As shown in FIG. 3, first terminal part 4 and second terminal part 5 respectively includes a plurality of connectors 6. First terminal part 4 and second terminal part 5 are disposed in openings 3b of an end surface of swelling 3a of back cover 3 such that first terminal part 4 and second terminal part 5 are adjacent to each other. The connectors of first terminal part 4 and second terminal part 5 function as input/output terminals and control terminals of the display device, and the connectors are compatible with USB terminals, HDMI (registered trademark) terminals, D terminals, optical terminals, headphone terminals, LAN terminals, antenna terminals for broadcast wave such as ground wave, BS and CS, analogue input/output terminals, and card sockets into which IC cards and memory cards are inserted. Connection cable 7 is attached to each of connectors 6 for electrical connection with an external device.
As shown in FIGS. 3 and 4, first terminal part 4 and second terminal part 5 are configured by electrically and mechanically connecting the plurality of connectors 6 to wiring parts (not shown) of square substrate 8 of an input/output circuit block mounted on chassis 1b of display panel 1. That is, the plurality of connectors 6 of first terminal part 4 are connected to an end of one side of substrate 8 in a state where connectors 6 are arranged in a line, and the plurality of connectors 6 of second terminal part 5 are connected to an end of another side of substrate 8 which is adjacent to the former side in a state where connectors 6 are arranged in a line.
First terminal part 4 and second terminal part 5 respectively include first and second support tools 10 and 11 which are machined metal products or molded resin products called brackets. First and second support tools 10 and 11 respectively include openings 9 through which connection cables 7 can be attached to connectors 6. First and second support tools 10 and 11 of first terminal part 4 and second terminal part 5 are disposed on front sides of connectors 6 provided with connecting parts to which connection cables 7 are connected. First and second support tools 10 and 11 are mounted on chassis 1b together with substrate 8 such that first and second support tools 10 and 11 close openings 3b of swelling 3a of back cover 3.
According to this, in first terminal part 4 and second terminal part 5, connectors 6 are exposed outside through openings 9 of first and second support tools 10 and 11 so that connection cables 7 can be attached to connectors 6. Connectors 6 are disposed at such distances from one another that connection cables 7 do not interfere with each other when connection cables 7 are attached to connectors 6 through openings 9 of first and second support tools 10 and 11. FIG. 4 shows a state where one end of second support tool 11 is detached.
FIG. 5 is a perspective view showing a configuration of a chassis part of the display device on which the terminal parts are disposed. FIG. 6 is an enlarged perspective view of part A in FIG. 4. FIG. 7 is an enlarged perspective view of part B in FIG. 4. FIG. 8 is a sectional view taken along line 8-8 in FIG. 6. FIG. 9 is a sectional view taken along line 9-9 in FIG. 7.
As shown in FIG. 5, a plurality of (four in the drawing) cylindrical mounting parts 12a, 12b, 12c, and 12d are provided on chassis 1b at locations where substrate 8 and first and second support tools 10 and 11 are mounted. Substrate 8 and first and second support tools 10 and 11 are mounted on mounting parts 12a, 12b, 12c, and 12d through screws 13. Of mounting parts 12a, 12b, 12c, and 12d, mounting part 12a is disposed at a location corresponding to a corner part where two sides of substrate 8 on which connectors 6 are disposed intersect with each other.
As shown in FIGS. 6 to 9, both ends of first support tool 10 of first terminal part 4 are respectively provided with first and second mounting pieces 10a and 10b. First and second mounting pieces 10a and 10b are superposed on an upper side of substrate 8, and are mounted on mounting parts 12a and 12b through screws 13 together with substrate 8. According to this, first support tool 10 is fixed to mounting parts 12a and 12b together with substrate 8.
On the other hand, second support tool 11 of second terminal part 5 is provided at its both ends with first and second mounting pieces 11a and 11b. First mounting piece 11a is disposed such that it is superposed on a lower side of substrate 8, and is mounted, through screw 13, on mounting part 12a on which first mounting piece 10a of first support tool 10 is mounted. Second mounting piece 11b is superposed on the upper side of substrate 8, and is mounted on mounting part 12c through screw 13. According to this, second support tool 11 is fixed to mounting parts 12a and 12c together with substrate 8. First mounting piece 11a of second support tool 11 has a difference in level with respect to second mounting piece 11b, and first mounting piece 11a is located lower than second mounting piece 11b. 
As a structure for mounting first mounting piece 11a on mounting part 12a, it is possible to employ a structure in which first mounting piece 11a is sandwiched between mounting part 12a and substrate 8, thereby fixing first mounting piece 11a to mounting part 12a, and a structure in which first mounting piece 11a is sandwiched between chassis 1b and substrate 8 with a washer interposed therebetween, thereby fixing first mounting piece 11a to mounting part 12a. 
FIG. 10 is a perspective view showing one example of the support tool of the second terminal part. As shown in FIG. 10, in second support tool 11 of second terminal part 5, first mounting piece 11a which is mounted on mounting part 12a together with first mounting piece 10a of first support tool 10 has a substantially U-shaped hole formed by notching a part of a hole through which screw 13 penetrates. As described above, first mounting piece 11a of second support tool 11 has the difference in level with respect to second mounting piece 11b, and first mounting piece 11a is located lower than second mounting piece 11b. 
Therefore, when second support tool 11 is mounted, substrate 8 and first mounting piece 10a of first support tool 10 are firstly positioned with respect to mounting part 12a, and then U-shaped first mounting piece 11a of second support tool 11 is hitched to a lower side of substrate 8 of mounting part 12a. Then, second mounting piece 11b is positioned such that second mounting piece 11b comes to the upper side of substrate 8 with respect to mounting part 12c as shown by an arrow in FIG. 10, thereby mounting second support tool 11.
