Abstract
AbstractA new non‐rubbing process suitable for active matrix LCDs has been developed. The process involves the formation of a silane‐based monolayer on the surface followed by UV irradiation. This leads to a photo‐dimerized alignment layer capable of giving a defect‐free alignment of nematic liquid crystals. The electro‐optic characteristics of LCDs fabricated using the photo‐dimerized layer are shown to be comparable to those with a rubbed polyimide alignment layer. In addition, the anchoring energies in the two cases are shown to be very similar making the new alignment layer technology attractive for applications.
