Large-sized display apparatus and display device and display module used in large-sized display apparatus

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.
