Abstract
A liquid crystal display device includes a substrate, a liquid crystal layer, a liquid crystal alignment layer between the substrate and the liquid crystal layer, a barrier layer between the liquid crystal alignment layer and the liquid crystal layer, and a gasket formed around the perimeter of the liquid crystal layer and abutting the barrier layer. The gasket has a width less than or equal to 400 micrometers. A second substrate also includes a liquid crystal alignment layer and a barrier layer formed over the liquid crystal alignment layer. The gasket also abuts the barrier layer of the second substrate. In a particular embodiment, the substrate is a reflective display backplane, and the second substrate is a transparent substrate having a transparent electrode layer. The gasket of the present invention is much narrower than gaskets of the prior art, which enables LCD devices to be made smaller and cheaper because more LCD devices can be produced per wafer.
