Abstract:
1. A liquid crystal display device, comprising: a first substrate; a second substrate; a liquid crystal layer arranged between the first substrate and the second substrate; a plurality of pixels each one of which has a transmissive display portion for performing a transmissive display operation and a reflective display portion for performing a reflective display operation; a first electrode provided in the first substrate, the first electrode arranged both in the transmissive display portion and in the reflective display portion; a second electrode provided in the first substrate, the second electrode arranged in the transmissive display portion, the first electrode and the second electrode configured to control an alignment of liquid crystal molecules of the liquid crystal layer, at least one of the first electrode and the second electrode provided with a plurality of slits formed to extend along a perpendicular axis that is perpendicular to an interface of the transmissive display portion and the reflective display portion; an insulating film formed on the second electrode; a reflecting plate formed on the insulating film and positioned between the first electrode and the second electrode, the reflecting film being a conductive film that is electrically connected to the first electrode; and a third electrode formed in the second substrate, the third electrode arranged in the reflective display portion, the second electrode and the third electrode configured to be provided with voltage independently, wherein the transmissive display portion is driven by a first driving method, and the reflective display portion is driven by a second driving method that is different from the first driving method, and wherein the first electrode and the second electrode are configured to hold capacitance.
