Displaying base plate and fabricating method thereof, and display panel

A displaying base plate, wherein the displaying base plate comprises:

• a plurality of pixels that are arranged in an array, wherein each of the pixels comprises a first sub-pixel, a second sub-pixel and a third sub-pixel that have different luminous colors;
• the first sub-pixel comprises a first electrode, a first inorganic layer and a first quantum-dot layer that are sequentially stacked, wherein the first inorganic layer comprises a first inorganic material modified by a first radical group, and the first quantum-dot layer comprises a first quantum dot modified by a first ligand, wherein a wettability of the first radical group and a wettability of the first ligand are the same;
• the second sub-pixel comprises a second electrode, a second inorganic layer and a second quantum-dot layer that are sequentially stacked, wherein the second inorganic layer comprises a second inorganic material modified by a second radical group, and the second quantum-dot layer comprises a second quantum dot modified by a second ligand, wherein a wettability of the second radical group and a wettability of the second ligand are the same;
• and
• the third sub-pixel comprises a third electrode, a third inorganic layer and a third quantum-dot layer that are sequentially stacked, wherein the third inorganic layer comprises a third inorganic material modified by a third radical group, and the third quantum-dot layer comprises a third quantum dot modified by a third ligand, wherein a wettability of the third radical group and a wettability of the third ligand are the same;
• wherein each two of the wettability of the first radical group, the wettability of the second radical group and the wettability of the third radical group are different, and each two of the wettability of the first ligand, the wettability of the second ligand and the wettability of the third ligand are different.
