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.

First claim

What is claimed is:

1. A method of making a phase difference film, comprising:
(a) providing a first light-transmissible substrate having opposite first and second surfaces, the first surface being formed with a patterned light-shielding layer thereon, the second surface being formed with an orientable layer of a photo-orientable material thereon;
(b) providing a first linear polarized UV light that is directed from one side of the first light-transmissible substrate, at which t…
