Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a near-infrared cut filter. More specifically, it is a near-infrared cut filter having a sufficient viewing angle, in particular, a viscous correction filter for a solid-state imaging device such as a CCD 'CMOS. [Prior Art] In recent years, televisions equipped with plasma display panels (PDPs) have been commercialized and widely used in general households. The PDP is a display that is operated by plasma discharge, but it is known that near-infrared rays (wavelength: 800 to 100 nm) occur when the plasma is discharged. On the other hand, in the home, the remote control of home appliances such as televisions, radios, or air conditioners, and the exchange of data on personal computers, have increased the number of near-infrared rays. It is often pointed out that the near-infrared rays emitted by PDPs are the cause of malfunction of such machines. The possibility is high. Therefore, most of the commercially available PDPs have a filter function for the near-infrared rays emitted from the front panel. Further, a camera, a digital camera, a mobile phone with a camera function, and the like use a CCD or a CMOS image sensor of a solid-state imaging device of a camera pixel, but these solid-state imaging elements have sensitivity to near-infrared rays in their light-receiving portions. For the dimming diode, it is necessary to perform the visual sensitivity correction and most of them use a near-infrared cut filter. As for the near-infrared cut-off filters', various methods have been used since the past. Practically, for example, a metal such as silver is vapor-deposited on the surface of 201211125 of a transparent substrate such as glass, and a near-infrared absorbing pigment is added to a transparent resin such as an acrylic resin or a polycarbonate resin. However, the near-infrared cut-off filter for vapor-depositing a metal on a glass substrate not only increases the manufacturing cost, but also has a problem that the glass piece of the substrate is mixed as a foreign matter at the time of cutting off. In addition, when an inorganic material is used as the substrate, there is a limit in terms of thinning and miniaturization of the solid-state imaging device in recent years. Japanese Patent Publication No. Hei 6-200 1 1 3 (Patent Document 1) discloses a near-infrared cut filter that uses a transparent resin as a substrate and a near-infrared absorbing dye in a transparent resin. However, the near-infrared cut filter described in Patent Document 1 may not necessarily have sufficient near-infrared absorption energy. In addition, the present applicant proposes a near-infrared cut filter having a base plate made of a base borneol resin and a near-infrared reflecting film, in JP-A-200-323883 (Patent Document 2). [PRIOR ART DOCUMENT] [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. 2005-3 3 8395. The near-infrared cut-off filter described in Document 2 is excellent in the cut-off resistance, moisture absorption resistance, and impact resistance of near-infrared -6 - 201211125, but may not be sufficient. SUMMARY OF THE INVENTION The object of the present invention is to obtain a wide viewing angle, excellent near-infrared cutoff performance, low hygroscopicity, and no foreign matter or warpage, and is particularly applicable to a near-infrared cut filter for solid-state imaging devices such as CCD and CMOS. Further, the object of the present invention is to provide a solid-state imaging device which is thin and excellent in impact resistance.

Further, in the conventional near-infrared cut-off filter, the compound (I) is based on its transmittance. The curve has a steep slope, and the absorption region in the near-infrared region is narrow, and when the near-infrared cut filter is mixed in a substrate such as glass, the compound (I) cannot withstand the forming temperature of the glass. It cannot be used. Therefore, it is impossible to obtain a near-infrared cut filter which is particularly small in incident angle dependence of the present invention. Since the resin substrate (I) containing the compound (I) has the characteristics (E) and (F) described above, the near-infrared cut filter of the present invention particularly has the following (A), (C), and (Features of D).

Poly(aryl ether oxide) phosphine resin (PEP0), polyimide resin (PPI), polyamidimide resin (PAI), (modified) acrylic resin, polycarbonate resin (PC), polynaphthalene Ethylene dicarboxylate (PEN) and organic-inorganic nanocomposite. In the above-mentioned resin, when a cyclic olefin resin or an aromatic polyether resin having high transparency is used, the transmittance in the visible light region is particularly high, and it is preferable that -26-201211125 has a low hygroscopicity of the resins. It is not easy to produce warpage, so it is preferable. In particular, when the original borneol-based resin or the aromatic polyether-based resin is used as the resin, the compound (I) has good dispersibility to the original borneol-based resin. Therefore, a substrate having excellent optical characteristics and excellent moldability can be obtained. <Cyclic olefin resin> The transparent resin used in the present invention is exemplified by a cyclic olefin resin.

