Embodiment 1

[0116] (1-1. Fabrication of Optical Body)

[0117] Figure 7 It shows the structure of the optical body 1-1 which concerns on Example 1. In Example 1, the optical body 1-1 was produced through the following process. First, as a substrate 10-1, a polymethyl methacrylate film (manufactured by Sumika Acrylic Sales Co., Ltd., Technolloy) having a thickness of 150 μm was prepared. Next, use Image 6 The transfer apparatus 300 shown in 10 forms the second fine concave-convex structure 12 on one surface (here, the second surface 10B) of the substrate 10-1. Here, as the photocurable resin composition, an ultraviolet curable acrylic resin composition (SK1120 manufactured by Dexerials Corporation) was used. In addition, in order to improve the adhesiveness of the substrate 10-1 and the cured layer of the uncured resin layer, the second surface 10B of the substrate 10-1 is subjected to primer treatment in advance. By the primer treatment, a primer layer having a thickness of approxi...

Embodiment 2

[0136] (2-1. Fabrication of Optical Body)

[0137] Figure 8The structure of the optical body 1-2 concerning Example 2 is shown. In Example 2, the optical body 1-2 was produced by using the optical body 1-1 as a transfer mold. Specifically, first, the substrate 10-1 used in Example 1 was prepared. Next, primer treatment is performed on both surfaces of the base material 10-1 in order to improve the adhesiveness between the base material 10-1 and each cured layer described later. The details of the primer treatment were the same as in Example 1. A primer layer having a thickness of approximately 3 μm was formed on both surfaces of the substrate 10-1 by the primer treatment. Next, an uncured resin layer of the photocurable resin composition is formed on one surface (here, the second surface 10B) of the base material 10-1. Next, the shape of the second surface 10B of the optical body 1 - 1 , that is, the second fine uneven structure 12 and the coarse uneven structure 13 is t...

Embodiment 3

[0142] (3-1. Fabrication of Optical Body)

[0143] Figure 9 It shows the structure of the optical body 1-3 which concerns on Example 3. Optical body 1-2 was used as a transfer mold in Example 3 to produce optical body 1-3. Specifically, first, the substrate 10-1 used in Example 1 was prepared. Next, primer treatment is performed on both surfaces of the base material 10-1 in order to improve the adhesiveness between the base material 10-1 and each cured layer described later. The details of the primer treatment were the same as in Example 1. A primer layer having a thickness of approximately 3 μm was formed on both surfaces of the substrate 10-1 by the primer treatment.

Abstract

The present invention provides a light emitting device that can be used as a light guide plate and has an excellent anti-reflection function for external light. In order to solve the above-mentioned problems, according to a certain viewpoint of the present invention, an optical body is provided, which includes: a base material; The inner propagating light to the inside of the substrate is emitted from the other surface of the substrate; and a fine concave-convex structure which is periodically formed following both surfaces of the substrate and a surface of a coarse concave-convex structure, the average period of the concave-convex is below the wavelength of visible light The surface of the coarse concave-convex structure has an inclined surface inclined at an angle of not less than 30° and less than 90° with respect to one surface, and the arrangement of the fine concave-convex structure is arranged in a staggered manner with respect to the traveling direction of internal propagating light.

Description

technical field [0001] The invention relates to an optical body and a light emitting device. Background technique [0002] As one type of optical body, an optical body is known in which a waveguide phenomenon of light and a macro concave-convex structure (macro concave-convex structure) are combined. Such an optical body is also called a light guide. A coarse concavo-convex structure is formed on one surface of the light guide plate. In addition, light enters the inside of the light guide plate from the light source provided on the side surface of the light guide plate. The light incident on the inside of the light guide plate, that is, the internal propagating light propagates inside the light guide plate while being reflected on the surface of the light guide plate (ie, the interface between the inside and outside of the light guide plate). After that, the internal propagating light is reflected at the surface of the rough concave-convex structure, and is emitted from t...
