1. A display panel, comprising:
an array substrate having a display area and a frame area disposed around the display area, at least part of the frame area on a side of the display area serving as a bonding area, and the bonding area of the array substrate being provided therein with a ground terminal;
an opposite substrate opposite to the array substrate, an orthographic projection of the opposite substrate on the array substrate being not overlapped with the bonding area, the opposite substrate comprising a black matrix disposed on a side of the opposite substrate facing the array substrate, and a transparent conductive layer disposed on a side of the opposite substrate away from the array substrate, the black matrix comprising a first part, a second part and an isolation trench, the first part, the isolation trench and the second part being sequentially disposed in a direction from the display area to the bonding area, and the isolation trench isolating the first part from the second part;
a conductive adhesive connecting the ground terminal with the transparent conductive layer, a part of the conductive adhesive being filled between the array substrate and the opposite substrate, and an orthographic projection of the part of the conductive adhesive on the array substrate being not overlapped with an orthographic projection of the first part on the array substrate; and
a blocking structure filled between the array substrate and the opposite substrate, the blocking structure being in contact with the part of the conductive adhesive and configured for preventing the conductive adhesive, before being cured, from overflowing into a region where the first part is located,
wherein the opposite substrate comprises a first side surface adjacent to the bonding area,
the isolation trench comprises a first isolation sub-trench parallel to the first side surface, and a second isolation sub-trench and a third isolation sub-trench which extend to the first side surface respectively from two ends of the first isolation sub-trench,
wherein an orthographic projection of the blocking structure on the array substrate covers at least an orthographic projection of the first isolation sub-trench on the array substrate.
