Abstract
A novel display panel that is highly convenient, useful, or reliable is provided. The display panel includes a display region and includes a first pixel, a second pixel, a third pixel, and a filter. The first pixel emits light with a spectrum having a local maximum at a first wavelength, the second pixel emits light with a spectrum having a local maximum at a second wavelength, and the third pixel emits light with a spectrum having a local maximum at a third wavelength. The filter includes a region overlapping with the first pixel, a region overlapping with the second pixel, and a region overlapping with the third pixel, and the filter has a transmittance spectrum having local minimums at a fourth wavelength and a fifth wavelength. The second wavelength is longer than the first wavelength. The third wavelength is longer than the second wavelength. The fourth wavelength is between the first wavelength and the second wavelength. The fifth wavelength is between the second wavelength and the third wavelength.
