    Abstract: Light directing film is disclosed. The light directing film includes a first structured major surface and an opposing second major surface. The first structured major surface includes a plurality of unitary discrete structures. Each unitary discrete structure includes a light directing portion that is primarily for directing light and includes a plurality of first side facets. Each first side facet makes an angle with the plane of the light directing film in a range from about 35 degrees to about 55 degrees. Each light directing portion also includes a first base that is defined by the plurality of first side facets and has a first minimum dimension. Each light directing portion also has a first maximum height. Each unitary discrete structure also includes a bonding portion that is primarily for bonding the light directing film to a surface. The bonding portion is disposed on and between the plurality of first side facets and includes a plurality of second side facets. Each second side facet makes an angle with the plane of the light directing film greater than about 70 degrees. The bonding portion also includes a second base that is defined by the plurality of second side facets and has a second minimum dimension less than about 10% of the first minimum dimension. The bonding portion also has a second maximum height. The ratio of the second maximum height to the second minimum dimension is at least about 1.5.

    Abstract: An optical system includes a reflective polarizer (20), and a display (10), first mirror (30a), and second mirror (30b) disposed on a same side of the reflective polarizer (20). The reflective polarizer (20) transmits an image emitted by the display (10) after the image is reflected by the first and second mirrors (30a, 30b). A mid-plane defined by intersection points between an optical axis of the system and the display (10), reflective polarizer (20), and second mirror (30b) has one-pass through four-pass regions having respective areas, A1 through A4. The one-pass region includes portions of the emitted image rays (15) that pass at least one time across the one-pass region, the two-pass region includes portions of the image rays (15) that pass at least two times across the two-pass region, the three-pass region includes portions of the image rays (15) that pass at least three times across the three-pass region, and the four-pass region includes portions of the image rays (15) that pass four times across the four-pass region, such that the ratio A4/A3 is between approximately 0.15 and approximately 0.40.
