A printing plate and a method of fabricating an LCD device are disclosed. The printing plate includes convex and concave portions, and a blanket support formed in the concave portion to prevent the bottom of the concave portion from being directly in contact with a pattern material coated on a blanket of a printing roll. The blanket support is additionally formed in the concave portion of the printing plate to prevent the pattern material coated on the blanket of the printing roll from being directly in contact with the bottom of the concave portion. In this case, the pattern material can be prevented from being transferred onto the printing plate in an undesired pattern. As a result, it is possible to form a precise pattern.
