  In order to solve the above problems, a first electro-optical device according to the present invention includes an electro-optical panel, a light guide plate arranged to face one panel surface of the electro-optical panel, the electro-optical panel, A housing case for housing the light guide plate, the housing case being located on the opposite side of the light guide plate from the one panel surface, and at least part of the periphery from the bottom portion. A second side wall portion that is bent and is folded back along the first side wall portion from the first side wall portion to the side where the light guide plate is accommodated. A metal member having a side wall portion and an extending portion that is bent from the second side wall portion and extends partially along the bottom portion;

  A first electro-optical device according to the present invention includes an electro-optical panel, a light guide plate constituting a backlight, and a housing case. The electro-optical panel is, for example, a liquid crystal panel, and modulates light in an electro-optical material such as a liquid crystal according to a voltage level applied in units of each pixel in the display region. The electro-optical panel forms a module together with the backlight, and is housed in the housing case. The backlight includes a light guide plate that guides light from a light source such as an LED to an electro-optical panel. The light guide plate is disposed so as to face one panel surface with respect to the electro-optical panel. In such an electro-optical panel, light from a light source is incident on one panel surface via a light guide plate, modulated by an electro-optical material such as liquid crystal, and emitted as display light, for example. .

  The storage case includes a metal member. For example, the storage case includes a metal member and a resin member provided integrally with the metal member. In this case, the housing case is manufactured, for example, by so-called insert molding in which a metal member produced in advance by press working technique or the like is fitted into a mold, and a molten resin material is poured into the mold and solidified. In the housing case, the electro-optical panel and the backlight are housed in an opening defined by the metal member and the resin member.

  The metal member has a bottom portion, first and second side wall portions that at least partially define the opening together with the bottom portion, and an extended portion that is further bent and extended from the second side wall portion. In a state where the electro-optical panel and the backlight are housed in the housing case, the bottom portion of the metal member is located on the side opposite to the one panel surface with respect to the light guide plate. The first and second side wall portions are located on the side of the light guide plate. The first side wall portion is bent from the bottom portion along at least a part of the peripheral edge thereof. The second side wall portion is provided by being folded back along the first side wall portion by hemming, for example, on the side where the light guide plate is further accommodated from the first side wall portion. The extension part is bent from the second side wall part and extends partially along the bottom part.

  When the housing case includes a resin member in addition to the metal member, the resin member is formed to have, for example, a third side wall portion that at least partially surrounds the side surface of the light guide plate from the outer peripheral side. The The resin member is formed of, for example, a resin material having a light reflection performance capable of reflecting light, and the light emitted from the side surface of the light guide plate is reflected at least partially on the third side wall portion, thereby improving efficiency. The light from the light source can be made incident on the electro-optical panel through the light guide plate.

  By supporting the electro-optical panel and the backlight with a metal member in the housing case, it is possible to ensure the strength of the electro-optical device against an impact applied by, for example, dropping.

  In the present invention, in particular, the side wall portion of the housing case is at least partially formed by overlapping the first and second side wall portions of the metal member by, for example, hemming, and further continuously on the bottom portion with the second side wall portion. And has an extending portion that partially overlaps. Therefore, in the housing case, the strength can be improved at least partially from the side wall portion to the corner portion where the side wall portion is bent from the bottom portion formed by the bottom portion of the metal member. Therefore, it is possible to reliably improve the strength of the entire electro-optical device.

Such fitting makes it possible to more reliably prevent the resin member from separating from the metal member and damaging the housing case.

  In the aspect in which the first opening portion is formed in the extending portion, the second opening portion that overlaps the first opening portion as viewed in a plan view from the side facing the light guide plate is formed on the bottom portion. The resin member may be formed so as to embed the second aperture portion in addition to the first aperture portion.

The first side wall 66a is bent from the bottom 66e along at least a part of the peripheral edge thereof, and the second side wall 66b is further hemmed, for example, on the side where the organic EL panel 200 is accommodated from the first side wall 66a. Thus, it is folded back along the first side wall portion 66a. The extending part 66c is bent from the second side wall part 66b and extends partially along the bottom part 66e.

  The resin member 67 is provided integrally with the metal member 66 inside the metal member 66 (that is, the side of the metal member 66 on which the organic EL panel 200 is disposed). The resin member 67 is formed so as to cover the second side wall portion 66b, the bottom portion 66e, and the extending portion 66c from the side facing the organic EL panel 200.

  According to the housing case 65 as described above, the organic EL panel 200 is supported by the metal member 66 in addition to the resin member 67, so that the strength of the organic EL device against an impact caused by dropping or the like can be ensured. In particular, the side wall portion of the housing case 65 is at least partially formed by overlapping the first side wall portion 66a and the second side wall portion 66b in the metal member 66 by, for example, hemming, and is continuous with the second side wall portion 66b. In particular, it has an extending portion 66c extending partially overlapping the bottom 66e. Therefore, in the housing case 65, it is possible to improve the strength at least partially from the side wall portion to the corner portion where the side wall portion is bent from the bottom portion formed by the bottom portion 66e of the metal member 66.

  In addition, since the first side wall portion 66a and the second side wall portion 66b overlap each other, the organic EL panel 200 is at least partially supported from the side surface side in the housing case 65 by the first side wall portion 66a and the second side wall portion 66b. It becomes possible, and the intensity | strength of the said organic EL apparatus can be improved more reliably.

  As described above, according to the organic EL device according to the present embodiment, the housing case 65 includes the metal member 66 having the bottom 66e, the first side wall 66a, the second side wall 66b, and the extending part 66c. Therefore, the strength of the organic EL device can be reliably improved.

  Here, in FIG. 7, a recess 66 ch is formed on the side of the extending portion 66 c facing the organic EL panel 200, and the resin member 67 has a recess 66 ch from the side of the extending portion 66 c facing the organic EL panel 200. It is formed so as to be embedded and covered. Accordingly, the resin member 67 can be formed by fitting a portion embedded in the recess 66ch into the recess 66ch of the extending portion 66c. By such fitting, it is possible to more reliably prevent the housing case 65 from being damaged due to the resin member 67 being separated from the metal member 66 due to an impact such as dropping. As a result, the strength of the organic EL device can be improved more reliably.
