Liquid crystal display device with different pretilt angles of liquid crystal layer adjacent two substrates

A liquid crystal display device, comprising:

• a first substrate and a second substrate;
• a liquid crystal layer having liquid crystal molecules interposed between the first and second substrates, wherein a pretilt angle of the liquid crystal layer adjacent to one of the substrates is in a range of 0° to 15°, and a pretilt angle of the liquid crystal layer adjacent to the other substrate is in a range of 75° to 90°;
• a first upper retardation film disposed at an outer surface of the first substrate, the first upper retardation film being a quarter-wave plate;
• a common electrode disposed at an inner surface of the first substrate;
• a pixel electrode disposed at an inner surface of the second substrate;
• a plurality of pixel regions, each of the pixel regions including a reflection region and a transmission region;
• and
• a first lower retardation film disposed at an outer surface of the first substrate, the first lower retardation film being a quarter-wave plate.
