Embodiment Construction

[0022] Reference will now be made to detailed embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0023] The optical film includes a reflective polarizing film, a first primer layer on the reflective polarizer film, and first protrusions on the first primer layer.

[0024] The optical film may also include a second undercoat layer underlying the reflective polarizing film, the second undercoat layer having a thickness substantially in the range between 5 nm and 300 nm.

[0025] The optical film can also include a protective layer on the reflective polarizing layer.

[0026] The thickness of the first undercoat layer is substantially in the range between 5 nm and 300 nm.

[0027] The first protrusion may be at least one of a microlens array, a lenticular lens array, a diffuser unit, and a prism unit.

[0028] The first protrusion may include a plurality of beads.

[0029] The reflective polarizing film may include first and second ...

Abstract

An optical film and a liquid crystal display including the optical film are disclosed. The optical film includes a reflective polarizing film, a first primer layer on the reflective polarizing film, and a first projection on the first primer layer.

Description

technical field [0001] Exemplary embodiments relate to an optical film including a reflective polarizing film and a liquid crystal display including the same. Background technique [0002] Recently, the display field that converts information of a plurality of electrical signals into visual information has been rapidly developed. Thus, a flat panel display device having excellent properties such as thin film, very light weight, and low power consumption has been introduced. Flat panel display devices have rapidly replaced existing cathode ray tubes and gained attention. [0003] Examples of flat panel display devices may include liquid crystal displays (LCDs), plasma display panels (PDPs), field emission displays (FEDs), and electroluminescence displays (ELDs). Since the liquid crystal display has a high contrast ratio and excellent performance to display moving pictures, the liquid crystal display is rapidly used in display screens of notebooks, monitors, and televisions....
