Abstract
A structure has a color filter having two or more different types of pixels and an absorption layer including at least one selected from a yellow colorant or a colorant having a maximum absorption wavelength in a wavelength range of 400 to 500 nm, in which the structure has the absorption layer on an optical path of at least one pixel of the pixels of the color filter and on the side through which light is incident on the pixel.
Claims25
A structure comprising:
- a color filter having two or more different types of pixels;
- and
- an absorption layer including at least one colorant Y selected from a yellow colorant or a colorant having a maximum absorption wavelength in a wavelength range of 400 to 500 nm,
- wherein the colorant Y includes C. I. Pigment Yellow 150, and
- 50% by mass or more of the colorant Y is at least one selected from C. I. Pigment Yellow 150, C. I. Pigment Yellow 139, or C. I. Pigment Yellow 185, and
- the structure has the absorption layer on an optical path of at least one pixel of the pixels of the color filter and on the side through which light is incident on the pixel.
A method for producing a structure, the method comprising:
- forming a color filter;
- and
- forming an absorption layer,
- wherein the color filter has two or more different types of pixels,
- the absorption layer includes at least one colorant Y selected from a yellow colorant or a colorant having a maximum absorption wavelength in a wavelength range of 400 to 500 nm,
- the structure has the absorption layer on an optical path of at least one pixel of the pixels of the color filter and on the side through which light is incident on the pixel,
- forming an absorption layer includes applying a composition for forming an absorption layer, the composition including at least one colorant Y selected from a yellow colorant or a colorant having a maximum absorption wavelength in a wavelength range of 400 to 500 nm,
- the colorant Y includes C. I. Pigment Yellow 150, and
- 50% by mass or more of the colorant Y is at least one selected from C. I. Pigment Yellow 150, C. I. Pigment Yellow 139, or C. I. Pigment Yellow 185.
