[0006]

However, in recent years, as the flat display device has become thinner, the glass substrate 1, the frame 3, the bezel 7, and the like have been significantly thinner.

For this reason, as the thickness is reduced, the connecting and fixing portions of the glass substrate 1, the frame 3, the bezel 7, and the like are miniaturized, and high precision is required, which causes technical difficulties.

Further, as the thickness is reduced, the strengths of the connecting portion and the fixing portion are reduced, and due to the improvement of the assembling accuracy, each member is likely to be damaged, and the workability may be reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to reduce damage to mechanical members and improve workability in the process of assembling a flat panel display.

The present invention has been made in view of the above problems, and has as its object to provide a flat display device which has improved workability and reduced damage to components.

According to the present invention, there is provided a glass substrate having display elements in an XY matrix, an inner shape corresponding to a planar outer shape of the glass substrate, and an end face of the glass substrate positioned from the periphery. A frame in which at least a part of the inner shape expands in the direction of inserting the glass substrate, and at least a part of the inner shape of the frame expands in the direction of inserting the glass substrate. As a result, the glass substrate is easily and reliably positioned inside the frame.

Further, the frame has a back support for supporting the glass substrate from the back and a bezel for fixing the glass substrate to the frame from the front side, so that the glass substrate can be easily fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the flat panel display according to the present invention will be described with reference to the drawings. The parts corresponding to the conventional example shown in FIG.

The flat display device shown in FIG. 1 has a transparent glass substrate 1 having a rectangular shape in a plane, and an XY matrix display element (not shown) is formed on the glass substrate 1.
An end surface 2 substantially perpendicular to the plane direction is formed around the periphery.

The glass substrate 1 is accommodated in a frame 3 having a corresponding shape whose inner shape is slightly larger than the planar outer shape of the glass substrate 1.
A glass edge support 4 is formed perpendicular to a plane direction parallel to the edge of the glass substrate 1 and faces the edge 2 of the glass substrate 1. One end of the glass edge support 4 has a glass substrate 1 An alignment reference surface 4a is formed in parallel with the end surface 2 of the glass substrate 1. On the other end opposite to the alignment reference surface 4a, the width of the lower surface corresponds to the width of the end surface 2 of the glass substrate 1, and the angle θ Inclined surface that expands upwards with
4b is formed. Further, on the back side of the frame 3, a glass back supporting portion 5 for supporting the glass substrate 1 from the back side.
Is formed so as to protrude toward the center, and a back opening 6 which is smaller than the glass substrate 1 and is substantially similar to the glass substrate 1 and which can emit light from the back is formed at the center.

On the front side of the frame 3, a frame-shaped bezel 7 having an L-shaped cross section is provided.
It has a front plate portion 8 covering the front side of the glass substrate 1 and the frame 3, and a display opening 9 slightly smaller than the glass substrate 1 is formed in the center of the front plate portion 8. The peripheral portion 10 which is slightly larger than the periphery of the frame 3 and located around the frame 3 is bent.

When the flat panel display is formed, the glass substrate 1 is inserted from the front side of the frame 3 and one end face 2 of the glass substrate 1 is positioned on the positioning reference plane 4a. Is positioned on the frame 3 and the other end surface 2 is inserted from the side that is expanded to match the inclined surface 4b, and the glass substrate 1 descends according to the inclined surface 4b having a gentle angle θ. To the correct position and can be easily fitted to the correct position.

Further, the back of the glass substrate 1 is placed on the glass back support 5 of the frame 3, and the bezel 7 is positioned on the front side of the frame 3 and the glass substrate 1. 3 from the front side, bezel 7
Of the frame 3 around the frame 3
Further, the glass substrate 1 is sandwiched and fixed by the bezel 7 from above and below.

Even if the glass substrate 1 is displaced from the correct position of the frame 3, the glass substrate 1 is guided to a normal position by being pressed from above by the bezel 7.

Further, as shown in FIG.
Frame 3 in order to more securely fix
From the glass back support 5 to the glass end support 4
An adhesive tape 11 such as a double-sided tape may be attached over 4b, and the frame 3 and the glass substrate 1 may be adhered. Also in this case, since the inclined surface 4b has a gentle angle, the glass substrate 1 can be easily positioned at an appropriate position on the frame 3, so that workability can be improved.

Further, in the above embodiment, the frame 3 has the pair of opposing surfaces having the positioning reference surface 4a and the inclined surface 4b, but the other pair of opposing surfaces has the same shape. Is also good.

According to the present invention, at least a part of the inner shape of the frame is formed so as to expand in the direction of inserting the glass substrate, so that the glass substrate can be easily and reliably positioned inside the frame. The member can be located at an appropriate position without being stressed and damaged.

Further, since the glass substrate is supported from the back by the back support portion of the frame, and the glass substrate is fixed to the frame with the bezel from the front side, the glass substrate can be more appropriately fixed more easily.
