Abstract
A transparent glass substrate having an antiglare surface that minimizes sparkle. The antiglare surface has a roughened portion that surface that has a RMS amplitude of at least amplitude of at least about 80 nm. The antiglare surface may also include a portion that is unroughened, or flat. The fraction of the antiglare surface that is roughened is at least about 0.9, and the fraction of the surface that is unroughened is less than about 0.10. The antiglare surface has a pixel power deviation of less than about 7%.
