Liquid crystal display device

A manufacturing process of a liquid crystal display device, the liquid crystal display device comprising:

• a first substrate with a smooth orientation film surface;
• a second substrate with an orientation film surface less smooth than the first substrate;
• and
• a liquid crystal layer sandwiched between the first substrate and the second substrate, the liquid crystal layer having super twisted nematic liquid crystal whose twist angle is not less than 250.degree.,
• wherein pretilt angles of the liquid crystal molecules close to the first substrate are not less than 4.degree., and great enough to obtain required anchoring energy, and
• pretilt angles of the liquid crystal molecules close to the second substrate are smaller than the pretilt angles of the liquid crystal molecules close to the first substrate,
• the manufacturing process of the liquid crystal display device, comprising a step for baking a material of the orientation film on the second substrate at a lower temperature than a material of the orientation film on the first substrate so that the pretilt angles of the liquid crystal molecules close to the second substrate are smaller than the pretilt angles of the liquid crystal molecules close to the first substrate.
