    Abstract: Light directing films have a surface comprising a plurality of microstructures with peaks extending along a length of the surface. Each microstructure includes a plurality of elevated portions and a plurality of non-elevated portions. A void diameter, D?c#191, of the largest circle that can be overlaid on the surface of the light directing film without including at least a portion of an elevated portion is less than about 0.5 mm. The light directing film cannot be divided into a plurality of same size and shape grid cells forming a continuous two-dimensional grid, where each of at least 90% of the grid cells comprise either a single leading edge of an elevated portion, or a portion of an elevated portion where the elevated portion has a length that is greater than the average length of the elevated portions.

    Abstract: Light directing film (100) is disclosed. The light directing film includes a structured major surface (110) that includes a plurality of microstructures (150) extending along a first direction (142) and a plurality of elevated portions (160) disposed on the plurality of microstructures. The number density of the elevated portions across the light directing film is D. Each elevated portion includes a leading edge (162) and a trailing edge (164) along the first direction. The light directing film can be divided into a plurality of same size and shape grid cells that form a continuous two-dimensional grid. The area of each grid cell is approximately 1/D. Each of at least 70% of the grid cells includes a single leading edge (162) of an elevated portion (160).
