Filed: 1987-07-30
Abstract: PURPOSE:To easily and inexpensively determine the conditions for rubbing of an oriented film by evaluating the liquid crystal orientational capacity of the oriented film from the quantity of the transmitted light when straightly polarized light is projected on the surface of said film. CONSTITUTION:Helium-neon laser light 11 is projected perpendicularly on the surface of the oriented film 13 via a polarizing plate 12 (the axis of polarization direction is shown by an arrow) and while the film 13 is rotated each one degree, a change in the quantity of the transmitted light 14 is measured by a photocell 15. The measured orientation index S of the oriented film A is 0.004 when the max. quantity of the transmitted light is defined as Imax, the min. quantity of the transmitted light as Imin and the orientational capacity index S as S=(Imax-Imin)/(Imax+Imin). The S determined by the method similar to the method mentioned above with the film which is not subjected to the rubbing is <=0.001. Namely, the oriented film subjected to the rubbing treatment has the anisotropy of the transmittivity with the incident linearly polarized light. The degree of the rubbing treatment, i.e., the orientational capacity of the liquid crystal is known by determining the anisotropy of the light transmittivity.
