Title:
近赤外線カットフィルタ、固体撮像素子、カメラモジュールおよび画像表示装置
Document Type and Number:
Japanese Patent JP6650040
Kind Code:
B2
Abstract:
Provided are a near-IR-cut filter which is excellent in visible transparency and IR shielding property and, when incorporated in a solid state imaging device, makes it possible to obtain an image in which purple fringes are suppressed; a solid state imaging device; a camera module; and an image display device. The near-IR-cut filter includes a copper complex and has the transmittance T450 of 85% or more, the ratio T350/T450, which is the ratio of the transmittance T350 and the transmittance T450, of 0-0.3, and the ratio T700/T550, which is the ratio of the transmittance T700 and the transmittance T550, of 0-0.2. The average value of the reflectance of the near-IR-cut filter is 80% or less in the range of 800-1000 nm.
