Claim 17:
18. A method of fabricating a display panel, comprising:
forming a plurality of light emitting elements on a base substrate and respectively in a plurality of subpixels; and
forming a color breakup-prevention structure configured to reduce color breakup of reflection of ambient light in the plurality of subpixels;
wherein forming the color breakup-prevention structure comprises:
forming a high refractive index lens layer on a side of the plurality of light emitting elements away from the base substrate;
forming a low refractive index modulation layer on a side of the high refractive index lens layer away from the base substrate;
forming a first color filter layer in a subpixel region, and spaced apart from the high refractive index lens layer by the low refractive index modulation layer; and
forming 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;
wherein the high refractive index lens layer has a first refractive index;
the low refractive index modulation layer has a second refractive index smaller than the first refractive index;
the low refractive index modulation layer is substantially transparent and substantially free of a chromogenic material; and
forming the high refractive index lens layer comprises forming a plurality of lens portions spaced apart from each other and respectively in the plurality of subpixels;
wherein forming the color breakup-prevention structure further comprises:
forming a second color filter layer in the subpixel region, and spaced apart from the low refractive index modulation layer by the high refractive index lens layer; and
forming a second black matrix layer in the inter-subpixel region, and spaced apart from the low refractive index modulation layer by the high refractive index lens layer.
