Abstract
A method of making a phase difference film includes: (a) providing a substrate having a first surface provided with a light-shielding layer and a second surface provided with an orientable layer; (b) providing a first linear polarized UV light to irradiate the orientable layer and providing a second linear polarized UV light to irradiate the orientable layer so as to form the orientable layer into an alignment layer having first and second regions that are photo-oriented in two different orientation directions, respectively; and (c) coating a liquid crystal material on the alignment layer and curing the liquid crystal material.
