Abstract
A display device that includes a display panel, a multilayer light guide plate structure, and a light source is provided. The display panel has a display surface. The multilayer light guide plate structure is located on the display surface of the display panel. The multilayer light guide plate structure has a light incident surface, an upper surface, and a lower surface opposite to the upper surface, and the multilayer light guide plate structure includes a plurality of light guide plate layers stacked together. The light source is located beside the light incident surface of the multilayer light guide plate structure and has a light emitting surface. A multilayer light guide plate structure and a front light module are also provided.
Claims23
