Optical Member, Method of Manufacturing the Optical Member and Backlight Assembly Having the Optical Member |
摘要 |
An optical member includes a base body, a plurality of light-concentrating lenses and a plurality of light-diffusing patterns. The base body has a first surface and a second surface which is opposite to the first surface and receives light from light sources. The light-concentrating lenses are formed on the first surface. The light-diffusing patterns are respectively formed at positions of the second surface respectively corresponding to the light sources to reduce an amount of light reflected by the light-concentrating lenses. Each of the light-diffusing patterns includes curved surfaces extending in a first direction and has a width which is in a predetermined range. The light-diffusing patterns are separated from one another in a second direction substantially perpendicular to the first direction.
