10 is a cross-sectional view of one side of two displays adjacent to each other.

When two or more displays are adjacent to each other, the seam, which is a non-display area, must be minimized to have the same effect as viewing a single screen. In the LCD, which is one of the flat panel displays, two substrates composed of an upper plate 15 and a lower plate 17 are assembled to face each other, and a transparent electrode 19 is coated on the surface of the substrate. The liquid crystal layer 23 is disposed between the two transparent electrodes 19, and polarizing plates 15 ′ and 17 ′ are attached to the outside of the substrate.

This cross section is a conceptual diagram and is irrelevant to its actual size. For example, the electrode 19 coated on the lower plate 17 represents the width of the electrode on the drawing, the actual width of the electrode is much smaller, and the number is larger than that shown in the drawing. In addition, when the flat panel display is an EL element, there may be one substrate, an organic light emitting layer is present in place of the liquid crystal layer, and the polarizing plate is not used. In the present embodiment, as an embodiment for reducing the seam, the LCD is described as an example.

As shown in FIG. 10, in order to assemble the upper plate 15 and the lower plate 17 and seal the liquid crystal layer 23, sealants 24a and 24b are required. At this time, the sealant 24a of the joint portion 2 'is located immediately adjacent to the pixel electrode 19, but the sealant 24b of the non-seam portion is positioned away from the pixel electrode by a predetermined distance.

The seam sealant 24a should be as small as possible, for example within 0.8 mm. In addition, the side protective film 20c is attached directly to the outside of the joint sealant 24a (when the display is incorporated in the chassis 16, the side protective film 20c becomes the chassis 16 in the drawing). When attaching the side protective film 20c to the side of the display, an adhesive or the like may be used. At this time, the thickness of the side protective film 20c is also as small as possible, for example, within 0.8 mm. Therefore, in the present invention, when two or more flat panel displays are adjacent to form one screen, the non-display area of the seam is within 3.2 mm, so that the two screens are adjacent to each other and have the same effect as viewing one screen. do.

11 is a plan view when one side of two displays is adjacent to each other.

In FIG. 11, it can be seen that the sealants 24a and 24b printed on the display 2 and 4 adjacent to one side are biased toward the joint 2 '. This is to minimize the non-display area at the seam 2 '. In the drawing, an enlarged view of the seam is provided, and the seam sealant 24a is positioned immediately adjacent to the pixel electrode 19, and the side protection film 20c is in close contact with the outside of the seam sealant 24a.

By placing the display provided in the main body panel housing and the other panel housing which can be combined and separated on the upper side of at least one side of the panel housing, when the panel housing is coupled, one side of the display is effectively adjacent to each other.

In addition, by attaching a side protective film on the side of the display seam, it provides stable reliability to the display while minimizing the non-display area, and can be stably mounted to the panel housing through the fixing member provided in the chassis and the support member.
