1. A display panel comprising:
an array substrate comprising:
a substrate; and
a display region comprising:
a color filter;
a pixel electrode; and
a first transistor,
wherein the color filter, the pixel electrode, and the first transistor are located on a same side of the substrate;
wherein the first transistor comprises a first semiconductor layer;
wherein, along a direction perpendicular to a plane of the substrate, the color filter is located between the first semiconductor layer and the pixel electrode, and the first semiconductor layer is electrically connected to the pixel electrode through a first connecting portion; the first connecting portion comprises a first connecting sub-portion in a first connecting hole and a first connecting electrode;
wherein an orthographic projection of the first connecting sub-portion on the plane of the substrate does not overlap with orthographic projection of the color filter on the plane of the substrate; and, along a direction parallel to the plane of the substrate, the first connecting sub-portion at least partially overlaps with the color filter;
wherein the array substrate further comprises a first light-blocking portion in the display region;
wherein the first light-blocking portion comprises a first light-blocking sub-portion extending along a first direction; the first light-blocking sub-portion is located between two adjacent color filters in a second direction; the first direction intersects with the second direction; and along the direction perpendicular to the plane of the substrate, the first connecting electrode does not overlap with the first light-blocking sub-portion; and
wherein the array substrate further comprises a first film layer; the first film layer comprises a first portion and a second portion that are insulated from each other; the first portion comprises the first light-blocking sub-portion; and the second portion comprises the first connecting electrode.
