Abstract: A liquid crystal display includes a first substrate and a second substrate bonded to each other at their periphery by a sealant, with liquid crystal sealed between the first substrate and a second substrate, and has a display region. The first substrate is formed, between the sealant and an end portion of the display region, with a wall that partitions the liquid crystal into a portion on the display region side and a portion on the sealant side. A gap exists between the tip of the wall and the second substrate side. In the liquid crystal display device, a liquid crystal portion that has been contaminated is restrained from moving into the display region.

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.
