Abstract
An LCD device (20) includes a first substrate assembly (210), a second substrate assembly (250), a liquid crystal layer (230) having liquid crystal molecules interposed between the substrate assemblies, and alignment films (218, 258) disposed adjacent to the liquid crystal layer for making liquid crystal molecules of the liquid crystal layer align homogeneously. Each of pixel regions of the LCD device includes a reflection region and a transmission region. The LCD device further employs retardation films (261, 262, 263, 264) and compensation films (265, 266) for compensating for color in the reflection region and the transmission region of each pixel region, so as to ensure that the LCD device has a good quality display.
