The above and other objects, features, and advantages of the present invention will become more fully understood from [Embodiment] Embodiment 2 FIG. 1 is a side view showing a surface light source according to a first embodiment of the present invention. Referring to FIG. 1, the surface light source 100 of the present embodiment includes a light-emitting diode member 102, a light guide plate 106, and a reflective sheet 108. The light emitting diode element 102 is disposed under the light guide plate 1〇6 and is adapted to provide a light. The photodiode element 102 may be a white light emitting diode element or a light emitting diode element of other color lights. . The light guide plate 106 has an upper surface I2963^, 0c/e '. The voxel: Γ 1() 4b ' has an intermediate portion 1G6a on the upper surface 104a, which is located in the true continuation of the light emitting diode, and a surrounding intermediate portion 106a.

The light guide plate 106 has a microstructure 11G and a plurality of second microstructures m, the first micro-junction is distributed in the intermediate region 1Q6a' and the second microstructure i2Q is distributed in the domain and the first micro-structure 11 (four) is reflected in the light. The microstructure 12 is capable of reflecting light. In other words, the first microstructures 110 are capable of totally reflecting most of the light, allowing only a small portion of the lines to pass through, while the second microstructures 12 are capable of making a smaller ratio than the first microstructures 11A. The light is totally reflected and allows a higher ratio of light to pass through. In addition, the reflective sheet 1〇8 is disposed below the light guide plate 106 to reflect light reflected from the bottom of the light panel 106 back into the light guide plate ι6.

When the microstructure is ι1〇', since the first microstructure 110 has a high reflective power for light, most of the light is totally reflected.
