  By the way, display devices such as televisions are becoming larger and more demanding to be thin. However, in the edge light type display device configured as in Patent Document 1, color unevenness and luminance unevenness are likely to occur with the increase in size, and it is difficult to adapt to the increase in size. Further, in the direct light type display device configured as in Patent Document 2, it is difficult to reduce the thickness because a plurality of light sources and one diffusion plate need to be relatively separated from each other. is there.

  FIG. 13 is a longitudinal side view showing the configuration of the previously developed display device. The applicant of the present invention first developed a display device including a diffusion plate 101 and a plurality of light guide plates 100 as shown in FIG. 13 in order to further reduce the thickness even when the size is increased. This display device has a substantially rectangular shape, and is opposed to a plurality of light guide plates 100 having a light exit surface 100a on one side of one surface and a non-light output surface 100b on the other side, and the light output surfaces 100a of each of the light guide plates 100. A diffusion plate 101 that diffuses light emitted from the surface 100a, a substrate 103 on which a light emitting diode 102 facing the other edge of each of the light guide plates 100 is mounted, and an accommodation recess 104a that accommodates the substrate 103 and the light guide plate 100 The non-light-emitting surface 100b and the other surface on the light-emitting surface 100a side of the adjacent light guide plates 100 are stacked in a plurality of rows.

  By the way, in the previously developed display device, the non-light-emitting surface 100b of the light guide plate 100 arranged at one end of the column does not emit light, so that a diffusion plate is not provided at a position facing the non-light-emitting surface 100b. 101 may be omitted. Therefore, the diffusion plate 101 does not have a portion facing the non-light-emitting surface 100b and is formed to have a size slightly larger than the total area of the light-emitting surfaces 100a of the light guide plates 100. It is preferable to reduce the size of the diffusion plate 101 and reduce the cost by eliminating the extra portion.

  However, when configured in this way, the three edges of the diffusion plate 101 having a substantially square shape can be supported by the three edges of the support 104, but one edge facing one end of the row of the light guide plates 100. The portion cannot be supported by the edge of the support 104, and is suspended from the support 104. Therefore, the position of the display unit 105 disposed opposite to the diffusion plate 101 with respect to the support 104 is not fixed, and an improvement measure is provided. Was requested.

It is preferable that the receiver is arranged at a position facing the non-light-emitting surface of the light guide plate at one end of the row.
In the present invention, since the receiver is disposed at a position facing the non-light-emitting surface that does not overlap with the adjacent light guide plate, the thickness of the receiver is relatively thick within the thickness of the overlapping portion of the light guide plates. It is possible to increase the rigidity of the receiver.

Further, the display device according to the present invention includes a substrate on which a light source facing the other edge of each of the light guide plates is mounted and attached to the support, and each of the light guide plates is held on the substrate. A configuration is preferable.