(Α) In the range of wavelength 430 to 580 nm, the transmittance at the time of measurement from the vertical direction of the near-infrared cut filter is preferably at least 75% or more, preferably 78% or more, more preferably 80% or more. . In the present invention, by using -63-201211125 for thickness 0. A resin having a high total light transmittance of 1 mm and having no absorption compound (I) or the like in the wavelength region can be obtained as a near-infrared cut filter having a high transmittance at a wavelength of 430 to 580 nm. When the near-infrared cut-off filter is used for a luminosity correction filter or the like in a lens unit such as a solid-state imaging device or a camera module, it is preferable that the average transmittance of the transmittance at a wavelength of 430 to 580 nm is within the aforementioned range, and at the wavelength The transmittance in the range is fixed. The average 値 of the transmittance in the wavelength range of 43 0 to 5 80 nm is preferably higher. If the average value of the transmittance is high, the intensity of light passing through the filter can be sufficiently ensured, and it can be preferably used for the above-mentioned use. On the other hand, if the average transmittance of the light in the range of the wavelength of 43 0 to 500 nm is low, the intensity of the light passing through the filter cannot be sufficiently ensured, and therefore it is not suitable for the above-mentioned use. (B) In the range of wavelengths of 00 to 100 nm, the transmittance at the time of measurement from the vertical direction of the near-infrared cut filter is preferably 20% or less, preferably 15% or less, more preferably 10% or less. value. In the present invention, by providing a specific near-infrared reflecting film having high near-infrared reflection energy on the resin substrate (I), it is possible to obtain a near-infrared cut filter having a sufficiently low transmittance at a wavelength of 800 to 1 000 nm. In the near-infrared cut filter of the present invention, in order to selectively reduce the wavelength of near-infrared rays (800 nm or more), the average transmittance of light in the range of 800 to 1 OOO nm is preferably lower. When the average transmittance is low, the near-infrared cut-off filter can sufficiently cut off near-infrared rays. On the other hand, if the transmittance of the wavelength in the range of 800 to 1 000 nm is 値-64-201211125, if the filter is high, the filter cannot sufficiently cut off the near-infrared rays. When the filter is used for a PDP or the like, it may not be prevented in the home. The electronic equipment around the PDP is mistaken. (C) In the wavelength region of 800 nm or less, the transmittance at the time of measurement from the vertical direction of the near-infrared cut filter becomes the longest wavelength (Xa) of 70%, and in the wavelength region of the wavelength of 580 nm or more, the near-infrared ray is cut off. The absolute 値(|Xa_Xb|) of the difference between the shortest wavelength (Xb) at which the transmittance is 30% in the vertical direction of the filter is preferably less than 75 nm, preferably less than 72 nm, more preferably less than 70 nm. In the present invention, by using the above compound (I), a near-infrared cut filter having an absolute 差 which is a difference in wavelength of a specific transmittance in the above specific range can be obtained. If the absolute value of the difference between (Xa) and (Xb) of the near-infrared cut filter is within the above range, the transmittance between the wavelengths (Xa) and (Xb) near the wavelength region of the near-infrared rays changes rapidly, so The near-infrared rays are effectively cut off, and a near-infrared cut filter having a small absolute difference between (Ya) and (Yb), a small dependence of an incident angle of an absorption wavelength, and a wide viewing angle can be obtained. (D) In the range of wavelength 560 to 800 nm, preferably in the range of 580 to 800 nm, the transmittance at the time of measurement from the vertical direction of the near-infrared cut filter becomes 50% (Ya), and The vertical direction with respect to the near-infrared cut filter is 30. The absolute 値(|Ya-Yb|) of the difference between the wavelengths (Yb) at which the transmittance is 50% is preferably less than 15 nm', preferably less than 13 nm, more preferably less than 10 nm. In the present invention, by using the above-mentioned compound (I), a near-infrared-line cut filter which is an absolute enthalpy of the difference in wavelength between the wavelengths of the specific wavelength of -65 - 201211125 can be obtained within the above specific range. When the absolute value of the difference between (Ya) and (γ) is within the above range in the range of 560 to 800 nm, when the filter is used for a PDP or the like, when viewing the display from an oblique direction, it is also displayed and viewed from the vertical direction. In the case of the same brightness