| description | A light guide plate including a light guide main body and an index matching layer is provided. The light guide main body has a light-emitting surface and a bottom surface opposite to the light-emitting surface. The index matching layer is disposed adjacent to the bottom surface, wherein a refractive index of the light guide main body is n1, and a refractive index of the index matching layer is n2. 1.07*n2≤n1≤1.7*n2, and 0.1≤(n1−n2)≤0.7. A thickness of the index matching layer is larger than 500 nm. A backlight module and a display apparatus are also provided. |
