Abstract

Disclosed is a liquid crystal display which does not have any spacer on a display electrode. If a spacer which consists of plastic or glass exists on a display electrode, a Reverse-Twist domain and/or Reverse -Tilt domain is induced into a pixel area by the spacer. Therefore, linearly polarized light cannot be rotated at the portion, and light leakage occurs at dark-state. Thus, contrast ratio is deteriorated. Although a spacer has a significant role of uniform cell gap control across the large area substrate in the liquid crystal display, the spacer should not exist on the display electrode from the reasons described above.
