Abstract
An LCD device (100) includes a first substrate (110), a second substrate (120), and a liquid crystal layer (130) having liquid crystal molecules interposed between the first and second substrates. A pixel electrode (112) is disposed at an inner surface of the first substrate, and a common electrode (122) is disposed at an inner surface of the second substrate. A storage capacitor (140) has an upper storage electrode (118) and a lower storage electrode (113) disposed at an inner surface of the first substrate, with the upper storage electrode electrically connecting with the pixel electrode. The upper storage electrode functions as a reflection electrode. This structure ensures the LCD device is capable of providing a display both in a reflection mode and a transmission mode.
