The bezel 205 does not serve as an exterior housing, and an exterior housing may be separately provided on the outside of the bezel 205.

The bezel 205 is formed using a metallic material such as aluminum. As a result, the bezel 205 has sufficient strength as an exterior housing. Further, the bezel 205 has a higher rigidity than the resin panel support member 204. As a result, when the bezel 205 is attached to the panel support member 204, the deformation of the bezel 205 can be suppressed. The bezel 205 may be formed by using a metal material other than aluminum (for example, iron) or various resin materials.

As shown in FIG. 2, FIG. 4 or FIG. 5, the bezel 205 includes a front surface portion 251 and a bezel side surface portion 252, and has a substantially L-shaped cross-sectional shape. Further, the bezel 205 includes an extending portion 401 shown in FIG. 4 and a protruding portion 502 shown in FIG.

The front surface portion 251 is located in front of the display surface 111, abuts on the display panel 201 via the spacer 207, and supports the display panel 201 from the front side.

The display surface 111 of the display panel 201 is exposed from the opening of the frame-shaped front portion 251.

The bezel side surface portion 252 is formed from the end portion of the display panel 111 from the outside of the front surface portion 251 (opposite to the center of the display surface 111 in the plan view in the normal direction of the display surface 111) in the front-rear direction. It bends toward the side, that is, backward, and extends. The bezel side surface portion 252 is located outside the display panel 201 and the panel support member 204, and surrounds the panel support member 204.

The bezel side surface portion 252 is located outside the support side surface portion 242 with respect to the center of the display device 110, and extends along the support side surface portion 242. The surface of the support side surface portion 242 (inside) of the bezel side surface portion 252 and the surface of the bezel side surface portion 252 side (outside) of the support side surface portion 242 are in contact with each other or slightly separated from each other.

As shown in FIG. 4, the extending portion 402 is provided at a position corresponding to the bezel positioning groove 401 provided in the panel support member 204, and extends rearward from the front portion 251. That is, the extending portion 402 extends toward the panel support member 204. The extension portion 402 is inserted into the bezel positioning groove 401, and the bezel 205 is positioned with respect to the panel support member 204.

As shown in FIG. 5, the protrusion 502 is from the inner surface (the surface on the display panel 201 side) of the bezel side surface portion 252 toward the inside (the center side of the display device 110 in a plan view in the front-rear direction), that is, the support side surface. It projects toward the portion 242. The protrusion 502 is provided at a position facing the engaging portion 501 of the support side surface portion 242, and engages with the engaging portion 501.

The bezel 205 is attached from the front of the display panel 201 and is engaged and fixed to the panel support member 204. That is, the bezel 205 is slid from the front to the rear along the panel support side surface portion 242 until the protrusion 502 reaches the engaging portion 501. By engaging the protrusion 502 with the engaging portion 501, the bezel 205 is fixed to the support member 204, and the display panel 201 is sandwiched by the support member 204 and the bezel 205 from the front-rear direction. In the display device 110, as compared with the case where the support member 204 is fixed to the bezel 205 with screws, it is not necessary to perform the screw fastening work, and the efficiency of the assembly work can be improved. Moreover, since screws are not used, the cost can be reduced.

Further, since the engaging portion 501 is provided on the support side surface portion 242 and the protruding portion 501 is provided on the inner surface of the bezel side surface portion 252, the bezel 205 is slid rearward with respect to the support member 204 to engage and fix the support member. The display panel 201 can be sandwiched between the 204 and the bezel 205. That is, in the display device 110, the support member 204 and the bezel 205 can be fixed at the same time, and the display panel 201 can be fixed at the same time, so that the efficiency of the assembly work can be improved.

Further, when the bezel 205 is attached, the support side surface portion 242 is pressed inward from the bezel 205 and elastically deformed. In the present embodiment, the bezel 205 made of a metal material has a higher rigidity than the panel support member 204 made of a resin material, so that the panel support member 204 can be easily elastically deformed and the mounting work is easy. Is.

Since the support side surface portion 242 is formed with a through hole 503, the overlapping portion 702 can be easily elastically deformed when pressed from the protrusion 502, and the attachment work can be made easier. Further, since the thin-walled portion 701 is provided so as to sandwich the through hole 503, the overlapping portion 702 can be more easily elastically deformed.

In the example shown in FIG. 5, the protrusion 502 has a substantially trapezoidal cross-sectional shape, and the rear surface 521 of the protrusion 502 is inclined toward the front. On the other hand, a front inclined surface 504 that inclines toward the rear is formed at least at the end of the front end of the support side surface portion 242 that is located on the front side of the engaging portion 501. By sliding the rear surface 521 against the front inclined surface 504 when the bezel 205 is attached, the support side surface portion 242 can be easily elastically deformed, and the misalignment of the bezel 205 in the left-right direction and the vertical direction can be suppressed.

Further, in the example shown in FIG. 5, at least a part of the rear end portion of the support side surface portion 242, specifically, the end portion located on the rear side of the engaging portion 501 is inclined forward. A rear inclined surface 505 is formed. As a result, a gap into which an instrument or the like can be inserted can be formed between the rear inclined surface 505 and the inner surface of the bezel side surface portion 252, and the bezel 205 can be easily removed.