FIG. 11 is a perspective view showing another example of the support tool of the second terminal part. In the example shown in FIG. 11, a hole of first mounting piece 11a through which screw 13 penetrates is circular. Like the previously described examples, first mounting piece 11a has the difference in level with respect to second mounting piece 11b, and first mounting piece 11a is located lower than second mounting piece 11b. That is, in the example shown in FIG. 11, first mounting pieces 10a and 11a and second mounting pieces 10b and 11b of first support tool 10 and second support tool 11 have circular holes.
In the case of second support tool 11 shown in FIG. 11, after first mounting piece 11a of second support tool 11, substrate 8, and first mounting piece 10a of first support tool 10 are positioned with respect to mounting part 12a in this order, second support tool 11 is fixed through screws 13. When first mounting piece 11a is positioned with respect to mounting part 12a, second mounting piece 11b may be positioned with respect to mounting part 12c at the same time or may be positioned later as shown in the example in FIG. 10.
As described above, the display device according to the present technique includes first terminal part 4 configured by arranging a plurality of connectors 6 on the end of one side of substrate 8, and second terminal part 5 configured by arranging a plurality of connectors 6 on an end of another side of substrate 8 which is adjacent to the former side of substrate 8. The display device includes: first support tool 10 disposed on first terminal part 4, and provided with openings 9 through which connection cables 7 can be attached respectively to connectors 6, and also provided with first mounting piece 10a and second mounting piece 10b to be mounted on mounting parts 12a and 12b; and second support tool 11 disposed on second terminal part 5, and provided with openings 9 through which connection cables 7 can be attached respectively to connectors 6, and also provided with first mounting piece 11a to be mounted on mounting part 12a on which first mounting piece 10a of first support tool 10 is mounted and with second mounting piece 11b to be mounted on mounting part 12c. 
According to this, first mounting piece 10a of first support tool 10 and first mounting piece 11a of second support tool 11 are mounted on common mounting part 12a, and mounting part 12a is provided at a position corresponding to a corner part of substrate 8. According to this configuration, connectors 6 can be disposed also in the vicinity of the corner part of substrate 8, and the plurality of connectors 6 can efficiently be disposed in a region having a small part.
Substrate 8 on which connectors 6 are disposed is also mounted on mounting parts 12a, 12b, and 12c on which first support tool 10 and second support tool 11 are mounted. According to this, it is possible to configure the terminal part with a simple structure.
Further, since first mounting piece 11a and second mounting piece 11b of second support tool 11 are different from each other in level, it is possible to prevent mounting pieces from interfering with each other when first mounting piece 10a of first support tool 10 and first mounting piece 11a of second support tool 11 are mounted on common mounting part 12a. 
Since first mounting piece 11a of second support tool 11 has substantially the U-shaped hole formed by cutting away a part of a hole, the operation for mounting second support tool 11 can easily be carried out.
In the above embodiment, a plurality of mounting parts including mounting part 12a provided at a position corresponding to the corner part where two sides of substrate 8 on which connectors 6 are disposed intersect with each other are provided on chassis 1b. However, when mounting parts on which substrate 8 is mounted and mounting parts on which first and second support tools 10 and 11 are mounted are separately provided, it is not absolutely necessary that the mounting parts are provided on chassis 1b, and the mounting parts on which first and second support tools 10 and 11 are mounted may be provided on back cover 3. Thus, it is only necessary that first mounting piece 10a of first support tool 10 and first mounting piece 11a of second support tool 11 are mounted on common mounting part 12a, and mounting part 12a is provided at a position corresponding to a corner part of substrate 8.
Further, in the above embodiment, a plurality of connectors 6 of first terminal part 4 are connected in the state where connectors 6 are arranged in a line on an end of one side of one square substrate 8, and a plurality of connectors 6 of second terminal part 5 are connected in the state where connectors 6 are arranged in a line on an end of another side adjacent to the one side of substrate 8. However, in addition to the configuration that connectors 6 are disposed on two sides of substrate 8, it is possible to employ a configuration that connectors 6 are disposed on three sides, and the shape of substrate 8 may be of a polygonal shape other than the square shape. The number of substrate 8 is not limited to one, and two or more substrates 8 may be used.
Furthermore in the above embodiment, although first mounting piece 11a and second mounting piece 11b of second support tool 11 are different from each other in level, first mounting piece 10a and second mounting piece 10b of first support tool 10 may also be different from each other in level. That is, the first mounting piece and the second mounting piece of at least one of first support tool 10 and second support tool 11 may be different from each other in level.
Although first mounting piece 11a of second support tool 11 has substantially the U-shaped hole formed by cutting away a part of a hole in the above embodiment, first mounting piece 10a of first support tool 10 may also have substantially a U-shaped hole formed by notching a part of a hole. That is, the first mounting piece of at least one of first support tool 10 and second support tool 11 may have substantially a U-shaped hole formed by notching a part of a hole.
As described above, the embodiment is described as an example of the technique in this disclosure. For this purpose, the accompanying drawings and the detailed description are provided.
Therefore, not only the indispensable configuration elements for solving the problem but also configuration elements which are not indispensable for solving the problem are included in the configuration elements illustrated and described in the accompanying drawings and the detailed description for exemplifying the technique. Hence, although the configuration elements which are not indispensable are illustrated and described in the accompanying drawings and the detailed description, it should not immediately be recognized that the configuration elements which are not indispensable are indispensable.
Since the above embodiment is for exemplifying the technique in this disclosure, the embodiment can variously be modified, replaced, and omitted or other elements can be added within claims or in a scope equal to claims.
