Patent ID: 7126658

Claim:
A liquid crystal display device, comprising: a first substrate; a second substrate; a liquid crystal layer sandwiched between the first and second substrates, the liquid crystal layer including liquid crystals having negative dielectric anisotropy; at least one first-substrate side electrode between the first substrate and the liquid crystal layer; and a first dot region including a first second-substrate side electrode interposed between the second substrate and the liquid crystal layer, a first transmissive display region to perform transmissive display, and a first reflective display region to perform reflective display, the first second-substrate side electrode having an edge, a transverse electric field being generated between the at least one first-substrate side electrode and the edge of the first second-substrate side electrode by application of voltage between the first-substrate side electrode and the first second-substrate side electrode; and a second dot region adjacent to the first dot region, the second dot region including a second second-substrate side electrode interposed between the second substrate and the liquid crystal layer, a second transmissive display region to perform transmissive display, and a second reflective display region to perform reflective display, the second second-substrate side electrode being separate and independent from the first second-substrate side electrode, the second second-substrate side electrode having an edge separated from the edge of the first second-substrate side electrode by a gap, a transverse electric field being generated between the first-substrate side electrode and the edge of the second second-substrate side electrode by application of voltage between the first-substrate side electrode and the second second-substrate side electrode, wherein at least one of 1) the first and second transmissive display regions are adjacent to each other or 2) the first and second reflective display regions are adjacent to each other, the liquid crystals of the liquid crystal layer aligning obliquely in reverse directions to each other by the transverse electric fields generated at the edges of the first and second second-substrate side electrodes.
