OPTICAL SHEET AND OPTICAL DISPLAY DEVICE COMPRISING SAME

摘要

An optical sheet of the present invention comprises: a protective part which includes a light incident surface and a light emission surface facing the light incident surface; an optical pattern layer formed on the light incident surface; and a polarizer formed on the light emission surface, wherein the light incident on the light incident surface forms an angle (θ1) of about 50 ° to about 85 ° with respect to the normal of the light incident surface, the light emitted from the light emission surface forms an angle (θ2) of about ± 30 ° or more with respect to the normal of the light emission surface, and the luminance at the emission angle of the side-lobe is 10% or less of the luminance emitted in the normal direction of the light emission surface.
