  • Solid-state imaging device, infrared-absorbing composition, and flattened-film-forming curable composition
    Patent number: 10854661
    Abstract: Provided is a solid-state imaging device that includes: a first pixel provided with a color filter layer having a transmission band in a visible light wavelength region on a light-receiving surface of a first light-receiving element; a second pixel provided with an infrared pass filter layer having a transmission band in an infrared wavelength region on a light-receiving surface of a second light-receiving element; an infrared cut filter layer that is provided on a position overlapping with the color filter layer and transmits light in the visible light wavelength region by blocking light in the infrared wavelength region; and a cured film provided in contact with the infrared cut filter layer.
    Type: Grant

  • SOLID-STATE IMAGING DEVICE AND INFRARED-ABSORBING COMPOSITION
    Publication number: 20170317131
    Abstract: Provided is a solid-state imaging device that includes: first pixels provided with a color filter layer having a transmission band in a visible light wavelength region on a light-receiving surface of a first light-receiving element; second pixels provided with an infrared pass filter layer having a transmission band in an infrared wavelength region on a light-receiving surface of a second light-receiving element; and an infrared cut filter layer that is provided on a lower surface side of the color filter layer and transmits light in the visible light wavelength region by blocking light in the infrared wavelength region; wherein the infrared cut filter layer is formed with an infrared-absorbing composition containing a compound having a maximum absorption wavelength in an wavelength range of from 600 to 2000 nm, and at least one kind selected from a binder resin and a polymerizable compound.
