Liquid crystal display device

A liquid crystal display device, comprising:

• a first substrate including a first main pixel electrode and a second main pixel electrode electrically connected each other extending along a first direction, respectively,
• a second substrate including a first main common electrode, a second main common electrode, and a third main common electrode electrically connected each other extending along the first direction, respectively, and the first main pixel electrode being arranged between the first main common electrode and the second main common electrode so as to obliquely face the first and second main common electrodes, and the second main pixel electrode being arranged between the second main common electrode and the third main common electrode so as to obliquely face the second and third main common electrodes;
• and
• a liquid crystal layer having liquid crystal molecules and held between the first substrate and the second substrate;
• wherein among a first inter-electrode distance between the first main common electrode and the first main pixel electrode, a second inter-electrode distance between the second main common electrode and the first main pixel electrode, a third inter-electrode distance between the second main common electrode and the second main pixel electrode, and a fourth inter-electrode distance between the third main common electrode and the second main pixel electrodes in a second direction that intersects perpendicularly the first direction, respectively, one of the four inter-electrode distances is set to an optimal inter-electrode distance, and one of the four inter-electrode distances is different from at least one of the other three inter-electrode distances,
• herein, the optimal inter-electrode distance is defined as follows:
• in a range of voltage which is applied between the main pixel electrodes and the main common electrodes, more than 90% of a peak transmissivity is obtained by the optimal inter-electrode distance.
