ABSTRACT:
An alignment structure provided in a twisted nematic field effect mode (TN-FEM) liquid crystal display includes, a first insulating layer deposited substantially along the normal direction of one of the supports, a second insulating layer deposited on said first insulating layer in a direction slant to the normal direction of the support, and a third insulating layer deposited on the second insulating layer slant to a direction rotated ninety degrees from said direction while the normal line of the support serves as the rotation axis thereof, thereby providing a three-layer alignment structure.
