Problems solved by technology

The disadvantage of this method is that the mask needs to be replaced periodically according to the life of the mask, which increases the manufacturing cost, and because the panel and the ink on which the pattern is formed are made of different materials, there is a difference in the refractive index of light. , so it is not easy to control the light, and the adhesive force between the panel and the ink material will also cause problems

[0064] First, if image 3 As shown in a, a mold 300 with a predetermined pattern is prepared, and a mixture 200 a of methyl methacrylate (Methyl Methacrylate: MMA) 220 and a light diffusing agent 210 is coated on the mold 300 . Accordingly, the mixture 200 a of the light diffusing agent 210 and methyl methacrylate (MMA) 220 is patterned corresponding to the pattern of the mold 300 .

[0065] Next, if image 3 As shown in b, a substrate 100 made of polymethyl methacrylate (PMMA) is laminated on the mixture 200 a coated on the mold 300 .

[0066] Next, if image 3 As shown in c, make the mixture formed into the predetermined pattern (refer to image 3 200a) of b is cured.

[0067] The curing step includes a step of polymerizing the methyl methacrylate (MMA) into polymethyl methacry...

[0071] Figure 4 a to Figure 4 f is a cross-sectional view schematically showing the manufacturing process of the optical component according to the third embodiment of the present invention.

[0072] First, if Figure 4 As shown in a, a sealing member 450 is formed on the edge of the lower mold 410 .

[0073] The lower mold 410 is composed of a flat panel, and the sealing member 450 can be fixed on the edge of the lower mold 410 by a predetermined adhesive.

[0074] Next, if Figure 4 As shown in b, the substrate 100 made of polymethyl methacrylate (PMMA) is mounted on the lower mold 410 inside the sealing member 450 .

[0075] Next, if Figure 4 As shown in c, an upper mold 430 having a predetermined pattern is prepared, and the upper mold 430 is fixed to the sealing member 450 with the predetermined pattern facing the lower mold 410 .

[0076] The pattern of the upper mold 430 is formed in consideration of the pattern of the optical component to be finally obtained. ...
