Abstract
To provide a transflective liquid crystal display device capable of obtaining a display with high brightness, high contrast, and wide viewing angle, a liquid crystal display device including a liquid crystal layer sandwiched between a pair of substrates, the liquid crystal layer having liquid crystal having negative dielectric anisotropy whose initial alignment state exhibits a vertical alignment; and a plurality of dot regions arranged in an image display region, each of the dot regions being provided with a transmissive display region to perform transmissive display and a reflective display region to perform reflective display therein, the transmissive display regions or the reflective display regions of two adjacent dot regions P1, P2 provided at positions facing edges of the respective dot regions and the liquid crystal aligned obliquely in reverse directions to each other by a transverse electric field which is generated at each edge when a voltage is applied.
