FIG. 1 is an exploded view of an optical filter mounting structure according to the present invention. FIGS. 2A and 2B are a front view, an enlarged cross-sectional view of a part c1-c1 of FIG. 2B, and an enlarged cross-sectional view of a part c2-c2 of FIG. is there. An optical filter 2 is mounted on the front surface of a front frame 1 of a display device using a PDP (not shown) as a display device. A plurality of hook-shaped projections 1a serving as locking tools are provided on the upper portion of the front surface of the front frame 1 in a protruding manner. Insert the projection 1a into the hole 2a opened in the upper part of the periphery of the optical filter 2,
The optical filter 2 is attached to the front frame 1. A plurality of substantially columnar projections 1b are provided on both sides of the front surface of the front frame 1. The projection 1b is inserted into a substantially oval or elliptical hole 2b opened on both sides around the optical filter 2 to hold the optical filter 2 so as not to shift in the left-right direction.

A decorative frame 3 for covering the optical filter 2 on the front frame 1 is provided on the front surface of a mounting portion such as a projection 1a or 1b for mounting the optical filter 2 on the front frame 1. A plurality of projections 3c having claws are provided on the back surface of the decorative frame 3, and the projections 3c are inserted into holes 1c opened in the front surface of the front frame 1 and locked.

FIG. 3 is a side view (cross section) of a main part of another embodiment of the optical filter mounting structure according to the present invention. As described above, the optical filter 32 is mounted on the front surface of the front frame 31 of the display device using the PDP. A plurality of protrusions 31a are provided on the front surface of the front frame 31. The projection 31a is connected to the optical filter 32.
Into the plurality of holes 32a opened in the periphery of the
The optical filter 32 is attached to the front frame 31 by being locked by a protrusion 31b provided in the lateral direction at the tip of 1a. On the front surface of the mounting portion of the optical filter 32, the decorative frame 3 covering them is mounted in the same manner as described above.

[0013]

The present invention is embodied in the form described above, and has the following effects.

A plurality of holes are opened in the peripheral portion of the optical filter, and a projection-like locking member protruding from the front frame is provided at a portion corresponding to the front frame of the display device. By mounting the optical filter on the front frame by inserting it into the hole opened in the filter, the optical filter can be attached and detached from the front of the display device. Maintenance and service are no longer required.

On the front surface of the locking member of the optical filter, a projection-shaped locking member projecting from the rear surface is inserted into a hole opened in a corresponding portion of the front frame and attached to cover the mounting portion of the optical filter. By providing the decorative frame, the mounting position of the locking tool can be freely set at almost any place without regard to the appearance.

The locking member of the optical filter is a hook-shaped projection projecting upward from the front of the front frame and having a tip bent upward.
By inserting a hole opened in the upper part of the periphery of the optical filter into the hook-shaped protrusion and catching it, a locking tool that can be easily attached and detached can be used.

A columnar projection is projected from both sides of the front surface of the front frame, and the columnar projection is inserted and held in a substantially oval or elliptical hole on both sides around the optical filter. Thus, the optical filter can be easily held so as not to be displaced in the lateral direction.

The locking member of the optical filter is a projection having a laterally convex portion at the tip protruding from the front surface of the front frame, and the projection is inserted into a hole opened in the optical filter to form the convex portion. By locking the optical filter, another locking means that can be easily attached and detached is obtained.
