Definitions
- a linear Fresnel lens sheet 4 is bonded to the surface of the first light diffusion layer 1 on the side opposite to the second light diffusion layer 2 (light source side).
- a linear Fresnel lens sheet 4 may be bonded to the surface of the second light diffusion layer 2 on the side opposite to the first light diffusion layer 1, and in this case, the second light diffusion layer 2 side is the light source side, It is preferable to dispose the transmissive screen so that the first light diffusion layer 1 side is the observation side.
- the light-transmitting plastic layer 12 is made of a light-transmitting plastic base material 12 A and does not contain a light diffusing material, and has a thickness T 12 of about 500 to 100 ⁇ m. is there.
- the light diffusing layer 13 has a refractive index difference of 0.05 or more from the transparent resin (translucent resin) 13 A constituting the light diffusing layer 13 and a volume average particle diameter of 1 to 8 m.
- the light diffusion material 13B has a strength of 10 to 60 g / m 2 .
- the bonding between the polarizing film layer 15 and the light diffusing layer 13 and the translucent plastic layer 16 must be performed beforehand on both sides of the polarizing film 15 or on one side of the light diffusing layer 13 and the colorless transparent or colored transparent plastic sheet 16. This can be done with a transparent adhesive formed on the substrate.
- the type of adhesive material is not particularly limited as long as it has adhesiveness to both sheets and is colorless or colored and transparent, and the pressure-sensitive adhesive can be selected from commonly used materials such as IJ, water-based adhesives, and UV-type adhesives. It is possible to select and use as appropriate.
- the refractive index of the adhesive is the refraction at the interface In order to suppress the reflected light due to the difference in the refractive index, it is desirable that the refractive index be as close as possible to the refractive index of the plastic sheet used.
- a light absorbing agent such as a pigment or a dye such as carbon black or a neodymium compound is appropriately selected in the translucent resin together with the spherical coated particles 26. (For example, about 50 to 200 ppm).
- the light absorption characteristics of the light absorber used are not particularly limited, but may have selective absorption by wavelength according to the purpose.
- Polarizing film 9 manufactured by Volatechno ⁇ — 1 825 T D (Single transmittance
- a transmission screen was obtained in the same manner as in Example 7, except for using 44%: 95% of the degree of polarization.
- the integrated sheet is laminated via an adhesive layer with a sheet in which the above-mentioned translucent plastic sheet and the light-diffusing sheet are integrated, and a transmissive sheet having the structure shown in FIG. Got the screen.
- a transmissive sheet having the structure shown in FIG. Got the screen.
