment of the liquid crystal layer is controlled by an electric field occurring between the first electrode and the second electrode in the transmissive portion and by an electric field occurring between the first electrode and the third electrode in the reflective portion.
