Also as shown in FIG. 1 and FIG. 2, the arm unit 200 is arranged tilted toward the back side of the display displaying unit 300 from the rear of the body stand unit 100. In FIG. 2, a tilt angle 8 of the arm unit 200 with respect to a perpendicular direction is a value about 45.degree. to 60.degree.. Because of this, when the display displaying unit 300 is seen from the front, the arm unit 200 is hidden behind the display displaying unit 300, so that the user's recognition of the arm unit 200 can reliably be suppressed. Therefore, the arm unit 200 can be reliably suppressed from being recognized within the view of the user due to a synergetic effect with the arrangement of the arm unit 200 shifted from the center of the display displaying unit 300.
FIG. 4 is exemplary diagrams showing the configuration of the arm unit 200 in detail. Here, FIG. 4a shows a front view of the arm unit 200 seen from the front of the display displaying unit 300, FIG. 4B shows a left side view, FIG. 4C shows a right side view, FIG. 4D shows a top view, FIG. 4E shows a bottom view, FIG. 4F shows a rear view, and FIG. 4G shows a cross-sectional view taken along a chain line I-I' in FIG. 4C, respectively. The body of the arm unit 200 with the cover 240 detached therefrom can be configured as a single block made of metal such as aluminum being casted or ground.
Furthermore, FIG. 5 is exemplary diagrams showing a configuration of the cover 240 in detail.

As shown in FIG. 5, the cover 240 is provided with a concave part 242, and is configured such that the side walls 242a on both sides of the concave part 242 fit into the side surfaces in the width direction of the first arm unit 210. The flexible printed circuit substrates 250 are arranged between the first arm unit 210 and the cover 240 in a state of being accommodated at the bottom of the concave part 242. Therefore, the flexible printed circuit substrates 250 are not exposed to the external appearance.
Furthermore, FIG. 9 is exemplary diagrams showing a configuration of the T-cover 430. Here, FIG. 9A shows a front view of the T-cover 430 seen from the front of the display displaying unit 300, FIG. 9B shows a left side view, FIG. 9C shows a right side view, FIG. 9D shows a top view, FIG. 5E shows a bottom view, FIG. 9F shows a rear view, and FIG. 9G shows a cross-sectional view taken along a chain line III-III' in FIG. 9A, respectively.
FIG. 14 is exemplary diagrams showing a configuration of the shaft 366 in detail. Here, FIG. 14A shows a front view of the shaft 366 seen from the back side of the display displaying unit 300, a right side view, and a left side view, respectively. Furthermore, FIG. 14B shows a cross section taken along the central axis of the shaft 366. Furthermore, FIG. 14C shows a cross section taken along a chain line IV-IV' in FIG. 14A.
Here, the angular range between the two end surfaces 362e of the concave part 362d of the first hinge plate 362 and the angular range between the two end surfaces 364e of the concave part 364d of the second hinge plate 364 are the same. As shown in FIG. 14A, the engagement grooves 368f and 370f which determine the angular positions of the lock position determining plates 380 are located at the same angular positions with respect to the central axis of the shaft 366, by the relative angular positions of the shaft 368 and the shaft 370 being determined by the pins 369. Therefore, the angular position of the projection part 380c with respect to the two end surfaces 362e of the concave part 362d is the same as the angular position of the projection part 380c with respect to the two end surfaces 364e of the concave part 364d. Therefore, as shown in FIG. 17A and FIG. 17B, when the tilt of the display displaying unit 300 is moved upward, assuming that the movable angle of the first hinge plate 362 is .alpha.ll and the movable angle of the second hinge plate 364 is .alpha.12, the relation .alpha.11=.alpha.21 holds. Furthermore, when the tilt of the display displaying unit 300 is moved downward, assuming that the movable angle of the first hinge plate 362 is .alpha.12 and the movable angle of the second hinge plate 364 is .alpha.22, the relation .alpha.12=.alpha.22 holds.

Here, FIG. 18A shows a cross section taken along the central axis of the shaft 366. Furthermore, FIG. 18B is an exemplary diagram showing a cross section taken along a chain line V-V' in FIG. 18A. In the example of FIG. 18, the engagement shaft 368d of the shaft 368 is inserted into a hole 370h of the shaft 370, and a key 370i of the hole 370h is engaged with a key groove 368g of the engagement shaft 368d, so that the angular position of the shaft 368 and the shaft 370 is determined. The shaft 368 and the shaft 370 are configured by a caulking pin 367 for fixing being caulked into the shaft 370, so that the shaft 368 does not come off from the shaft 370. According to such a configuration as well, the angular position of the engagement groove 368f of the shaft 368 and the engagement groove 370f of the shaft 370 can be determined, and the positions where the tilt position is locked can be the same between the first hinge plate 362 and the second hinge plate 364.
As shown in FIG. 20, the flexible printed circuit substrates 450 pulled out from the upper end of the organic EL panel 320 are folded back by 180.degree., and are connected to the T-substrate 350. Furthermore, the flexible printed circuit substrates 460 pulled out from the lower end of the organic EL panel 320 are folded back by 180.degree. and are connected to the T-substrate 350. Therefore, the T-substrate 350 is not necessarily arranged on the entire surface of the organic EL panel 320 at the rear of the organic EL panel 320, and the occupied region by the T-substrate 350 can be suppressed to the minimum.
Furthermore, the flexible printed circuit substrates 450 and 460 pulled out from the T-substrate 350 are folded back by 180.degree. and are connected to the organic EL panel 320, and thereby electrical connection between the organic EL panel 320 and the T-substrate 350 can be performed without expanding the external form of the organic EL panel 320. Therefore, according to the substrate wiring structure of the display displaying unit 300 of the present embodiment, the size of the display displaying unit 300 can be suppressed to the minimum, and there can be achieved the miniaturization of the display displaying unit 300.
FIG. 21 is an exemplary diagram showing the display displaying unit 300 in FIG. 20 seen from the back side thereof. As shown in FIG. 21, a plurality of flexible printed circuit substrates 460 pulled out from the lower end of the organic EL panel 320 are folded back by 180.degree. and are connected to the T-substrate 350, so that the driver ICs 470 are arranged in the straight line in a horizontal direction. The drivers IC 470 are arranged near the shaft 366 along the extending direction of the shaft 366.
FIG. 23 is an exemplary diagram showing a cross-sectional configuration of the upper part of the display displaying unit 300. As shown in FIG. 23, a plurality of flexible printed circuit substrates 450 pulled out from the upper end of the organic EL panel 320 are folded back by 180.degree., and are led to the T-substrate 350 on the lower side in the state being adhered to the rear cover 420. The graphite sheet 330 is attached to the front of the back surface of the organic EL panel 320, and the flexible printed circuit substrates 450 are located between the graphite sheet 330 and the rear cover 420.
