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.

Claims15

Dependent claims

A large-sized display apparatus comprising a frame and at least first and second separate planar display devices mounted on the frame to compose together a large-sized display, wherein:

said first planar display device includes:
a first display device body having only one first display region which is sealed around its outer periphery, and
a first protective glass member mounted directly to the first display device body in front of the first display region;
and
said second planar display device spaced from said first planar display device and including:
a second display device body, separate from said first display device body, and having only one second display region which is sealed around its outer periphery, and
a second protective glass member, separate from said first protective glass member, mounted directly to the second display device body in front of the second display region, wherein an edge of the second display device is superposed in front of the first display device.
