摘要： In one embodiment, a first substrate is provided with first and second main pixel electrodes electrically connected each other extending along a first direction, respectively. A second substrate includes first to third main common electrodes electrically connected each other extending along the first direction, respectively. The first main pixel electrode is arranged between the first and second main common electrodes, and the second main pixel electrode is arranged between the second and third main common electrodes. Four inter-electrode distances are formed. 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 electrodes, more than 90% of a peak transmissivity is obtained by the optimal inter-electrode distance.
