Abstract
A liquid crystal display device that includes a plurality of pixels, a first substrate and a second substrate, as well as a liquid crystal layer provided between the first and second substrates. A first alignment structure and a second alignment structure are formed on the first substrate, and a third alignment structure and a fourth alignment structure are formed on the second substrate, for controlling an alignment of the liquid crystal. At least one auxiliary alignment structure is also formed on the first substrate for controlling an alignment of liquid crystals. The first and second alignment structures extend linearly in different directions from each other in a pixel, and the third and fourth alignment structures extend parallel to the first and second alignment structures, respectively. Also, the auxiliary alignment structure extends substantially along an edge of the pixel.
