An apparatus and method is provided for preventing smudges ( 608 ) including oils and dust from collecting on a portable electronic device display ( 110, 150, 200, 300 ). A plurality of islands ( 606 ) are formed on a surface of the display device, each island ( 606 ) comprising a transparent material and having a diameter of between 5 and 200 nanometers. Liquid ( 608 ) forming on the plurality of islands has a large contact angle ( 610 ), increasing the likelihood of the liquid migrating from the display device and thereby removing contaminants therewith.
