A graphic surface display device comprises a graphic surface be displayed and a cover of substantially transparent material overlying and in optical contact with the graphic surface. The cover has a minutely textured outer surface such that the angle between a first vector normal to a randomly selected point on the cover\s surface; and, a second vector which passes through the selected point and which is normal to a plane tangential to the graphic surface at the point of intersection of the second vector with the graphic surface; has substantially unity probability of exceeding 45°.
