In this way, the display substrate 1 can be deformed, and the display substrate can be bonded to the cover plate 2 better.
In one embodiment of the present disclosure, as shown in fig. 1, the front projection of the display substrate 1 in the first direction X may be located within the front projection of the cover plate 2 in the first direction X. The first direction X may be a direction in which the cover plate 2 points toward the display substrate 1. By the arrangement, the cover plate 2 can be utilized to protect the display substrate 1, so that the situation that the display substrate 1 cannot be completely covered due to too small cover plate 2 is avoided, and the probability of damage of the display substrate 1 in the using process can be reduced.
The inventor of the present disclosure has invented a display device in addition to the display panel described above. The display device may include the above-described display panel, and as shown in fig. 1 to 7, the display device may ensure that the first cambered surface 11 and the second cambered surface 21 in the display panel may be tightly attached. Therefore, the problem that the first cambered surface 11 is inconsistent with the second cambered surface 21 in radius and the lamination is not tight in the lamination process can be prevented, the display device can be guaranteed to have a good display effect, a user can have a better visual effect when watching the image displayed by the display device, and the watching experience of the user can be improved.
It should be noted that, the structure and the beneficial effects of the display panel have been described in detail in the above subject matter, so that the structure and the beneficial effects of the display panel are not described in detail in the present subject matter, and reference may be made to the specific description of the display panel in the above subject matter, which is within the scope of protection of the present disclosure.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This disclosure is intended to cover any adaptations, uses, or adaptations of the disclosure following the general principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the disclosure being indicated by the following claims.
