Original Abstract Submitted

An optical construction includes a lens film having a structured first major surface having a plurality of microlenses and an opposing second major surface. A light absorbing layer is disposed on the second major surface and has an average thickness of greater than about 0.5 microns and an optical density of greater than about 3. A plurality of openings are provided in the light absorbing layer. A major surface of the light absorbing layer includes a plurality of irregular features imparting an average mean square height Sq of greater than about 0.05 microns. In a cross-section, the opening includes opposing first and second sidewalls having respective first and second best linear fits with respective r-squared values R1 and R2 and respective linear slope magnitudes S1 and S2, each of R1 and R2 greater than about 0.8. S1 and S2 within 30% of each other.
