A liquid crystal display device includes 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 tranmissive display portion for performing a tranmissive display operation and a reflective display portion for performing a reflective display operation, a first electrode provided in the first substrate, a second electrode provided in the first substrate and a third electrode provided in one of the first substrate and the second substrate. The first electrode is arranged both in the tranmissive display portion and in the reflective display portion. The second electrode is arranged in the tranmissive display portion. The first electrode and the second electrode are 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 is provided with a plurality of slits formed to extend along a perpendicular axis that is perpendicular to an interface of the tranmissive display portion and the reflective display portion. The third electrode is arranged in the reflective display portion. The second electrode and the third electrode are configured to be provided with voltage independently.
