1. A display panel, wherein the display panel is provided with a preset area, a transmitting sensor and a receiving sensor of a time-of-flight device are adapted to be provided on a non-display side of the preset area, and light emitted from the transmitting sensor is adapted to be transmitted from the preset area to a display side of the display panel, and be reflected by a to-be-detected object on the display side back to a non-display side of the display panel, so as to be received by the receiving sensor, the display panel comprising:
a substrate layer;
an organic light-emitting device layer provided on a display side of the substrate layer; and
an anti-reflection layer comprising one or more anti-reflection layers and provided between the substrate layer and the organic light-emitting device layer, at least part of the anti-reflection layer being disposed opposite to the preset area in a thickness direction of the display panel, wherein at least one of the one or more anti-reflection layers is made of polyimide.
