The invention discloses a display panel and a manufacturing method therefor, and a display apparatus. The display panel comprises multiple light emitting
layers and filtering patterns corresponding to the light emitting
layers, wherein the filtering patterns are positioned above the corresponding light emitting
layers; the filtering patterns have special
transmittance spectra; and the filtering patterns are used for filtering light rays corresponding to spectra except the special
transmittance spectra, and transmitting the light rays corresponding to the special
transmittance spectra. According to the technical scheme of the display panel and the manufacturing method therefor, and the display apparatus, the filtering patterns are positioned in the light output direction of the corresponding light emitting layers; the filtering patterns have the special
transmittance spectra; and the filtering patterns are used for filtering the light rays corresponding to the spectra except the special
transmittance spectra, and transmitting the light rays corresponding to the special
transmittance spectra; partial light rays are filtered by the filtering patterns, so that the light rays transmitting the filtering patterns are reduced; and consequently, the
reflectivity of the ambient light irradiated to the display panel is lowered, so that the
contrast ratio of the display panel is further improved.
