A mixture of two polyamic acids, one having an alkyl side chain and ordinarily used for
vertical liquid crystal alignment and the other without a side chain and ordinarily used for …

We proposed a method to control the pretilt angle of liquid crystals by stacking of a vertical
alignment layer on a planar alignment layer. The pretilt angle can be controlled over the full …

We demonstrate a new approach to control the pretilt angle of liquid crystals (LCs) with
photocurable prepolymer in a cell fabricated with vertically aligned substrates. During UV …

High-quality alignment of liquid crystals (LCs) for large area display has been highly
demanding for display market. To achieve a uniform and stable LC alignment, a …

Doping a minute amount of photocurable monomers in a liquid crystal (LC) cell, we can
stabilize the LC alignment after UV exposure by forming a LC pretilt layer on the substrate …

Two substrates were coated with a mixture containing two polyamic acids. One of the
polyamic acids has an alkyl side chain and ordinarily is used for vertical liquid crystal …

Polyimide films were used for liquid crystal (LC) alignment layers to control LC pretilt angles
over the full range (8°–90°). The pretilt angles could be controlled using polyimide films …

The vertical alignment of liquid crystal (LC) on an inorganic silicon oxide layer, which is
fabricated by a simple photoinduced transformation process of an ultrathin poly …

A new photoalignment method of controlling the pretilt angle of liquid crystals (LCs) by using
organic/inorganic hybrid interpenetrating polymer networks (IPNs) is proposed and …

Background: The alignment of liquid crystals by surfaces is crucial for applications. It
determines the director configuration in the bulk, its stability against defects and electro …
