PURPOSE: To prepare a highly transparent antistatic protective film which can be applied to various displays, esp. a liq. crystal display, hardly causes reflection of light due to the difference in refractive index of light at the interface of the film and a polarizing plate stuck to the film.

CONSTITUTION: This highly transparent and slightly sticky protective film is obtd. by forming an antistatic layer 2 on one side of a substrate film 1 made of a monoaxially oriented polyethylene terephthalate film and forming an acrylic self-adhesive layer 3 on the other side of the substrate film 1. The protective film may comprise the substrate film 1, an antistatic layer 2 formed on one side of the substrate film 1, and an acrylic self-adhesive layer 3 formed on the surface of the antistatic layer 2.