and color tone, a near-infrared cut filter having a small incident angle dependence of the absorption wavelength and a wide viewing angle can be obtained. On the other hand, the absolute value of the difference between (Ya) and (Yb) is i5 nm or more. When the near-infrared cut-off filter is used for a PDP or the like, there is a case where the brightness is remarkably reduced as the angle of the display is viewed, the color tone is reversed, and the specific color is not easily seen, so that it is not suitable for the above-mentioned use. When the "viewing angle" is viewed from the top, bottom, left, and right, the display shows an angle at which a certain position of the screen can be normally seen. In the present invention, when the near-infrared cut filter is viewed from the top, bottom, left, and right, the position angle of the normal viewing screen is displayed. The judgment of whether or not the normal viewing is possible in the present invention is the transmission in the vertical direction of the filter in the range of the wavelength of 560 to 800 nm.値 (Ya) which is 50% of the wavelength, and the absolute 値 of the difference (Yb) between the wavelengths at which the transmittance becomes 50% from the direction perpendicular to the vertical direction of the filter becomes less than 15 nm as a reference. The thickness of the near-infrared cut filter is preferably adjusted so that the transmittance of the filter satisfies the above (A) to (D), and is not particularly limited, but is preferably 50 to 250 nm, more preferably 50 to 200 nm. Further, it is preferably 80 to 150 nm. When the thickness of the near-infrared cut filter is within the above range, the filter can be reduced in size and weight, and can be preferably used in various applications such as a solid-state imaging device. In particular, when a lens unit such as a camera module is used, it is preferable to reduce the thickness of the lens unit. <Application of Near Infrared Cut Filter> The near-infrared cut filter obtained in the present invention has a wide viewing angle and excellent near infrared rays. It can be used for the visual sensitivity compensation of a solid-state imaging device such as a CCD or a CMOS of a camera module. In particular, it can be used for a digital camera, a camera for a mobile phone, and a digital video recorder. , PC cameras, surveillance cameras, automotive cameras, televisions, car navigation, mobile data terminals, personal computers, video game consoles, medical devices, USB devices, portable game consoles, fingerprint recognition systems, digital music players, It is also useful as a hot wire cut-off filter or the like for mounting on a glass such as a car or a building, etc. Here, the near-infrared cut filter obtained by the present invention is used for a camera module. Fig. 1 shows a schematic cross-sectional view of a camera module. Fig. 1 (a) is a schematic cross-sectional view showing the structure of a conventional camera module, and Fig. 1 (b) is a view showing the use of the present invention. In the case of the infrared cut filter 6', a schematic cross-sectional view of one of the configurations of the camera module can be obtained. In Fig. 1(b), the near-infrared cut filter 6' obtained by the present invention is used in the upper portion of the lens 5, but the near-infrared cut filter 6' obtained in the present invention can also be used in Fig. 1(a). The lens 5 shown is between -67 and 201211125 of the sensor 7. In the past, the camera module light had to be incident almost perpendicularly to the near-infrared cut filter 6. Therefore, the filter 6 must be disposed between the lens 5 and the sensor 7. Here, since the sensor 7 is highly sensitive and has no contact with dust or dust of about 5 μ, the filter 6 used in the upper portion of the sensor 7 is dust-free or dust-free. It is necessary to be free of foreign objects. Further, due to the characteristics of the above-described sensor 7, it is necessary to provide a specific interval between the filter 6 and the sensor 7, so as to hinder the thinning of the camera module. On the other hand, the absolute 差 of the difference between (Ya) and (Yb) of the near-infrared cut filter 6' obtained by the present invention is 15 nm or less. That is, the light incident from the vertical direction of the filter 6' is not much different from the transmission wavelength of light incident at 30° from the vertical direction of the filter 6' (incidence angle of absorption (transmission) wavelength) Since the dependency is small, the filter 6' does not need to be disposed between the lens 5 and the sensor 7, and may be disposed on the upper portion of the lens. Therefore, when the near-infrared cut filter 6' obtained by the present invention is used for a camera module, the operability of the camera module becomes easy, and a specific interval is not required between the filter 6' and the sensor 7. Therefore, the thinning of the camera module is made possible.
