LCD SUBSTRATE WITH PROTRUSIONS AND METHOD OF MAKING

摘要

A first liquid crystal display (LCD) substrate includes protrusions for holding a second substrate spaced apart from the first substrate. The protrusions may be posts which are located in gaps between adjacent pairs of electrodes on the first substrate, and are configured to contact the second substrate in gaps between adjacent pairs of electrodes on the second substrate. The protrusions may be posts or ridges that have a shape, such as a tapered shape, with surface area for contacting the second substrate which is smaller that a cross-sectional area away from distal ends of the protrusions. The first substrate may include an opaque material throughout or in a layer of the substrate. Electrodes on the first substrate element may be formed from an opaque material. The substrate element may include a sputtered alignment barrier layer.
