Abstract

In a liquid-crystal module equipped with a frame, a bezel, and a liquid-crystal panel, the frame includes groove sections. Each of the groove sections has an upper portion formed into an essentially-semicircular shape conforming to an outer peripheral shape of a cylindrical insert nut provided on a side surface of a bezel, and a circular-arc bulging portion provided on at least one side surface of the groove section such that a distance between the bulging portion and an opposing side surface becomes smaller than an outer diameter of the insert nut. Further, the plurality of groove sections are provided at predetermined intervals so as to penetrate from an exterior surface to an interior surface of the frame.

Claims

1. A liquid-crystal module comprising:

a liquid-crystal panel;

a frame of resin supporting an outer peripheral portion of the liquid-crystal panel;

a metal bezel having a recessed section into which the frame of resin is to be inserted;

a cylindrical insert nut which is mounted on a side surface of the bezel so as to project toward an interior surface of the recessed section of the bezel and which has a thread groove in the interior surface thereof;

a first screw hole provided in the side surface of the bezel for inserting the screw when the frame is fitted into and fixed to the recessed section of the bezel;

a second screw hole having a female thread which is provided at a position on the side surface of the frame corresponding to the first screw hole and is for fastening the screw; and

a groove section which is provided so as to have a predetermined depth from a bottom section of an exterior surface of the frame and houses the insert nut projecting toward the interior surface of the bezel, wherein

the groove section is formed in a predetermined number at predetermined intervals so as to penetrate from the exterior surface to the interior surface of the frame; and

each of the plurality of groove sections includes

an upper portion formed into an essentially semicircular shape so as to follow an outer peripheral shape of the cylindrical insert nut and

a circular-arc bulging portion for fixing the insert nut to the upper portion of the groove section, the bulging portion being provided on at least one side surface of the groove section such that a distance between the bulging portion and an opposing side surface becomes smaller than an outer diameter of the insert nut.

2. A liquid-crystal module according to claim 1, further comprising:

a cavity section which renders easy to deflect the side surface having the bulging portion of the groove section formed thereon and which is provided at a position spaced, a predetermined distance, from at least one side surface having the bulging portion of the groove section formed thereon, so as to penetrate from the exterior surface to the interior surface of the frame.

3. A liquid-crystal display device, comprising:

a liquid-crystal panel;

a frame for supporting an outer peripheral portion of the liquid-crystal panel;

a bezel having a recessed section into which the frame is to be fitted;

a nut member which is provided in the bezel so as to project toward an interior surface of the recessed section of the bezel and has a screw thread on an interior circumferential surface thereof; and

a groove section provided in the frame for housing the nut member, wherein

the groove section has a bulging portion which is provided on at least one side surface of the groove section such that a distance between the bulging portion and an opposing side surface becomes smaller than an outer diameter of the nut member.

4. The liquid-crystal display device according to claim 3, wherein

the groove section is formed in a predetermined number at predetermined intervals so as to penetrate from an exterior surface to the interior surface of the frame.

5. The liquid-crystal display device according to claim 3, wherein

the nut member assumes a cylindrical shape;

and the groove section includes an essentially semicircular upper portion formed so as to follow an outer peripheral shape of the cylindrical nut member.

6. The liquid-crystal display device according to claim 3, wherein

the frame further includes a cavity section which is spaced a predetermined distance from at least one side surface of the groove section for rendering the side surface of the groove section easy to deflect.

7. The liquid-crystal display device according to claim 6, wherein

the cavity section is formed so as to penetrate from the exterior surface to the interior surface of the frame.
