Abstract

The present invention addresses the problem of providing a display device that excels in waterproofness against moisture from a display side. A display device is provided with: a display for displaying an image on a display surface; a cover plate located on the display surface side of the display, the cover plate having a light-transmitting section for making the display surface visible; an elastic member provided so as to cover the side circumferential section of the cover plate; and an accommodation body having an open section that is open toward the cover plate side and a protruding section encircling the open section and protruding to the outer circumferential side of the open section. The display is bonded to the cover plate with a photocurable adhesive. The cover plate is secured via the elastic member to the protruding section by a caulked metal frame body.

First claim

1 . A display device comprising:
a display for displaying an image on a display surface; a cover plate located on the display surface side of the display, the cover plate having a light-transmitting portion for making the display surface visible; an elastic member provided so as to cover the side circumferential portion of the cover plate; and an accommodation body which is located further toward the display side than the cover plate and accommodates the display, the accommodation body having an opening that opens toward the cover plate side and a protruding portion surrounding the opening and protruding to the outer circumferential side of the opening, wherein the display is bonded to the cover plate by a photocurable adhesive, and wherein the cover plate is fixed via the elastic member to the protruding portion by a caulked metal frame body.

2 . The display apparatus according to claim 1 , further comprising
a case body which is located further toward the display side than the cover plate and is accommodated in the accommodation body, wherein a circuit substrate connected electrically with the display is fixed to the case body on the side opposite to side of the cover plate, and the case body has a recessed portion which is recessed toward the circuit substrate side from the cover plate side and accommodates the display.

3 . The display apparatus according to claim 2 , wherein
a step portion surrounding the opening is formed in the accommodation body on the opening side of the protruding portion, and a flange portion which fits in the step portion is formed in the case body.

4 . The display apparatus according to claim 3 , wherein
a depth of the step portion and a thickness of the flange portion are substantially equal and, when the flange portion fits in the step portion, the protruding portion and the flange portion are located on substantially the same plane on the cover plate side and constitute a mounting surface on which the elastic member is placed.

5 . The display device according to claim 1 , wherein
the accommodation body has a wall portion standing along the normal direction of the display surface, the protruding portion is located at an end portion of the wall portion on the cover plate side and protrudes on an outer circumferential side of the opening rather than the wall portion, an inclined portion connected with the wall portion, not perpendicularly crossing the normal direction but inclined is provided in the protruding portion on the side opposite to the side of the cover plate, and the frame body is bent along the inclined portion.

6 . The display apparatus according to claim 5 , wherein
when seen from the display surface side, the inclined portion is provided to surround the opening except for a part, and in that part, a horizontal portion connecting with the wall portion and crossing the normal direction substantially perpendicularly is provided in the protruding portion on the side opposite to the side of the cover plate.

7 . The display device according to claim 3 , further comprising
a substrate for a temperature sensor on which a temperature sensor is mounted, wherein an accommodation space for accommodating the substrate for a temperature sensor is formed between the recessed portion and the flange portion of the case body.
