FIG. 10is a view illustrating a multi display device according to the second embodiment of the present invention, andFIG. 11is a cross-sectional view illustrating a section taken along line V-V′ shown inFIG. 10and illustrates that the aforementioned display devices according to one embodiment of the present disclosure are connected with each other up and down. Therefore, the same reference numbers will be used throughout the drawings to refer to the same or like parts, and repeated description in material and structure of each element will be omitted.

Referring toFIGS. 10 and 11, the multi display device according to the second embodiment includes a first display module DM1, a second display module DM2, and a connection member700.

The side cover film900is attached to one side of the first display module DM1, and has a plurality of guide holes910respectively overlapped with the plurality of guide protrusions500provided at one side of the panel support frame.

A plurality of auxiliary side cover films950are attached to a side of the second display module DM2, and each of the plurality of auxiliary side cover films950has a plurality of auxiliary guide holes960respectively overlapped with the plurality of guide protrusions500additionally provided at the other sides except one side of the panel support frame200.

The first display module DM1and the second display module DM2are coupled to each other up and down. Therefore, each of the guide holes910of the first display module DM1and each of the auxiliary guide holes960are arranged to face each other.

The connection member700connects the first display module DM1and the second display module DM2with each other. The connection member700is inserted into the guide protrusions500provided in each of the first display module DM1and the second display module DM2.

Since the guide protrusions500are provided in each of the first display module DM1and the second display module DM2, the first display module DM1and the second display module DM2may easily be coupled to each other even without separate alignment.

FIG. 12is a brief view illustrating a multi display device according to the third embodiment of the present disclosure, and illustrates that the aforementioned display devices according to one embodiment of the present invention are connected with each other up and down and from side to side. Therefore, a cross-sectional view taken along line IV-IV′ shown inFIG. 12is the same as that of the multi display device according to the first embodiment of the present disclosure described with reference toFIG. 9, and a cross-sectional view taken along line V-V′ shown inFIG. 12is the same as that of the multi display device according to the second embodiment of the present invention described with reference toFIG. 11. Therefore, the same reference numbers will be used throughout the drawings to refer to the same or like parts, and repeated description in material and structure of each element will be omitted.

Referring toFIG. 12, the multi display device according to the third embodiment includes a first display module DM1, a second display module DM2, a third display module DM3, a fourth display module DM4, and a connection member700.

The first display module DM1is coupled to the second display module DM2from side to side, and is coupled to the third display module DM3up and down. In this case, the connection member700is provided between the first display module DM1and the second display module DM2to connect the first display module DM1with the second display module DM2. Also, the connection member700is provided between the first display module DM1and the third display module DM3to connect the first display module DM1with the third display module DM3.

The second display module DM2is coupled to the fourth display module DM4up and down. In this case, the connection member700is provided between the second display module DM2and the fourth display module DM4to connect the second display module DM2with the fourth display module DM4.

The third display module DM3is coupled to the fourth display module DM4from side to side. The connection member700is provided between the third display module DM3and the fourth display module DM4to connect the third display module DM3with the fourth display module DM4.

In this specification, although the present disclosure has been described based on the liquid crystal display device as an example, the present disclosure is not limited to the liquid crystal display device and may be applied to various display devices, for example, an organic light emitting display device.

According to the present disclosure, the following advantages can be obtained.

Since the flexible circuit films are attached to one side of the display panel, it is not required to externally expose the signal line unlike the related art. Therefore, the bezel area may be reduced as compared with the display device of the related art.

Also, since the plurality of guide protrusions guide the attachment position of the protective film and the side cover film, attachment accuracy of the protective film and the side cover film may be improved. Also, after the cover shield is primarily fixed to the panel support frame by the plurality of guide protrusions, the cover shield and the panel support frame are assembled to each other. Therefore, distortion of the cover shield, which is caused during the assembly process may be avoided. As a result, assembly accuracy of the cover shield may be improved.
