Abstract: A protective measure against rainfalls or ultraviolet rays is applied to planar display devices which comprise a large-sized display apparatus thus allowing display modules which include display devices to be used outdoors and, at the same time, the structure of a frame is simplified thus realizing the reduction of weight, thickness and a manufacturing cost of the large-sized display apparatus. In a large-sized display apparatus arranging a plurality of planar display devices, as the planar display device, a display device which comprises a display device body which includes a display region in the inside thereof and has a peripheral portion of the display region sealed, and a protective glass which is fixedly mounted on a front surface of the display device body using an adhesive material is used.

Abstract: The present invention provides a display device which includes at least one module mounting frame which is mounted on a display device mounting structure, a plurality of display modules which are detachably mounted on the module mounting frame and constitute a display screen, a signal cable which has a wiring route in the inside of the module mounting frame and is detachably connected to the display modules and supplies image signals to the display modules, and a power source cable which has a wiring route in the inside of the module mounting frame and is detachably connected to the display modules thus supplying electric power to the display modules. Due to such a constitution, it is possible to realize the reduction of weight and the lowering of the manufacturing cost.
