Abstract

A display device includes a display panel that includes a first hole and a device housing that is configured such that the display panel is fastened and fixed to the device housing by a screw passed through the first hole and screwed into the screw hole. The display panel includes a display-side positioning part which is configured to fit to a portion of the device housing to perform positioning of the display panel with respect to the device housing and which includes the first hole, and the device housing includes a housing-side positioning part which is configured to fit to the display-side positioning part to perform the positioning and which includes a second hole formed so as to communicate with the first hole when the housing-side positioning part is fitted to the display-side positioning part.

First claim

What is claimed is:

1. A display device comprising:
a display panel including a display screen, the display panel being provided with a first hole for screw fixation, the first hole being formed on an outer periphery side of the display screen; and
a device housing having a bottomed tube-shape and including an opening configured to be covered with the display panel, the device housing including a second hole, the second hole being formed at a position that communicates with the first hole, the first hole being one of a through hole and a screw hole, the second hole being the other of the through hole and the screw hole, the device housing being configured such that the display panel is fastened and fixed to the device housing by a screw passed through the through hole and screwed into the screw hole,
wherein
the display panel includes a display-side positioning part which is configured to fit to a portion of the device housing to perform positioning of the display panel with respect to the device housing and on which the first hole is formed, and
the device housing includes a housing-side positioning part which is configured to fit to the display-side positioning part to perform the positioning and on which the second hole is formed so as to communicate with the first hole when the housing-side positioning part is fitted to the display-side positioning part
the display-side positioning part is a portion provided with a recessed part opening toward the device housing, the first hole being formed on a bottom of the recessed part, and
the housing-side positioning part is a protruded part configured to fit to the recessed part, the second hole being formed on the housing-side positioning part so as to open on an abutting face that abuts on the bottom of the recessed part when the protruded part is fitted to the recessed part,
the display-side positioning part includes ribs disposed on a back face of the display panel that faces the device housing, and
a space surrounded by the ribs is the recessed part.

2. The display device according to claim 1 , wherein
the first hole is the through hole formed so as to penetrate through the bottom of the recessed part, and
the protruded part is formed thick in an insertion direction of the screw, the screw hole being bored, as the second hole, in the insertion direction from the abutting face.

3. The display device according to claim 2 , wherein the display panel is provided with an outer face recess that is recessed to accommodate a screw head of the screw passed through the through hole, the outer face recess being formed on an outer face of the display panel on a side opposite to the device housing at a portion corresponding to the display-side positioning part.

4. The display device according to claim 1 , wherein the protruded part as the housing-side positioning part is formed to protrude from an outer face of a peripheral wall of the device housing,
the display panel is a member extending wider than the opening of the device housing, the ribs are formed so as to surround the housing-side positioning part on three sides excluding the peripheral wall when the display panel covers the opening.

5. The display device according to claim 4 , wherein
a pair of the protruded parts as the housing-side positioning parts protrude from respective outer faces of a pair of wall portions, that faces each other, of the peripheral wall of the device housing, and
a pair of the recessed parts of the display-side positioning parts are formed on the back face of the display panel such that the pair of the protruded parts fits to the pair of the recessed parts, respectively.

6. The display device according to claim 1 , wherein
a depth of the recessed part of the display-side positioning part is less than a length of the housing-side positioning part from the abutting face.

7. The display device according to claim 1 , wherein
the ribs surround the housing-side positioning part on three sides excluding the peripheral wall when the display panel covers the opening.
