Abstract:
A novel display panel that is highly convenient or reliable is provided. The display panel includes a first pixel; the first pixel includes a first display element, a first color conversion layer, and a first absorption layer; the first display element emits first light; the first absorption layer overlaps with the first display element; and the first absorption layer absorbs the first light. Furthermore, the first color conversion layer is sandwiched between the first display element and the first absorption layer; the first color conversion layer converts the first light into second light; and the second light has a spectrum including a high proportion of light with a long wavelength compared with the first light.
