Claim:
1. A display panel, comprising a color filter layer, wherein a reflective filter is provided below the color filter layer; and the reflective filter is configured to reflect light with wavelength smaller than a predetermined value and configured to transmit light with wavelength greater than or equal to the predetermined value, and the reflective filter and a liquid crystal layer of the display panel are provided on a same side of the color filter layer, wherein a main film system of the reflective filter is represented as follows: ((H/2) L (H/2)) M ; where H stands for a first film layer; H/2 stands for a second film layer having a same refraction index as the first film layer, a thickness of the second film layer is half of a thickness of the first film layer; L stands for a third film layer; and M stands for a mount of period, wherein a formula of calculating the mount of period M is as follows: TR=(16n o n g )/(n H /n L ) 2M {(n o +n g ) 2 +(((n o n g )/n H )−n H ) 2 }); where T R stands for transmittance of the reflective filter at a central wavelength of a stop band, n o stands for a refraction index of an upper base of the reflective filter, n g stands for a refraction index of a lower base of the reflective filter, n H stands for a refraction index of the first film layer, and n L stands for a refraction index of the third film layer.
