Substrate, method of manufacturing the same and display apparatus having the same

A method of manufacturing a substrate, comprising:

• forming a first thin film pattern on a first surface of a 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;
• forming a second thin film pattern 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
• forming a third thin film pattern 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.

A display apparatus comprises:

• a first substrate including a first surface and a second surface that is opposite to the first surface;
• a second substrate including a third surface facing the first surface, and a fourth surface that is opposite to the third surface;
• a polarization-color filter pattern including i) a first thin film pattern formed on the first surface of the first substrate, the first thin film pattern including 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 first polarizing axis, ii) a second thin film pattern formed on the first surface of the first substrate, 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 first polarizing axis, and iii) a third thin film pattern formed on the first surface of the first substrate, 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 second wavelength and the first polarizing axis;
• an electric field generating part disposed between the first and second substrates, the electric field generating part generating electric fields between the first and second substrates;
• a liquid crystal layer disposed between the first and second substrates, an arrangement of liquid crystal molecules of the liquid crystal layer being changed by the electric fields to adjust an optical transmittance;
• and
• a polarizing plate disposed on the second substrate, the polarizing plate having a second polarizing axis.
