    Abstract: Phosphors or quantum dots cannot convert all the excitation lights, but the remaining excitation lights have to be absorbed with a color filter without passing through. A display device includes an array substrate having a color layer and an opposite substrate. The color layer includes a red fluorescence layer for converting blue light into red, a green fluorescence layer for converting blue light into green, and a blue fluorescence layer for compensating blue light. Both of the red fluorescence layer and the green fluorescence layer include the phosphors or quantum dots with two types of dominant wavelengths. The blue fluorescence layer includes the phosphors or quantum dots with one type of dominant wavelength.

    Abstract: According to an aspect, a detection device includes a plurality of light-receiving elements configured to receive light, and a light guide portion one surface of which faces the light-receiving elements. The light guide portion includes a plurality of light guide paths provided throughout from the one surface to the other surface of the light guide portion, and a light-absorbing portion having higher absorbance of the light than that of the light guide paths. When viewed from a direction in which the light-receiving elements and the light guide portion are stacked, more than one of the light guide paths overlap one of the light-receiving elements.
