[0044] The second embodiment - the manufacturing method of the light guide plate
[0045] Figure 2A to Figure 2C It is a flow chart of the manufacturing method of the light guide plate according to the second embodiment of the present invention. In this embodiment, the manufacturing method of the light guide plate is suitable for making Figure 1A The light guide plate 100. Please refer to Figure 2A , first provide a light-transmitting substrate 100'. The transparent substrate 100' has a direction D1 and a direction D2 perpendicular to each other. The transparent substrate 100' has at least a light incident surface S1 and a surface S2.
[0046] Next, please refer to Figure 2B , the optical microstructure 110 is formed on the entire surface S2 of the light-transmitting substrate 100' along the direction D1 starting from the light-incident surface S1. The optical microstructure 110 is, for example, a groove 112, wherein the shape of the groove 112 is selected from semic...

[0049] The third embodiment - light guide plate
[0050] image 3 It is a three-dimensional schematic diagram of a light guide plate according to a third embodiment of the present invention. The light guide plate 300 of this embodiment and Figure 1A The light guide plate 100 is similar to the light guide plate 100, but the main difference between the two is: the two sides of the light guide plate 300 are respectively provided with a transition area A2, and the two transition areas A2 are adjacent to the light incident surface S1 on both sides of the light guide plate 300, and the visible area A1 Located between the two transition areas A2. In other words, the light guide plate 300 of this embodiment is a double-sided light guide plate.
[0051] Likewise, there is a step difference H between the surface A1_S of the visible area A1 of the light guide plate 300 and the surface A2_S of the transition area A2 of the light guide plate 300 . In addition, the optical microstructur...

[0053] Fourth embodiment - light guide plate
[0054] Figure 4 It is a three-dimensional schematic diagram of a light guide plate according to a fourth embodiment of the present invention. The light guide plate 100A of this embodiment and Figure 1A The light guide plate 100 is similar to the light guide plate 100, but the main difference between the two is that the optical microstructure 120 is only disposed in a part of the transition area A2, and is adjacent to the position A2'_R of the visible area A1.
[0055] In addition, the method of manufacturing the light guide plate 100A is, for example: first, in the direction D1, from Figure 4 The optical microstructure 110 is formed from the right side to the left, but the optical microstructure 110 is only formed on a part of the light guide plate 100A (A1 and part A2'). Next, in the direction D2, remove the optical microstructure 110 formed in the partial area of A2' (the position A2'_R adjacent to the visible area A1), a...
