When the display device 1 of the present embodiment in which the display main body 10 is held in a standing posture by the stand member 30 is installed outdoors, the display device 1 is exposed to rain outdoors. As shown in FIG. 2, in the display body 10 whose outer surface is covered with two cover frame members 13, there is a slight gap between the two C-shaped cylindrical portions 132 connected to the two opening / closing shafts 181. There is a gap in And this clearance gap may become an entrance of water, such as rain water, outdoors. When the water so infiltrated adheres to the light emitting surface, the positive image film, or the like, the display quality in the display device may deteriorate.

In this embodiment, first, the packing 40 is installed between the gap between the two C-shaped cylindrical portions 132 and the rectangular cylindrical portion 171 so as to close the entrance of water. The packing 40 is formed of a soft rubber sponge having a thickness of, for example, about 3 mm and crushing to about 0.4 mm when pressed. An example of this rubber sponge is rubber sponge E-4188 manufactured by Inoac Corporation. In the present embodiment, the packing 40 prevents water from entering from outside the frame, or suppresses the amount of water entering. Then, the water that has entered without being prevented by this packing 40 is drained by a simple drainage structure described below, and adhesion of such water to the light emitting surface or the like can be suppressed.

FIG. 8 is a diagram for explaining a drainage structure in the display device shown in FIGS. 1 and 2. As shown in FIG. 8, the rainwater R tries to enter from the gap between the two C-shaped cylindrical portions 132 as indicated by the arrow D1. This intrusion is first prevented by the packing 40 as described above. Then, the water that has entered without being prevented by the packing 40 once accumulates in the lower portion of the opening / closing shaft 181, and then enters the interior of the rectangular cylinder portion 171 from the gap between the hinge member 18 and the rectangular cylinder portion 171. It flows into the first drainage channel 174 as indicated by the arrow D2. Further, part of the water that has flowed into the first drainage channel 174 is, for example, a second drainage channel 179 provided outside the frame in the finding direction Ax1 in the wall 172 due to a gap between the hinge member 18 and the rectangular cylinder 171. Flows in as shown by the arrow D3. That is, two drainage channels are formed in the surface light emitting member frame member 17 to follow the following route.

FIG. 9 is a diagram schematically showing a drainage path in the display device shown in FIGS. 1 and 2. As shown in FIG. 9, in the surface light emitting member frame member 17, the infiltrated water passes through the first water channel 174a in the upper frame member 17a as indicated by the arrow D4. The left and right frame members 17b flow from side to side toward the first water channel 174a. Then, the left and right first water channels 174a flow downward toward the first water channel 174a of the lower frame member 17a as indicated by an arrow D5. Finally, it flows left and right through the first water channel 174a of the lower frame member 17a. At this time, as shown in FIG. 2, the first water channel 174a of the lower frame member 17a remains open. Therefore, the water flowing left and right in the lower first water channel 174a overflows from the opening and falls and is discharged to the outside from the drain port 134 shown in FIG.

Further, the water that has flowed from the first drainage channel 174 into the second drainage channel 179 in the upper frame member 17a also follows the paths indicated by arrows D4 and D5 in FIG. Here, the second water channel 179a in the lower frame member 17a opens downward as shown in FIG. For this reason, water falls as it is when it reaches the lower second water channel 179a, and is discharged to the outside from the drain port 134 shown in FIG.

As described above, according to the display device 1 of the first embodiment, even if water such as rainwater enters from a gap around the opening / closing shaft 181 in the hinge member 18, it is more than the edge of the surface light emitting member 16. Due to the simple structure of the wall portion 172 that is arranged outside the frame in the finding direction Ax1 and extends in the prospective direction Ax2, and the first and

second drainage channels

Further, in the display device 1, the transparent cover frame member 13 is arranged in parallel with the light emitting surface in the prospective direction with a space between the light emitting surface of the surface light emitting member 16 and the end of the surface light emitting member 16. It has an overhanging portion 131a that protrudes closer to the inside of the frame in the finding direction Ax1 than the edge. Here, in the surface light emitting member 16, light emission unevenness may occur at an end near the LED light source 15. According to the display device 1, even if such light emission unevenness occurs, the light emission unevenness is hidden by the transparent cover frame member 13 protruding as described above. Thereby, the display quality in the display apparatus 1 will improve.

Further, according to the display device 1, for example, the stored positive image film 12 can be prevented from being stolen by providing the lock member 14 that prohibits the opening and closing of the transparent cover 11.

Further, according to the display device 1, the packing 40 prevents water from entering from the outside of the frame, or suppresses the amount of intrusion. Thereby, the adhesion of water to the surface light emitting member 16 and the like is further suppressed.

Further, in this display device 1, a pair of first and

second drainage channels

174 and 179 are provided corresponding to the respective light emitting surfaces of the surface light emitting member 16. For this reason, even if water permeates from the vicinity of the opening / closing shaft 181 of the hinge member 18 on any light emitting surface side, the adhesion of water to each light emitting surface or the like is suppressed. As described above, according to the display device 1, in the display device 1 that emits and displays symbols on both the front and back surfaces using the surface light emitting member 16 that emits light from both sides, it is possible to suppress adhesion of water on any light emitting surface. .

