Title:
SOLID-STATE IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/088645
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a solid-state imaging device that minimizes production costs and that has high detection accuracy. A solid-state imaging device is provided with: a first optical layer that transmits visible light and at least a part of near-infrared light; a second optical layer that absorbs at least a part of near-infrared light; and a pixel array comprising a first light-receiving element that detects the visible light transmitted by the first and second optical layers and a second light-receiving element that detects the near-infrared light transmitted by the first optical layer. The second optical layer comprises an opening in a part thereof corresponding to the second light-receiving element. The first optical layer contains a compound (A) having at least one absorbance maximum at a wavelength of 750-900 nm. The second optical layer contains a compound (B) having at least one absorbance maximum at a wavelength of 755-1050 nm. The absorbance maximum wavelength on the longest wavelength side of the compound (B) is larger than the absorbance maximum wavelength on the longest wavelength side of the compound (A), and the difference therebetween is 5-150 nm.
