  • Patent number: 11126286
    Abstract: A method of fabricating a window deco film includes forming a hard coating layer, forming a deco layer on the hard coating layer, forming a light-shielding layer on the deco layer, and forming an acryl-based coating layer on the hard coating layer before forming the deco layer, or on the light-shielding layer. The window deco film may have a remarkably reduced thickness, and thus an entire thickness of an image display device including a window substrate to which the window deco film is applied may be also reduced. Additionally, even when the window deco film is attached to a curved window substrate, a bubble may not be generated at a curved portion of the window substrate. A mura caused by a retardation or a phase difference due to the window deco film may be suppressed. Thus, the window deco film may have an improved transmittance.
