An antistatic film comprising:
- a substrate;
- a lower coating layer positioned on the substrate and consisting of a conductive material, tetraethyl orthosilicate (TEOS), and silsesquioxane (SSQ);
- and
- an upper coating layer positioned on the lower coating layer and consisting of the conductive material and tetraethyl orthosilicate,
- wherein the conductive material in the lower coating layer as the conductive material in the upper coating layer are a same material and the conductive material in the lower coating layer has a higher parts by weight than that in the upper coating layer, based on 100 parts by weight of the lower and the upper coating layer on the substrate, respectively.
