Abstract: A light shielding net, which can improve productivity by facilitating a weaving process, can be wound by a winding device due to a high winding strength, and can express various colors, thereby adjusting a light shielding amount and improving a design aesthetic sense. To this end, a warp yarn is made of a PE monofilament, the weft yarn is made of a PE film, and the two warp yarns are repeatedly woven in a Leno weave form surrounding each weft yarn.
