Light control film with turning film and lenticular diffuser for view enhancement in the horizontal plane

A lenticular diffuser, comprising:

• a substantially smooth surface, wherein the substantially smooth surface defines a display axis extending perpendicular to the substantially smooth surface;
• and
• a structured surface comprising a plurality of microstructures defining a plurality of substantially parallel grooves extending along a plane substantially perpendicular the display axis,
• wherein the structured surface comprises a plurality of microstructures each comprising a lenticular prism having linear end sections connected by a blend section separated by a substantially flat land area, wherein the blend section shape is a segment of an ellipse or 2nd, 4th or 6th order polynomial, and wherein the linear end sections comprise at least about 5% of the lenticular prism;
• wherein a cross section of each lenticular prism extends along a plane substantially parallel to the display axis in a direction from the substantially smooth surface to a vertex, and
• wherein the lenticular diffuser refracts light that is substantially collimated in a first plane toward a second plane substantially perpendicular to the first plane.
