Abstract

An optical sheet (100) includes a base film (110), a plurality of prism patterns (120) and a plurality of first embossing patterns (130). The prism patterns (120) are formed on an upper surface of the base film (110). Each of the prism patterns (120) has the shape of a trigonal prism and includes a first inclined surface (122) and a second inclined surface (124). The first and second inclined surfaces (122,124) are inclined with respect to the upper surface of the base film (110) and meet each other at a peak portion (126). First embossing patterns (130) are formed at the peak portion (126).

Description

technical field [0001] The present invention relates to an optical sheet, a method of manufacturing the optical sheet, and a display device having the optical sheet. More particularly, the present invention relates to an optical sheet capable of improving optical characteristics of light incident into a display panel, a method of manufacturing the optical sheet, and a display device having the optical sheet. Background technique [0002] Liquid crystal display (LCD) devices that display images can be lighter and thinner than other types of display devices. Additionally, LCD devices can consume less power. Accordingly, LCD devices have been widely used in various fields. [0003] LCD devices do not generate light by themselves. Accordingly, an LCD device may utilize a light generating unit that provides light to a display panel of the LCD device. [0004] In notebook computers, monitors, etc., the light generating unit includes a lamp, a light guide plate, and an optical ...
