Patent ID: 7961280

Claim:
A semi-transmissive liquid crystal display device, comprising: an active matrix substrate and a counter substrate which are provided so as to face each other; and a liquid crystal layer provided between the active matrix substrate and the counter substrate, wherein a plurality of pixels each having a reflective region for providing reflection mode display and a transmissive region for providing transmission mode display are arranged in a matrix pattern, the active matrix substrate includes a plurality of source lines extending in parallel with each other between the pixels, a first transparent electrode provided in each pixel and connected to each source line through a switching element, an insulating layer provided on the first transparent electrode and having an opening in each pixel, a reflective electrode provided in each pixel on the insulating layer and connected to the first transparent electrode through the opening, and a second transparent electrode provided in each pixel, overlapping the reflective electrode and an exposed region of the first transparent electrode from the reflective electrode, and connected to the reflective electrode and the first transparent electrode, a region where the reflective electrode is formed and the exposed region of the first transparent electrode from the reflective electrode form the reflective region and the transmissive region, respectively, and respective outer peripheral ends of the reflective electrode and the second transparent electrode are aligned with each other in each pixel.
