1. A display panel comprising:
a display region,
wherein the display region comprises a first pixel, a second pixel, a third pixel and a filter,
wherein the first pixel is configured to emit light with a spectrum including a local maximum at a first wavelength,
wherein the second pixel is configured to emit light with a spectrum including a local maximum at a second wavelength,
wherein the third pixel is configured to emit light with a spectrum including a local maximum at a third wavelength,
wherein the filter comprises a first region, a second region and a third region,
wherein the first region and the first pixel overlap each other,
wherein the second region and the second pixel overlap each other,
wherein the third region and the third pixel overlap each other,
wherein the first region, the second region and the third region have the same transmittance spectrum,
wherein the transmittance spectrum has local minimums at a fourth wavelength and a fifth wavelength,
wherein the second wavelength is longer than the first wavelength,
wherein the third wavelength is longer than the second wavelength,
wherein the fourth wavelength is between the first wavelength and the second wavelength, and
wherein the fifth wavelength is between the second wavelength and the third wavelength.
