In the embodiment of the present application, the display device further includes a housing 60, where the housing 60 is matched with the cover plate 54 to cover the array substrate 10 and the motherboard 30, and specifically, the housing 60 is further used to cover the light emitting device (not shown), the encapsulation layer 51, the polarizer 52 and the buffer layer 53. In the embodiment of the present application, the main board 30 is fixed on the inner wall of the housing 60. The foregoing is a specific example of an embodiment of the present application, and the embodiment of the present application does not specifically limit the specific structure of the display device.
The foregoing is only the embodiments of the present application, and therefore, the patent scope of the application is not limited thereto, and all equivalent structures or equivalent processes using the descriptions of the present application and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the application.
