1. A display panel, comprising:
an array substrate;
a plurality of pixel units disposed on the array substrate, the pixel units respectively comprising a plurality of anodes composed of an opaque material, a plurality of light-emitting portions and a plurality of cathodes that are sequentially stacked;
an encapsulation layer disposed on the pixel units; and
a touch layer disposed on the encapsulation layer,
wherein the display panel comprises a first display area and a second display area disposed adjacent to the first display area, and a light transmittance of the touch layer in the first display area is less than a light transmittance of the touch layer in the second display area;
in the first display area, the pixel units comprise first pixel units and second pixel units, and a minimum distance between an edge of one of the anodes of at least one of the second pixel units and an edge of one of the light-emitting portions of the at least one of the second pixel units is greater than a minimum distance between an edge of one of the anodes of each of the first pixel units and an edge of one of the light-emitting portions of the each of the first pixel units;
the anodes respectively comprise a plurality of first portions respectively overlapping the plurality of light-emitting portions and a plurality of second portions respectively disposed around the first portions, ones of the second portions of the first pixel units respectively have minimum widths as first widths, ones of the second portions of the second pixel units respectively have minimum widths as second widths, and at least one of the second widths is greater than each of the first widths; and
each of the ones of the second portions of the first pixel units forms a first annular portion, and a difference between a maximum width and a minimum width of the first annular portion is defined as a; each of the ones of the second portions of the second pixels forms a second annular portion, and a difference between a maximum width and a minimum width of the second annular portion is defined as b; and 0 μm≤a≤0.1 μm, and b≥0 μm.
