[0064] It can be understood that, the structure of the first adhesion layer 32 in this embodiment can be matched with any embodiment of the present invention. For example, if the structure of the first adhesive layer 32 of this embodiment is matched with the first embodiment of the present invention, then in the first embodiment, refer to Figure 4 , the first adhesion layer 32 of the first embodiment ( Figure 5 ) and the first dots 33 are also located on the first surface 311 of the light guide plate body 31, while the second adhesion layer 321 and the second dots 331 originally located on the second surface 313 of the light guide plate body 31 replace the cost embodiment The first adhesion layer 32 ( Figure 7 ), which has multiple graph structures. In other words, the structure of the first adhesive layer 32 of this embodiment can be an adhesive layer on any side of the light guide plate body 31 and be matched with any embodiment of the present invention or this embodime...

Abstract

The invention relates to a light-emitting device which comprises a light guide panel and at least one light source, wherein the light guide panel comprises a light guide panel body and at least one first adhesion layer; the first surface of the light guide panel body has a first surface area; each first adhesion layer is positioned on the first surface and has a first adhesion layer surface area, and the sum of the first adhesion layer surface areas is greater than 50% of the first surface area; and the light sources faces the light guide panel body and is used for generating light rays. Thus, the light emitting uniformity of the first surface can be improved.

Description

technical field [0001] The invention relates to a light-emitting device, in particular to a light-emitting device with a sheet-shaped adhesive layer on a light guide plate. Background technique [0002] refer to figure 1 , which shows a perspective view of a conventional backlight module. The backlight module 1 includes a plurality of light sources 11 and a light guide plate 12 . The light source 11 is used to provide light. The light guide plate 12 includes a light emitting surface 121 , a bottom surface 122 and a light incident surface 123 . The bottom surface 122 is opposite to the light-emitting surface 121 . The light incident surface 123 is located between the light emitting surface 121 and the bottom surface 122 and adjacent to the light emitting surface 121 and the bottom surface 122 . The light incident surface 123 is a flat surface for receiving light from the light source 11 . [0003] refer to figure 2 , which shows the figure 1 top view diagram. Since ...
