    摘要： 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.

    摘要： There are provided a light source device and a display device which do not generate a wrinkle on an optical sheet even if the optical sheet is held on an LED substrate. A reflection sheet 11 is disposed between each of head portions possessed by a rivet, a positioning rivet and a support rivet and one surface of an LED substrate 8 where an LED is mounted, and a gap in a direction of a sheet thickness is provided between the head portion of each of the rivets and the reflection sheet 11. In the case in which a sudden thermal change is caused, therefore, the reflection sheet 11 expands or contracts between the head portion of each of the rivets and the reflection sheet 11 so that the wrinkle can be prevented from being generated over the reflection sheet 11.
