Abstract

A method of reducing color breakup of reflection of ambient light in a display panel having a color breakup-prevention structure is provided. The color breakup-prevention structure includes a high refractive index lens layer on a side of a plurality of light emitting elements away from a base substrate; a low refractive index modulation layer on a side of the high refractive index lens layer away from the base substrate; a first color filter layer in a plurality of subpixel regions, and spaced apart from the high refractive index lens layer by the low refractive index modulation layer; and a first black matrix layer in an inter-subpixel region, and spaced apart from the high refractive index lens layer by the low refractive index modulation layer. The high refractive index lens layer includes a plurality of lens portions spaced apart from each other and respectively in the plurality of subpixels.
