Abstract
Official abstract text for this publication.
A display device includes a display panel, a light guide plate (LGP), a light source, and a positioning component. The LGP is disposed on a display surface of the display panel and has an upper surface and a lower surface opposite to each other, a light-incident surface, a first light-guiding block, and a second light-guiding block. A display area of the display panel corresponds to the first light-guiding block. The second light-guiding block extends outside the display area and has at least one recess portion. The recess portion is located on at least one of the upper surface and the lower surface and extends to the light-incident surface. The light source is disposed beside the light-incident surface. The positioning component is disposed on the second light-guiding block and located in the recess portion. Besides, the positioning component extends outside the recess portion and fixes the location of the light source.
