An organic light emitting diode display panel according to an embodiment of the present invention comprises: an organic light emitting diode layer; a color filter layer; and a color change reduction layer which is positioned between the organic light emitting diode layer and the color filter layer, wherein the organic light emitting diode layer includes a first light emitting unit including a first light emitting layer generating first light and a second light emitting unit including a second light emitting layer generating second light, third light made by synthesizing the first light with the second light is output from the organic light emitting diode layer and is input to the color change reduction layer, light output from the color change reduction layer is the fourth light, and the difference between an intensity decrease width of a peak in the blue wavelength band and an intensity decrease width of a peak in the yellow-green wavelength band according to an increase in a viewing angle in the EL spectrum of the fourth light may be smaller than the difference between the intensity decrease width of a peak in the blue wavelength band and an intensity decrease width of a peak in the yellow-green wavelength band according to an increase in the viewing angle in the EL spectrum of the third light. |
