Abstract

A liquid crystal display device includes a first substrate having a first electrode and a second electrode, a second substrate, a liquid crystal interposed between the first substrate and the second substrate, pixels each having a transmissive portion for performing a transmissive display and a reflective portion for performing a reflective display, and a driving circuit driving the pixels. Here, a third electrode is disposed in the second substrate opposed to the first substrate with the liquid crystal interposed therebetween. The first electrode is disposed in the transmissive portion along with the second electrode and is also disposed in the reflective portion along with the third electrode. The driving circuit is provided to independently apply potentials to the second electrode and the third electrode.
