Abstract:
A liquid crystal display device with an in-plane switching mode, comprising:a first substrate having a first electrode and a second electrode formed thereon, the first electrode being arranged parallel to the second electrode, a first electric field being generated between the first electrode and the second electrode when a voltage is applied to the first and second electrodes;a second substrate having a third electrode and a fourth electrode formed thereon and disposed opposite to the first substrate, the third electrode being arranged parallel to the fourth electrode, a second electric field being generated between the third and fourth electrodes, the direction of the second electric field being substantially orthogonal to that of the first electric field; anda liquid crystal layer having liquid crystal molecules interposed between the first substrate and the second substrate such that, in an absence of said first and second electric fields, the liquid crystal molecules are arranged homogeneously with the first and second substrates and, in a presence of the first and second electric fields, major axes of said liquid crystal molecules adjacent to the first and second substrates are parallel to said first and second electric fields, respectively, and wherein said liquid crystal molecules are twisted relative to each other while remaining parallel to said first and second substrates in the presence of said first and second electric fields.
