Description of the invention (1) Background of the invention The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device for controlling poor display caused by external impacts transmitted through and mounting a mounting portion of a machine. Liquid crystal display devices are widely used as high-definition and color display devices for notebook computers or display monitors. The liquid crystal display device is well-known as a simple matrix type liquid crystal panel using a liquid crystal panel that holds a liquid crystal layer by using a substrate having a pair of parallel electrodes formed on each inner surface to cross each other, and a pair of substrates. One of the active matrix type liquid crystal display devices includes a liquid crystal panel with a switching element selected for use in a pixel unit. Active matrix liquid crystal panels, as represented by the twisted nematic (τ N) method, include the so-called vertical electric field method (generally referred to as T) of a liquid crystal panel in which an electrode group for pixel selection is formed on a pair of upper and lower individual substrates. N method), and a so-called lateral electric field method (generally referred to as an IPS method) using a liquid crystal panel in which an electrode group for pixel selection is formed only on one of a pair of upper and lower substrates. The former T.N LCD panel is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs in a pair of two substrates (the first substrate (lower substrate) and the second substrate (upper substrate)). For example, it is oriented by twisting at 90 °, and polarizers are arranged on the outer surface of the upper and lower substrates of the liquid crystal panel so as to intersect in the direction of the absorption axis, and two polarizing plates are laminated so that the absorption axis on the incident side is parallel or crosses the rubbing direction. When no voltage is applied to this TN-type active matrix liquid crystal panel, the incident light is linearly polarized by the incident-side polarizing plate, and this linearly polarized light is along the liquid -4- This paper is in accordance with the Chinese National Standard (CNS) A4 specification (210 X 297 mm) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 574550 A7 _ B7 V. Description of the invention (2) Twisting propagation of the crystal layer, the transmission axis of the exit-side polarizer is consistent with the azimuth of the linearly polarized light All the linearly polarized light is emitted and becomes a white display (so-called normally-on mode). In addition, when a voltage is applied, the direction (pointing) of the unit vector of the average orientation direction of the liquid crystal molecular axes constituting the liquid crystal layer is oriented perpendicular to the substrate surface, and the azimuth of the linearly polarized light on the incident side is not changed. Because the absorption axis of the plate is the same, it becomes a black display (refer to the "Basics and Applications of Liquid Crystal" issued by the Industrial Survey Association in 1991). On the other hand, an electrode group or electrode wiring group for pixel selection is formed only on one of a pair of substrates, and a voltage is applied between adjacent electrodes (between the pixel electrode and the counter electrode) on the substrate so that the liquid crystal layer is in contact with In an IPS-type liquid crystal panel with a direction switch having a parallel substrate surface, when no voltage is applied, a polarizing plate is arranged in a black display (so-called normally closed mode). In the initial state, the liquid crystal layer of the IPS-type liquid crystal panel is uniformly aligned parallel to the substrate surface. Moreover, in a plane parallel to the substrate, the orientation of the liquid crystal layer is parallel to the electrode wiring direction or has a certain angle when no voltage is applied. When the voltage is applied, the direction of the liquid crystal layer is compared with the direction when no voltage is applied. When the electrode wiring direction is inclined by 45 °, the liquid crystal layer when the voltage is applied is rotated by the azimuth of polarized light just like a 1/2 wavelength plate. At 0 °, the transmission axis of the exit-side deflector is the same as the azimuth of the polarized light, and it becomes a white display. This IPS-type LCD panel has a small change in hue or contrast in the viewing angle, and has a feature that can achieve a wide viewing angle (refer to Japanese Patent Publication No. 5-505247 (Patent No. 2743293)) ------- ---- Install ------ Order --------- (Please read the notes on the back before filling in this 15 ^ This paper size applies to China National Standard (CNS) A4 specifications (210 X 297 (Mm) -5- 574550 Α7 B7 5. Description of the invention (3) 〇 In the full-colorization of the liquid crystal display device using the above-mentioned various liquid crystal panels, the color filter method is the mainstream.

The upper frame SHD is formed by a metal plate and the lower frame MC Α 挟 is generally molded by plastic. The liquid crystal display device MDL shown in FIG. 3 is mounted on the construction machine in the above-mentioned side-mounting method. This side-mounting method has screw holes T Η on the side of the liquid crystal display device MDL from the upper frame SHD to the lower frame MC Α, This screw hole is installed between the screw hole located in the display part (usually the cover part) of a construction machine, such as a personal computer, by a screw.

The reinforcing member S T has a hinge Η N G for attaching the cover C A S E to the main body of the personal computer which is equipped with a keyboard or the like. Moreover, in this example, although the reinforcing member S T is a sub-shape of the open arms having the left and right sides of the liquid crystal display device MDL, it is not only this shape, but the left and right sides are individually formed as separate arms.

The backlight B L is formed by laying a reflection plate ALS and a reflection sheet RFS on a concave portion ALV formed in most of the central area of the lower frame MC A so that the light guide plate G L B is positioned on the upper portion and an optical plate 0 p s is placed on the upper portion. This optical plate OPS is held between the upper surface of the bank portion DAM formed around the lower frame MCA and the liquid crystal panel PNL. The insert I N S is buried in the bank DAM of the lower frame MCA, and the upper frame S H D has screw holes T Η. The screw holes of the reinforcing member S T are locked by screws S C to be fixed as the insert I N S of the screws. In this fixing structure, an impact is applied from the outside, and the reinforcing member is transmitted to the lower frame of the liquid crystal display device through the screws of the mounting portion. As a result, there is a problem that corrugated display defects occur on the display surface of the liquid crystal panel. Fig. 16 is a cross-sectional model diagram near the line B-B of Fig. 14 to explain the cause of the occurrence of corrugated display defects that occur on the display surface of the liquid crystal panel. The liquid crystal display device M D L is fixed by a reinforcing member S T with a screw S C penetrating therethrough, and is fixed to an insert I N S embedded in a frame MCA below it. At this time, for example, an impact when a keyboard of a personal computer constituting the device is hit is transmitted by the reinforcing member S T to the bank portion D AM of the frame MC A below the liquid crystal display device MD L.

In addition, such a display failure is not limited to those who are mounted sideways. Even if the surface side of the liquid crystal display device MDL is mounted on the mounting machine, the Δnd part of the liquid crystal panel PNL changes due to external impact. In the structure, the same happens. In addition, such display failure is liable to occur in a frame structure that has been thinned in recent years.

Therefore, the conventional corrugated display failure does not occur. In addition, although the above-mentioned chamfered portion is suitable to be applied to the entire area in the length direction of the transverse wall, in the case where the mechanical strength of the mounting portion with the reinforcing member is reduced, it can also be formed by avoiding the embedded portion of the insert.
