In the embodiment of fig. 11, the vertical projection of the first magnetic structure 1051 on the plane of the first substrate 1011 does not overlap with the edge of the vertical projection of the opening area 104 on the plane of the first substrate 1011, and the vertical projection of the second magnetic structure 1052 on the plane of the first substrate 1011 does not overlap with the edge of the vertical projection of the opening area 104 on the plane of the first substrate 1011. As shown in fig. 11, the vertical projection of the first magnetic structure 1051 on the plane of the first substrate 1011 does not overlap with the edge of the vertical projection of the opening 104 on the plane of the first substrate 1011, so that the interference of the magnetic field effect of the first magnetic structure 1051 on the display area on the side of the array substrate 101 can be reduced, for example, the interference of the shielding on the driving circuit can be reduced, and the display effect of the display panel can be ensured. As shown in fig. 12, the perpendicular projection of the second magnetic structure 1052 on the plane of the first substrate 1011 does not overlap with the edge of the perpendicular projection of the opening area 104 on the plane of the first substrate 1011, so that the interference of the second magnetic structure 1052 on the display area on the side of the opposite substrate 102 can be reduced, for example, the interference on the common electrode disposed in the opposite substrate 102 is shielded, and the display effect of the display panel is ensured.
