Abstract
Each pixel of the liquid crystal display device includes a first, second, third, and fourth domains arranged in two rows and two columns, and reference alignment directions of the respective domains are first, second, third, and fourth directions. The first direction and the second direction form an angle of approximately 180°, and the first domain and the second domain are adjacent to each other in an oblique direction. The pixel electrode includes a plurality of first slits formed in a region corresponding to the first domain and extending approximately parallel to the first direction, and a plurality of second slits formed in a region corresponding to the second domain and extending approximately parallel to the second direction, and has no slits in a region corresponding to the third domain and no slits in a region corresponding to the fourth domain.
