Abstract
A window includes a base layer, a plurality of nitride layers disposed on the base layer, a plurality of oxide layers disposed on the base layer, and a protective layer disposed on the nitride layers and the oxide layers. The nitride layers are alternately stacked with the oxide layers on the base layer, and a sum of thicknesses of the nitride layers and thicknesses of the oxide layers is equal to or greater than about 500 nm and equal to or smaller than about 900 nm.
Claims15
A window, comprising:
