Abstract
A light management film includes a first layer with a thermoplastic resin and a particular phosphonium sulfonate salt, and a second layer formed from a curable composition and having a refractive index of at least 1.5. The light management film exhibits reduced static electricity build-up and reduced dust attraction, making it easier to handle during fabrication of display devices such as the flat panel displays of laptop computers.
