Abstract
A structure provides for encapsulating a color filter in a planarized protective coating, forming a transparent electrode on the planar surface of the protective coating and forming an orientation film over the transparent electrode wherein the orientation film extends beyond the boundary defined by the seal between the two substrates of a liquid crystal device. The seal itself can be attached at one of its ends to the orientation film, or it can be attached at one of its ends to a portion of the transparent electrode such that that end is surrounded by the abutting orientation film. In both of the seal attachment schemes the other end of the seal is attached directly to one of the substrates. Typically the substrates are glass substrates.
