Array substrate and fabricating method thereof, and display device

A fabricating method of an array substrate, comprising:

• providing a back plate comprising a planar portion and a curved portion;
• forming a light emitting layer and a pixel defining layer on the back plate, the pixel defining layer dividing the light emitting layer into at least a first light emitting unit and a second light emitting unit, wherein a wavelength of a light emitted by the first light emitting unit is greater than a wavelength of a light emitted by the second light emitting unit, and the pixel defining layer comprises a first pixel defining region on the curved portion, and adjacent to the first light emitting unit and close to the planar portion;
• and
• forming a correction layer at a side of the first pixel defining region away from the back plate.

A display device comprising:

• an array substrate, comprising:
• a back plate comprising a planar portion and a curved portion;
• a light emitting layer at a first surface of the back plate, the light emitting layer comprising first light emitting units and second light emitting units that are spaced apart from each other, and a wavelength of a light emitted by the first light emitting unit being greater than a wavelength of a light emitted by the second light emitting unit;
• a pixel defining layer at a first side of the back plate and between the first light emitting unit and the second light emitting unit, the pixel defining layer comprising a first pixel defining region on the curved portion, and adjacent to the first light emitting unit and close to the planar portion;
• and
• a correction layer at a side of the first pixel defining region away from the back plate for absorbing and reflecting the light emitted by the first light emitting unit.
