1. A display panel, comprising:
a substrate having an opening area, a transition area surrounding the opening area, and a display area surrounding the transition area;
a drive layer provided on a side of the substrate and covering the display area and the transition area, wherein a portion of the drive layer is located in the transition area comprises a light reflective layer surrounding the opening area;
an isolation column arranged on a surface of a boss of the drive layer facing away from the substrate and located in the transition area, wherein the isolation column surrounds the opening area, a contour line of a projection of the isolation column on the substrate is located within a contour line of a projection of the light reflective layer on the substrate, and the isolation column is used to partition the light emitting layer; and a side wall of the isolation column is provided with a groove;
a light emitting device layer covers the drive layer and the isolation column, wherein the light emitting device layer comprises a light emitting layer, and the light emitting layer is discontinuous at the groove; and
a through hole penetrating the drive layer and the light emitting device layer and located in the opening area;
wherein in a direction perpendicular to the substrate, the light reflective layer in the portion of the drive layer corresponding to the isolation column comprises an upper light reflective layer and a lower light reflective layer;
the drive layer comprises a thin film transistor and a capacitor electrode in the display area, and a gate of the thin film transistor and the capacitor electrode form a storage capacitor;
the gate and the lower light reflective layer are arranged in a first layer, the capacitor electrode and the upper light reflective layer are arranged in a second layer, and a source and a drain of the thin film transistor and the isolation column are arranged in a third layer and
wherein a distance between the contour line of the projection of the light reflective layer on the substrate and the contour line of the projection of the isolation column on the substrate is greater than 1 μm.
