Patent ID: 7030424

Claim:
A substrate comprising: a substrate body having a first surface and a second surface that is opposite to the first surface; a first thin film pattern formed on the first surface of the substrate body, the first thin film pattern including a first liquid crystal of which first liquid crystal molecules are arranged in a first direction in order to transmit only a first light having a first wavelength and a specific polarizing axis; a second thin film pattern formed on the first surface of the substrate body, the second thin film pattern including a second liquid crystal of which second liquid crystal molecules are arranged in the first direction in order to transmit only a second light having a second wavelength and the specific polarizing axis; and a third thin film pattern formed on the first surface of the substrate body, the third thin film pattern including a third liquid crystal of which third liquid crystal molecules are arranged in the first direction in order to transmit only a third light having a third wavelength and the specific polarizing axis.
