The present invention relates to a security screen and a manufacturing method thereof. The security screen comprises: a first film layer; and a blind layer in which shielding partition walls for blocking input images are repeatedly arranged at a distance from each other in parallel or in a lattice configuration at a predetermined angle. The shielding partition walls are constituted by repeatedly printing or transferring a light-absorbing color ink onto one or both surfaces of the first film layer. The security screen is fitted to the displays of image devices such as computer monitors, cash dispensers, navigation devices, mobile phones and PDAs or is fitted to the glass of buildings or the like, thereby making it impossible for the image being output on the display to be viewed by any third party positioned on the left, right, above or below who is not the user of the image device, and which makes the image clearer by preventing the phenomenon of blurring and the phenomenon of glare which occur, for example, when external light shines on devices and on glass or the like.
