Abstract
A reflective-transmissive liquid crystal display (LCD) device with an improved display quality is achieved by forming a reflective area and a transmissive area having a cell gap greater than greater than that of the reflective area. A liquid crystal layer is disposed in a liquid crystal cell between the first and second substrates. The liquid crystal molecules are normally aligned at an angle equal to greater than about 45° with respect to a line parallel to the first substrate. The LCD device operates in a normally black mode.
