Abstract

An LCD device (20) includes a first substrate (210) and a second substrate (250), a liquid crystal layer (230) interposed between the substrates. Each pixel regions of the LCD device includes a reflection region and a transmission region. A pre-tilt angle of liquid crystal molecules adjacent to one of the substrates is in a range of 0° to 15°, and a pre-tilt angle of liquid crystal molecules adjacent to another substrate is in a range of 75° to 90°. This structure ensures the LCD device has a fast response time.
