Abstract
Each pixel includes first through fourth liquid crystal domains. The first through fourth liquid crystal domains are arranged in this order along the pixel longitudinal direction. The reference alignment direction of the second liquid crystal domain and the reference alignment direction of the third liquid crystal domain are respectively essentially the 135° direction and essentially the 315° direction, or respectively essentially the 45° direction and essentially the 225° direction. The pixel electrode includes a first through fourth slitted regions corresponding to the first through fourth liquid crystal domains, and a boundary region located between the second and third slitted regions. The boundary region includes n boundary slits (where n≥3) extending essentially in parallel to the pixel transverse direction; (n-1) first bridging portions each located between two adjacent boundary slits; and (n-2) dent patterns each located between two adjacent first bridging portions.
