Abstract

PURPOSE: To improve the yield strength to the deflection (bending) of a glass surface of external force and load with an LCD structure formed of the glass used to a portable terminal device, etc., as its base. CONSTITUTION: Notches 8 by a blade are put on a raw glass plate 7 at the time of cutting the upper glass 1 and lower glass 2 to be formed as the base of the LCD6 from the raw glass plate. The structure is arranged with the upper glass 1 and lower glass 2 on which the fine flaws (ruggedness) 9 by the blade remain at the end faces by directing both of the blade incoming surfaces 3 thereof toward an LCD display surface 4 side. As a result, the blade incoming surfaces 3 are the compression surface side to the static concentrated load from the LCD display surface 4 side. The structure capable of withstanding the higher load is obtd.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a static pressure resistant structure for LCD (liquid crystal display), and more particularly to a static pressure resistant structure for LCD based on glass.

[0002]

2. Description of the Related Art As shown in FIG.
Is mounted on the front surface side of the terminal device 11, and the LCD 1 bends by an external force applied to the terminal device 11.
2 is likely to occur.

Generally, the LCD 10 is composed of an upper glass 1, a lower glass 2 and a liquid crystal material 5 enclosed between them as shown in FIG. 4, and as shown in FIG. When the large glass base plate 7 serving as a base is cut during the production of the lower glass 1 and the lower glass 2, the surface on which the notch 8 by the blade is formed (hereinafter, referred to as the "inlet surface 3") is the surface opposite the LCD display surface 4. It has a structure for.

When the glass original plate 7 is cut in manufacturing the upper glass 1 and the lower glass 2, fine scratches (irregularities) 9 remain on the end face on the side of the blade insertion surface 3 as shown in FIG. 2 (b). .

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
Under severe working environment, the CD 10 receives a static concentrated load from the LCD display surface 4 side, and when the upper glass 1 and the lower glass 2 are bent 12, the glass breaks with a relatively low load. There is a problem that the above-mentioned problem frequently occurs, and it is easy to break when a load is applied to the outer peripheral portions of the upper glass 1 and the lower glass 2, in particular.

This is because the fine scratches (irregularities) 9 due to the blades remain on the end face on the blade insertion side when the upper glass 1 and the lower glass 2 are cut from the original glass plate 7 during the manufacture of the LCD. Bending that is inferred and that is applied to the glass surface (deflection)
It is considered that the fact that the blade insertion surface 3 is on the opposite surface side of the LCD display surface 4, that is, the tension surface side with respect to the load is the cause of being difficult to withstand the load.

In view of the above-mentioned conventional drawbacks, an object of the present invention is to
An object of the present invention is to provide a structure for strengthening the static pressure resistance of an LCD, which is resistant to glass breakage against impact or external force.

[0008]

An LCD static pressure strengthening structure according to the present invention is an arrangement structure of a glass serving as a base of an LCD, and an edge surface of the glass has a structure for cutting the glass from a glass original plate. The blade has a bladed surface with a notch formed by a blade, and the bladed surface is arranged so as to face the compression surface side of the flexure against the bending of the glass itself caused by a static concentrated load.

[0009]

[Function] When the upper glass and the lower glass, which are the bases of the LCD, are bent (bent) due to a static concentrated load, they are compressed as compared with the state in which the blade surface faces the tensile surface of the bending. By arranging so that it faces the surface side, it is possible to withstand a high load.

[0010]

Next, the present invention will be described with reference to the drawings.

FIG. 1 shows an LCD structure of one embodiment of the present invention, (a) is a sectional view taken along line AA of (b) of FIG.
FIG. 2B is a perspective view, and FIG. 2 is a perspective view showing a state of a blade edge and fine scratches (concavities and convexities) when the glass used in this example is cut from the original plate.

The LCD 6 of this embodiment is mounted on the front surface side of the terminal device 11 as shown in FIG. 3, and includes the upper glass 1, the lower glass 2 and the liquid crystal material 5 enclosed between the two glasses.
Composed of and. The upper glass 1 and the lower glass 2 are shown in FIG.
As shown in FIG. 2, it is manufactured by cutting it from a large glass original plate 7 serving as a base. At that time, a fine scratch as shown in FIG. (Unevenness) 9 remains.

In the construction of the LCD 6, as shown in FIG. 1, both the blade insertion surface 3 of the upper glass 1 and the blade insertion surface 3 of the lower glass 2 are arranged toward the LCD display surface 4 side.

In the present embodiment thus arranged and arranged, it is assumed that the deflection 12 shown in FIG. 3 is generated in the upper glass 1 and the lower glass 2 under the static concentrated load from the LCD display surface 4 side. Also, since the glass surface has the blade edge surface 3 facing the compression surface side against bending (deflection) load, it has a high strength against bending and can withstand a high load, and therefore the upper glass 1 and the lower glass There is no risk of the glass 2 cracking.

[0015]

As described above, according to the present invention, the blade edge surface of the glass serving as the base of the LCD is directed toward the compression surface side with respect to the bending (bending) of the glass itself caused by the static concentrated load. By adopting another structure, that is, a structure facing the LCD display surface side, it is possible to withstand a high load of about 4 to 5 times as compared with a structure in which the glass blade edge surface faces the pulling surface side (LCD
