Abstract: A display panel includes a first display portion and at least one second display portion. The first display portion includes first sub-pixels and has at least one arc-shaped border. The second display portion is connected to an arc-shaped border and includes first sub-portions and one or more second sub-portions. The first sub-portion includes second sub-pixels, the first sub-portions are sequentially arranged along the arc-shaped border, and in a case where the first display portion and the second display portion are laid on a reference plane, any two adjacent first sub-portions have a gap therebetween. The second sub-portion includes third sub-pixels; at least one second sub-portion is located in a gap between two adjacent first sub-portions and is connected to at least one of the two adjacent first sub-portions. A Young's modulus of the first sub-portion is greater than a Young's modulus of the second sub-portion.
