Abstract
In a substrate for a display apparatus, the substrate includes a base substrate and a shielding layer formed on a surface of the base substrate. The shielding layer has an energy bandgap corresponding to a reference wavelength of external light. Thus, the shielding layer blocks light having wavelength equal to or less than the reference wavelength, so that a wavelength band of light may be adjusted.

A substrate comprising:
- a base substrate;
- and
- a shielding layer formed on one surface of the base substrate to block an external light having a wavelength equal to or less than a reference wavelength and incident from an outside of the substrate,
- wherein the shielding layer has an energy bandgap of about 2.8 eV to about 3.2 eV.

A display apparatus comprising:
- a first display substrate comprising a first base substrate and a pixel unit formed on the first base substrate to receive a pixel voltage;
- a second display substrate coupled with the first display substrate while facing the first display substrate;
- and
- a color layer interposed between the first and second display substrates to display a color in response to the pixel voltage applied to the pixel unit,
- wherein the second display substrate comprises:
- a second base substrate facing the first base substrate;
- and
