Are light emitters for supplying illumination light to the front side (panel 21 side) and illuminating the design portion 21a. The light source 22 is supplied with lighting power through the circuit board 13.

  And when the situation which should perform a warning and alerting | reporting in the predetermined design part 21a according to the electric signal from the various sensors occurs, the predetermined design part 21a is adapted to correspond to the predetermined design part 21a. By turning on the predetermined light source 22 located immediately below, the illumination light emitted from the predetermined light source 22 is guided to the panel 21 side through the illumination chamber. The illumination light guided to the panel 21 side is transmitted through a predetermined light transmitting portion 21b formed around the predetermined design portion 21a, whereby the predetermined design portion 21a is backlit, thereby Information to be notified to the user who uses the vehicle is displayed in a light-emitting manner.

  The frame body 23 is made of, for example, white light-shielding synthetic resin, and is disposed between the panel 21 and the circuit board 13 and guides illumination light from each light source 22 to the panel 21 side (each design portion 21a side). A plurality of illumination chambers 23a are provided.

  In this case, the illumination chamber 23a is surrounded by the first side wall part 31, the second side wall part 32, the third side wall part 33, and the fourth side wall part 34 as shown in FIGS. It consists of a hollow area. And the support part 35 for supporting the panel 21 by each side wall part 31-34 is comprised.

  Here, the first side wall portion 31 of the support portion 35 is formed to have a stepped shape, and includes an upper side wall portion H1 located on the panel 21 side, a lower side wall portion H2 located on the circuit board 13 side, It has the connection part H3 which connects the upper side wall part H1 and the lower side wall part H2.

Since it is configured to overlap the upper side of the non-display area 11c located on the light emitting display member 20 side in the element 11, the overall vertical dimension in the vertical direction of the display device (the arrow Y direction in FIG. 1) in FIG. In FIG. 1, S is a dimension obtained by adding the upper vertical dimension T4 of the non-display area 11b positioned above the display element 11a, the vertical dimension T3 of the display area 11a, and the vertical dimension T2 of the panel 21.

  Therefore, according to the prior art, the lower vertical dimension T5 in the non-display area (that is, the vertical dimension of the non-display area 11c located on the light emitting display member 20 side in the present embodiment) is the overall vertical dimension S (of the display element 10). In contrast to the vertical dimension T1), according to the present invention, the first wall portion H1 of the first side wall portion 31 is disposed above the non-display area 11c located on the light emitting display member 20 side. Furthermore, since the required part of the panel 21 is placed on the first wall H1, the vertical dimension of the non-display area 11c located on the light emitting display member 20 side is the overall vertical dimension S (the vertical dimension of the display element 10). The configuration is not included in the dimension T1). That is, when the display device is viewed from the front as shown in FIG. 1, the panel 21 is arranged on the display area 11 a side by the vertical dimension of the non-display area 11 c as compared with the conventional case. In the middle, the value of the overall vertical dimension S in the direction of the arrow Y can be set as a smaller dimension value than the conventional one, thereby providing a display device that can be miniaturized.

Since it is configured to be visible from the user side and other areas are not visible from the user side, it is possible to provide a display device with high merchantability without deteriorating the appearance quality.

  Moreover, although this embodiment demonstrated the example which formed the several design part 21a adjacent to the substantially strip | belt-shaped panel (indicator panel) 21, for example, as shown in FIG. A flat lens member (indicator lens) 40 having a portion D formed thereon and a textured surface on the back surface is adopted, and the illumination chamber 23a (by the support portion 35) is provided for each illumination chamber 23a partitioned. A configuration may be adopted in which each is embedded in an upper end side opening in the enclosed hollow region and supported by the support portion 35. In this case, the design portion D may be provided not on the surface of the lens member 40 but on the back surface of the lens member 40.

  Further, in the present embodiment, an example in which the first wall portion H1 of the first side wall portion 31 that is a part of the support portion 35 overlaps with the non-display area 11c located on the light emitting display portion 20 side in substantially the entire region has been described. However, for example, the first wall H1 of the first side wall 31 may be configured to partially overlap the non-display area 11c. In short, at least the first wall H1 in the first side wall 31 is at least It suffices if a part thereof overlaps the non-display area 11c.

  In the present embodiment, the example in which the first side wall portion 31 includes the first and second wall portions H1 and H2 and the connecting portion H3 that connects both the wall portions H1 and H2 has been described. For example, FIG. As shown, the first wall H1 and the connecting part H3 are eliminated, and the second wall H2 extends straight toward the panel 21 so that the second wall H2 supports the back surface of the panel 21 ( In other words, the second wall portion H2 is formed as a standing wall portion that hangs down from the back surface of the panel 21 toward the circuit board 13 side), and the display member 10 side from the non-display area 11c and the second wall portion H2. When the display device is viewed from the front, the outer edge portion 50 of the panel 21 overlaps with the non-display area 11c when the display device is viewed from the front side. It is good also as such a structure.

  Further, as described above, the outer edge portion 50 of the panel 21 does not overlap with the non-display area 11c. For example, the outer edge portion 50 of the panel 21 is eliminated as shown in FIG. A cover portion 60 is formed integrally with the second wall portion H2 so as to cover the non-display area 11c from the portion H2, and this cover portion 60 (that is, a part of the frame body 23) overlaps the non-display area 11c. It is good also as such a structure. The outer edge part 50 and the cover part 60 may be configured so that at least a part thereof overlaps the non-display area 11c. Moreover, it cannot be overemphasized that it replaces with the panel 21 and the lens member 40 may be employ | adopted in the structure of FIG.5 and FIG.6 mentioned above.
