In general, display devices such as TVs and monitors are being developed in the form of a CRT, a liquid crystal display (LCD), and a plasma display panel (PDP).

In the case of a CRT type display device, there is a limit to the production of a large screen, so the use thereof may be significantly reduced, and an LCD display device is usually manufactured in a small size, and a PDP display device is manufactured in a large size. It is also used as a display for wall-mounted TVs.

The PDP is a self-luminous display device that displays an image using plasma discharge. The PDP is thin and large in size and has high quality, and has recently been applied to wall-mounted or high-definition televisions.

A front mask 11 is formed at the forefront, a filter glass 12 is in close contact with the rear side of the front mask 11, and the filter glass 12 Frame 13 is coupled to the front mask 11 to fix the front mask 11 to the front mask 11.

A PD module 14 is mounted at the rear of the filter glass 12, and a back cover 15 for covering the component is coupled with the front mask 11.

The filter glass 12 serves to protect the color of the screen generated by the PD module 14, and block electromagnetic waves.

Meanwhile, a sponge 16 is usually mounted between the frame 13 and the PD module 14 to prevent foreign substances, such as dust, from entering between the PD module 14 and the filter glass 12.

In addition, the front mask 11 generally uses a plastic material, the filter glass 12 uses a holding material, and the frame 13 uses a metal material.

Accordingly, the front surface of the filter glass is in surface contact with the rear surface of the front mask, and the rear surface is in surface contact with the frame, thereby being stably fixed.

However, when vibration occurs due to an impact generated during the movement of the display device, the shock is transmitted to the filter glass, thereby causing damage.

In addition, even though the frame and the filter glass are in surface contact, the surface of the filter glass is not smooth, and thus the point is in contact with the frame.

In particular, since there is no separate part for seating the filter glass at a specific position of the front mask, the position of the filter glass is slightly different for each front mask, so that the contact area with the frame when the filter glass is not seated in the correct position. Although there is a difference in the ultimate support capacity for each side of the filter glass is a problem that is not a stable installation.

Accordingly, the present invention has been made to solve the above problems, the present invention is to prevent the shock is transmitted to the filter glass through the impact of the display device while ensuring that the filter glass in a stable position on the front mask. Instead, it aims to suppress the generation of electromagnetic waves by making the filter glass and the frame have sufficient surface contact.

The present invention for achieving the above object is in the filter glass installation structure of the display device that the front face is in contact with the front mask and the back is fixed to the frame,

The front mask has a filter glass installation structure of a display device, characterized in that the curved surface bent backward to contact the filter glass and a portion of the surface and a plurality of ribs for contacting the end surface of the filter glass protrudes up, down, left and right. to provide.

The above configuration allows the filter glass to be seated in place by the ribs, and reduces the frictional force by only partially contacting the filter glass by the curved surface of the front mask.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

In addition, this embodiment is presented by way of example only, not limiting the scope of the present invention, the same parts as the conventional configuration uses the same reference numerals or names.

2 is a view showing the back of the front mask according to the present invention, Figure 3 is a cross-sectional view showing a state in which the filter glass according to the present invention is installed.

As shown, an opening hole 21 is formed in the center of the front mask 20 so that an image can be seen.

The filter glass 31 is seated on the rear surface of the front mask 20 to cover the opening hole 21.

In this case, an end surface of the front mask 20 in which the opening hole 21 is formed has a curved surface 22 which is bent and protrudes to the rear, thereby the front mask 20 and the filter glass 31. The contact area of is minimized.

In addition, ribs 23 are formed to protrude from the rear surface of the front mask 20, and the ribs 23 are formed in the up, down, left and right directions of the front mask 20 with respect to the opening hole 21, and a filter.
