<p>PURPOSE:To obtain an oriented film having high bonding strength to its polymer film substrate and capable of controlling the orientation of a liq. crystal such as the vertical orientation or the orientation under the control of the tilt angle by using a specified organosilicon compound. CONSTITUTION:A soln. of an organosilicon compound represented by general formula 1 is coated on a polymer film substrate, especially a polyethylene terephthalate film substrate after forming a transparent electrode on the substrate. In the formula Y, is vinyl, epoxy or methacryloxy for providing high bonding strength to the polyethylene terephthalate film substrate, each of X1 and X2 is a hydrolyzable group sach as alkoxy, and R is phenyl in case of horizontal orientation and alkyl in case of vertical orientation. The coated film is stabilized by heat treatment and rubbed with cotton cloth or the like in case of horizontal orientation or orientation under the control of tilt angle.</p> |
