ABSTRACT:
Aspects of the invention provide a transflective liquid crystal display device that prevents display failure, such as an afterimage and unevenness like stains, and achieves a bright display with a wide viewing angle in both transmissive display and reflective display. The liquid crystal display device of the invention is a vertically-aligned transflective liquid crystal display device having a multigap structure. Each pixel can include, in a dot region, a plurality of islands, and connecting portions for electrically connecting the adjoining islands. Two islands, of the islands, can be disposed in a transmissive display region, and the remaining island is disposed in a reflective display region. A boundary sloping area in which the thickness of a liquid crystal layer continuously changes is disposed right below the connecting portion in the pixel electrode.
