Abstract
Disclosed are a transflective liquid crystal display device and a driving method thereof. The transflective liquid crystal display device includes: a first surface electrode (), a first pixel electrode (), a second surface electrode () and a second pixel electrode () located in transmissive regions (A); the first surface electrode () and first pixel electrode () are located between a first substrate () and a liquid crystal layer (), the second surface electrodes () and the second pixel electrodes () are located between a second substrate () and the liquid crystal layer (). The device further includes: a third surface electrode (), a reflection layer () and a third pixel electrode () located in reflective regions (B); the third surface electrode (), the reflection layer () and the third pixel electrode () are located between the first substrate () and the liquid crystal layer (). The liquid crystal layer () in both the transmissive region (A) and the reflective region (B) of the display device have an equal thickness, thereby drastically reducing the process difficulty of the device while guaranteeing the same phase retardations in both transmissive region and reflective region.
