Abstract
An optical element and a display device incorporating the optical element are provided. The optical element comprises a panel member having a first surface and a second surface opposite to the first surface, and a jetted pattern of light extracting dots applied to the first surface. Each light extracting dot has a part-spherical surface intersecting the first surface and a transition between the part-spherical surface and the first surface. The transition includes substantially continuous angular configuration from the part-spherical surface angular orientation to the first surface angular orientation.
