The utility model discloses a medium and large size display device, which is characterized in that an optical adhesive layer is arranged between a cover plate and a display screen, at least one extension part is arranged on the optical adhesive layer, and the extension part is positioned between the cover plate and a backlight module, so that the display screen is prevented from being separated from the backlight module due to overweight of the backlight module; the problem to be solved is that the periphery of a display screen and the periphery of a backlight module of an existing display device are connected through shading glue. In a middle-large size display device, a backlight module is heavy due to the fact that a metal frame is thick, and separation of a display screen and the backlight module is easily caused by vibration or a reliable roller drop test in the transportation process. 本实用新型公开了一种中大尺寸的显示装置，通过在盖板与显示屏之间设置光学胶层，并在所述光学胶层上设置至少一个延伸部，所述延伸部位于所述盖板与背光模组之间，避免因背光模组过重，造成显示屏与背光模组分离；解决的问题是，现有的显示装置在显示屏与背光
