Abstract
A plasma addressed liquid crystal display and manufacturing method thereof is disclosed whose plasma addressing unit has a barrier of a predetermined height between a planar orientation layer and a rear substrate, a second electrode placed in the middle or on the top of the barrier, and a first electrode positioned between the barriers. The electrodes are made of metal paste which enables the use of a screen printing method, thereby facilitating manufacturing and allowing for a large screen display.