It has become. In the surface light emitting member frame member 53, the first water channel 534a in each of the four frame members communicates in a frame shape to form a first drainage channel 534. Also in this embodiment, as in the first embodiment described above, the members forming the cover frame member 13 and the members forming the surface light emitting member frame member 53 are shown in FIG. They are connected by two connecting

fittings

175 and 176 and screws 177. The first water channel 534a is also used as an arrangement place for the two connecting

fittings

175 and 176.

The wall portion 532 is disposed outside the edge of the surface light emitting member 52 in the direction of Ax3, as shown in FIG. 11, with the surface light emitting member frame member 53 holding the back plate 54. It extends in the prospective direction Ax4. In addition, a protruding wall 535 protrudes from the surface of the wall portion 532 on the rectangular tube portion 531 side with a space between the opening of the rectangular tube portion 531 in the prospective direction Ax4. On the rectangular tube portion 531 side of the wall portion 532, a concave portion surrounded by the wall portion 532, the rectangular tube portion 531 and the protruding wall 535 extends in the longitudinal direction. This recessed portion serves as a second water channel 536a through which water that has entered the display main body 10 flows. In the surface light emitting member frame member 53, the second water channel 536a in each of the four frame members communicates in a frame shape to form a second drain channel 536.

The second drainage channel 536 is formed between the first drainage channel 534 and the wall portion 532 described above and substantially parallel to the first drainage channel 534 so as to be shifted to the outside in the prospective direction Ax4. Further, the wall portion 532 is formed to extend further outward in the prospective direction Ax4 than the second drainage channel 536.

The surface light emitting member holding portion 533 is a wall that protrudes from the rectangular tube portion 531 toward the inside of the frame in the finding direction Ax3, and the back plate 54 is bonded and fixed to the surface light emitting member holding portion 533. In addition, a back plate 54 is bonded and fixed to the surface light emitting member holding portion 533 with a spacing of 7.0 mm between the wall portion 532 and the LED case 55 in the finding direction Ax3.

Among the four frame members constituting the surface light emitting member frame member 53, the hinge member 18 is fixed to the rectangular cylinder portion 531 of the upper frame member when the display device 5 is in the standing posture. Each hinge member 18 corresponds to two C-shaped openings in the cross-sectional shape of the rectangular cylindrical portion 531 and extends in the longitudinal direction in the same manner as in the first embodiment described above, and includes two connecting

brackets

175 and 176 and screws 177. It is fixed using.

As shown in FIG. 10, when the display device 5 is installed on the outdoor wall W in a standing posture, the display device 5 is exposed to rain outdoors. As shown in FIG. 11, in the display device 5, the opening / closing shaft 181 and the periphery of the C-shaped cylindrical portion 132 connected to the opening / closing shaft 181 are substantially exposed. For this reason, water such as rainwater may enter the inside of the display device 5 from, for example, a gap between the surface light emitting member frame member 53 and the hinge member 18. When the water so infiltrated adheres to the light emitting surface, the positive image film, or the like, the display quality in the display device may deteriorate.

Also in the present embodiment, as in the first embodiment described above, the packing 41 is first installed between the C-shaped cylindrical portion 132 and the rectangular cylindrical portion 531 in order to close the water entrance. This packing 41 is also formed of a soft rubber sponge similar to the rubber sponge forming the packing 40 in the first embodiment. In the present embodiment, the packing 41 prevents water from entering from outside the frame, or suppresses the amount of water entering. Then, the water that has entered without being prevented by the packing 41 is drained by the simple structure of the wall portion 532 and the first and second drainage channels 534, 536, and such water Is prevented from adhering to the light emitting surface.

In addition, the drainage structure which consists of the 1st and 2nd drainage channel 534,536 in this embodiment is the drainage which consists of the 1st and 2nd drainage channel 174,179 in 1st Embodiment demonstrated with reference to FIG. It is almost equivalent to the structure. That is, the water that has entered without being prevented by the packing 41 flows into the first drainage channel 534 as described above. Further, a part of the water accumulated in the first drainage channel 534 flows into the second drainage channel 536 through a gap between the hinge member 18 and the rectangular cylinder part 531 or the like.

Also, the drainage path in the display device 5 of the present embodiment is substantially the same as the drainage path in the first embodiment described with reference to FIG. In other words, the infiltrated water flows left and right through the first drainage channel 534 in the surface light emitting member frame member 53 and further flows downward. When the lower frame member flows left and right through the first drainage channel 534, it overflows and falls from the opening and is discharged from the drainage port 134 of the cover frame member 13 to the outside. In addition, the water that has flowed from the first drainage channel 534 into the second drainage channel 536 in the upper member also flows left and right and downward, and is discharged from the drainage port 134 to the outside as it is.

Thus, in the display device 5 of the second embodiment, similarly to the display device 1 of the first embodiment described above, the wall portion 532 and the simple structure of the first and second drainage channels 534 and 536 are as follows. The adhesion of water to the surface light emitting member 52 and the like can be suppressed.
