    Abstract: The present invention discloses an optical assembly used in the backlight module. The optical assembly comprises: a first optical film having a first surface; an adhesive layer having a second surface and a third surface opposite to the second surface, wherein the second surface of the adhesive layer is disposed on the first surface of the first optical film; and a diffusing sheet having a fourth surface comprising a plurality of first microstructures and a plurality of second microstructures, wherein each of the plurality of second microstructures extends along a first direction, wherein the maximum height of the plurality of second microstructures is greater than that of the plurality of first microstructures so as to bond the plurality of second microstructures to the third surface of the adhesive layer.

    Abstract: The present invention discloses an optical assembly. The optical assembly comprises: a first optical film having a first surface; an adhesive layer having a second surface and a third surface opposite to the second surface, wherein the second surface of the adhesive layer is disposed on the first surface of the first optical film, wherein the adhesive layer comprises a thermally-curable material having a plurality of first acrylate functional groups; and a second optical film comprising a plurality of microstructures, wherein each of at least one of the plurality of microstructures has a top planar surface having a plurality of second acrylate functional groups, wherein the top planar surface is boned to the third surface of the adhesive layer by the bonding between the plurality of first acrylate functional groups and the plurality of second acrylate functional groups formed in an illumination process while the thermally-curable material of the adhesive layer has been thermally-cured for preventing the top planar surface from penetrating into the adhesive layer.
