The problem that the display device is aged and failed due to the fact that water and oxygen enter the display device from the end of the hole digging area exists in the display device. In one embodiment, the difference between the elastic modulus of the adhesive layer and the elastic modulus of the first adhesive layer is less than a threshold value. Through making the elastic modulus of bond line and the similar or even equal of elastic modulus of first tie coat, make when display device is crooked, the hole shape that digs that the dislocation of each rete that the bond line can adapt to display device leads to warp, make the bond line fill all the time in the via hole, and the bond line is laminated with the tip of each rete all the time, thereby avoid the invasion of water oxygen to lead to display device's ageing inefficacy in rete edge, and bond line and tie coat tip contact, can avoid the excessive glue that the bond line leads to because of dislocation many times.
The threshold value may be set as required so that the adhesive layer and the adhesive layer can be held in contact with each other by bending the adhesive layer and the adhesive layer accordingly. In one embodiment, the bond layer has a modulus of elasticity at 20 degrees celsius of less than or equal to 100 megapascals when the bond layer is solid.
In one embodiment, a projection of the adhesive layer on the cover plate when the display device is in the unfolded state is not coincident with a projection of the adhesive layer on the cover plate when the display device is in the bent state. Through making the bond line at display device bending process, the bond line can change along with the change of via hole, then the bond line can keep filling in the via hole, avoids dust and water oxygen invasion, and the tip contact of bond line and each rete, avoids display device to appear spilling gluey.

In one embodiment, the cover plate includes an ink layer, and a projection of the ink layer on a plane of the display panel is not coincident with a projection of the adhesive layer on the plane of the display panel. The projection of the ink layer and the projection of the bonding layer are not overlapped, so that the curing effect is better when the bonding layer is cured.
In one embodiment, the cover plate includes an ink region, and the ink region and the electronic component disposing region have an overlapping portion. When the ink area is arranged, the ink area can be extended to the electronic element arrangement area, so that the interference of the light of the display area to the light of the electronic element arrangement area is avoided, and the edge of the via hole is shielded.
