## Abstract

An electronic device includes: a backlight holding case 8 accommodating a light guide plate 7; a design frame 3 which includes a flange part 3a protruding inward from a peripheral edge of a frame opening, and a design panel part 3b protruding outward therefrom, and which is attached to an opening of a backlight holding case 8 to sandwich the plate 7 between the flange part 3a and backlight holding case 8; a protective-plate-attached liquid crystal display panel 2 in which a protective plate 2a is mounted on a display surface, and which the outer peripheral part of the protective plate 2a is fixed to the panel part 3b, and the back side is illuminated with light from the light source guided by the plate 7; and a rear side case 4 assembled to the design frame 3 fixed by the panel 2 through the panel part 3b.

## Claims

### Claim 1

An electronic device comprising:
a case of which one surface is open, and which accommodates an illumination light source part that includes a light guide body;
a generally planar liquid crystal display panel in which a protective plate is mounted on a display surface;
a design frame which includes a flange part that protrudes inwardly toward the liquid crystal display panel from a peripheral edge of the design frame, and a design panel part that protrudes outward from the peripheral edge of the design frame in a direction generally perpendicularly from the liquid crystal display panel to constitute an exterior design on a display surface side, the flange part being attached to sides of the case to sandwich the light guide body between the flange part and the case;
the liquid crystal display panel having an outer peripheral part of the protective plate fixed to the design panel part, and thus a back side thereof being illuminated with light from a light source guided by the light guide body; and
a casing body on a rear side which is assembled to the design frame to which the liquid crystal display panel is fixed through the design panel part.
