1. A liquid crystal display device comprising:

  • a first substrate;

    a second substrate facing said first substrate;

    a liquid crystal layer sealed between said first substrate and said second substrate;

    a first electrode formed on said first substrate;

    a second electrode formed on said second substrate;

    a first molecule orientation film formed on said first substrate so as to cover said first electrode;

    a second molecule orientation film formed on said second substrate so as to cover said second electrode;

    a first polarizing plate provided outside of said first substrate; and

    a second polarizing plate provided outside of said second substrate in a crossed Nicol state to said first polarizing plate,wherein;

    in a non-driving state in which a driving voltage is not applied between said first electrode and said second electrode, liquid crystal molecules are oriented in a vertical direction to said first substrate and said second substrate by said first molecule orientation film and said second molecule orientation film, respectively;

    on said first substrate, a structural pattern is formed so as to extend in a first direction parallel to a surface of said liquid crystal layer and so as to form, in a driving state in which a driving voltage is applied between said first electrode and said second electrode, an electric field periodically changing in a second direction that is parallel to said liquid crystal layer and vertical to said first direction; and

    said liquid crystal molecules substantially tilt in said first direction in said driving state.
