The present invention provides a manufacturing method of a security film for a display which comprises the following steps: a step for supplying a first film to a pattern formation roller (S10); a step for forming a first pattern unit in which at least more than two patterns having the cross section in a shape of an isosceles triangle with a right angle and a point facing the upward direction are successively arranged in parallel, on one surface of the first film using the pattern formation roller (S20); a step for supplying a second film to a slot die coater (S30); a step for laminating a second resin layer with a predetermined thickness on one side of a second film using the slot die coater (S40); and a step for forming a second pattern unit in which at least more than two patterns having the cross section in a shape of an isosceles triangle with a right angle and a point facing the downward direction to form a vertical symmetric shape with the first pattern are successively arranged in parallel, by closely attaching the second resin layer laminated on one side of the second film to the first pattern unit formed on one side of the first film (S50).
