Abstract
Provided is a light unit including a plurality of LED light sources formed on a PCB, a resin layer stacked on the PCB to diffuse and guide emitted light forwards, and a diffusion plate having an optical pattern printed thereon to shield light emitted from the LED light sources. The optical pattern is composed of a diffusion pattern implemented as at least one layer, or a combination of the diffusion pattern layer and a light shielding pattern. The light unit forms an optical pattern for shielding or diffusing light on a surface of a light diffusion plate of the back-light unit, and combines a diffusion pattern and a metal pattern to attain uniformity of light and realize a yellow-light shielding effect, thus leading to a reliable light quality.
