Figure 11. Polar diagrams of absorbances measured from LC cells fabricated with 6F-HAB-
ETCOU films which were treated by 0 ° ( θ )- and 90 ° ( θ )-exposure protocols in Table 1. Here, θ is de-
fined as the angle between the longer axis of the glass slide and the electric vector of the linearly po-
larized actinic UV light (260-380 nm wavelength). 0.50 J/cm 2 per exposure was employed.
