no. 1 Embodiment approach ＞
[0039] figure 1 It is a perspective view which shows the optical element (sunglasses) provided with the optical sheet (1st Embodiment) of this invention. figure 2 It is a perspective view which shows the optical element (sun visor) provided with the optical sheet (1st embodiment) of this invention. image 3 yes figure 1 An enlarged cross-sectional view of an optical sheet included in the shown lens with an optical sheet.
[0040] In addition, in figure 1 , figure 2 Among them, when the sunglasses are worn on the user's head, the surface of the lens on the user's eye side is also referred to as the back surface, and the surface on the opposite side is also referred to as the front surface. That is, in image 3 (about Figure 4 , Figure 5 In the same way), the left side is the "front side", and the right side is the "back side". and, in image 3 (about Figure 4 , Figure 5 In the same way), the thickness direction of the optical sheet is shown exaggeratedly, but i...
no. 2 Embodiment approach ＞
[0117] Figure 4 It is an enlarged cross-sectional view of the optical sheet (second embodiment) of the present invention.
[0118] Hereinafter, the second embodiment of the optical sheet of the present invention will be described with reference to this figure, but the differences from the above-mentioned embodiment will be mainly described, and the description of the same matters will be omitted.
[0119] This embodiment is the same as the first embodiment except that it has a polarizing layer.
[0120] Such as Figure 4 As shown, in this embodiment, the optical sheet 10 further includes the polarizing layer 5 and the adhesive layer 6 . In the optical sheet 10 of this embodiment, from the lens 7 side, the second base material 2, the adhesive layer 6, the polarizing layer 5, the adhesive layer 4, the half mirror layer 3, and the first base material 1 Sequential cascading.
[0121] (Polarizing layer)
[0122] The polarizing layer 5 is provided between the second base mater...
no. 3 Embodiment approach ＞
[0134] Figure 5 It is an enlarged cross-sectional view of the optical sheet (third embodiment) of the present invention.
[0135] Hereinafter, the third embodiment of the optical sheet of the present invention will be described with reference to this figure, but the description will focus on the points different from the above-mentioned embodiment, and the description of the same matters will be omitted.
[0136] This embodiment is the same as the first embodiment except that the adhesive layer contains a coloring material.
[0137] Such as Figure 5 As shown, in the optical sheet 10 of this embodiment, the second base material 2 , the half mirror layer 3 , the adhesive layer 4 , and the first base material 1 are laminated in this order from the lens 7 side. Furthermore, in this embodiment, the adhesive layer 4 contains a coloring material. The coloring material is preferably one of quinoline dyes, anthraquinone dyes, perylene dyes, polymethine dyes, porphyrin complex dyes...
