ABSTRACT:
The invention provides a liquid crystal display device having a transmissive display region and a reflective display region in one dot region, and capable of obtaining a bright and high-contrast display in both a reflective display and a transmissive display. In particular, a liquid crystal display device according to the present invention can include a reflective display region and a transmissive display region provided in one dot region, and a reflection layer provided in the reflective display region. A pixel electrode, a TFT element for driving the pixel electrode, a capacitive electrode connected to the pixel electrode, an electrode part arranged to oppose the capacitive electrode via an insulating layer are formed in the dot region. Further, in the display regions within the dot region, the capacitive electrode or the capacitive line can be arranged at a position where it overlaps, in plan view, the inclined region between the reflective display region and the transflective display region.
