Liquid crystal display device
First Claim
1. A liquid crystal display device comprising:
- a first substrate;
a second substrate;
a liquid crystal interposed between the first substrate and the second substrate; and
pixels each having a transmissive portion for performing a transmissive display and a reflective portion for performing a reflective display,wherein the first substrate includes;
a plurality of data lines and a plurality of gate lines;
a plurality of switching elements disposed to form a pair corresponding to each intersection between the plurality of data lines and the plurality of gate lines;
first electrodes disposed in the reflective portion and the transmissive portion connected to output terminals of the pair of switching elements, respectively; and
a plurality of second electrodes disposed only in the transmissive portion and driving the liquid crystal by applying an electric field between the first electrodes and the second electrodes,wherein the second substrate includes a third electrode third electrode being disposed only in the reflective portion and driving the liquid crystal by applying an electric field between the first electrodes and the third electrode, andwherein the potential of the second electrode and the potential of the third electrode are opposite in phase to each other; and
wherein the third electrodes in odd rows of the gate lines and the second electrodes in even rows thereof are connected as a first common electrode terminal to each terminal to each other outside the display area and the third electrodes in the even rows of the gate lines and the second electrodes in the odd rows thereof are connected as a second common electrode terminal to each other outside the display area, andwherein the potential of the first common electrode terminal and the potential of the second common electrode terminal are opposite in phase to each other and the potential is alternated every vertical scanning period.

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.
