摘要： The present invention relates to an optical film having improved optical performance and to a backlight unit comprising the same. More particularly, the present invention relates to a microlens array (MLA) sheet which comprises a base unit and a lens unit formed on one side of the base unit, wherein the lens unit consists of a plurality of conical lenses. Existing hemispherical microlens array sheets have limitations in terms of improving luminance, and therefore cannot replace prism sheets in high luminance products. However, the microlens array sheet consisting of conical lenses of the present invention can improve both luminance and viewing angle characteristics.

摘要： There is provided a Fresnel lens structure including: a Fresnel lens layer; and a planarization layer disposed on the Fresnel lens layer, any one of the Fresnel lens layer and the planarization layer being formed of a birefringent material and the other being formed of an isotropic material having a refractive index equal to a highest refractive index or a lowest refractive index of the birefringent material. In the Fresnel lens structure, a 2/3D image switching structure is simplified and switching thereof is easy. 2/3D switching can be performed without using an apparatus with complicated structure, whereby a stereoscopic image display apparatus structure may be simplified and manufacturing costs may be reduced as compared with a lenticular lens by using a Fresnel shaped lens structure.

摘要： There is provided an optical film for backlight units or illuminators. The optical film comprises a light-incident portion and a light exit portion. Here, the optical film is characterized in that it comprises a plurality of protrusions formed on at least one of the light-incident portion and the light exit portion, wherein a plurality of the protrusions satisfies the requirements of the following Equation: 80×H1/3≦P≦200×H1/3 and 0.I×D≦H≦D, provided that a mean diameter of protrusions is represented by ‘D’, a mean height of protrusions is represented by 1H′, and a mean distance between adjacent protrusions is represented by ‘P’. Therefore, the optical film may be useful to suppress blocking between films and the formation of surface defects, which are caused by the Moire, Newton ring and wet-out phenomena, without degrading the brightness.
