A cover window includes a base layer; a first coating layer on the base layer; and a second coating layer on the first coating layer. The first coating layer directly contacts a first part of an upper surface of the base layer and exposes a second part of the upper surface of the base layer, the upper surface of the base layer consists of the first part and the second part, and the second coating layer directly contacts the second part of the upper surface of the base layer exposed by the first coating layer, and an upper surface of the first coating layer.

Cover window, method of manufacturing cover window, and display device

A method of manufacturing a window includes preparing a base material layer, forming a first hard coating layer on the base material layer, and forming a second hard coating layer on the first hard coating layer. The forming of the second hard coating layer is performed in an environment having an oxygen concentration of about 0.01% to about 0.1%.
