ルの断面図を図3に示す。2. Description of the Related Art Conventionally, glass, quartz, and single crystal silicon, which have been used as a substrate of a liquid crystal panel of a liquid crystal display device, are apt to cause chipping (chip) with a slight impact. Therefore, for example, JP-A-5-165013,
The impact resistance improving means as disclosed in Japanese Patent No. 165,014 has been taken. A cross-sectional view of such a conventional liquid crystal panel is shown in FIG.

が用いられている。In FIG. 3, reference numeral 1 denotes a liquid crystal panel, which is constructed by sandwiching a liquid crystal 6 between a drive circuit board 3 and a counter substrate 4. Reference numeral 2 denotes a protective frame, which is an elastic body 7 with respect to the liquid crystal panel 1.
Are integrated through. Therefore, when an impact such as a drop is applied, the impact is not directly transmitted to the liquid crystal panel 1 by the protective frame 2, and the impact force is mitigated by the elastic body 7. The elastic body 7 is not particularly necessary for a large-screen liquid crystal display device or, conversely, for a small-screen liquid crystal display device such as a viewfinder, and only a protective frame made of resin or sheet metal is used.

ている。On the other hand, also in the liquid crystal display device, the definition of the screen has been improved, and an active matrix drive type liquid crystal display device in which a thin film transistor (TFT) is arranged for each pixel has been generalized. In a liquid crystal panel of this type, when a transmissive liquid crystal display device is formed by using an opaque substrate such as single crystal silicon as a drive circuit substrate, a liquid crystal drive element layer is formed on the substrate via a transparent insulating layer. , The substrate in the display region is removed by etching to make the display region transparent. Therefore, the display area becomes a thin membrane composed of the transparent insulating layer and the liquid crystal driving element layer. Such a liquid crystal panel is disclosed in, for example, Japanese Patent Laid-Open No. 3-194115.

【発明が解決しようとする課題】上記したようなメンブ

を設けた場合、図3に示したパネルよりは落下等の衝撃

ブレンの破壊が生じる場合がある。特に、角部が下にな
って落下した場合に破損し易い。When a liquid crystal panel having a membrane as described above is provided with a protective frame as shown in FIG. 3, it is more resistant to impacts such as dropping than the panel shown in FIG. The impact force transmitted through the substrate may break the membrane. In particular, it is easy to be damaged when the corner is down and it falls.
【0006】また、メンブレンを有する液晶パネルは外
部からの振動の影響を受け易い。振動が弾性体を通して
液晶パネルに伝わると、先ず、画面が振動するという問
題を生じる。特に、振動の振幅が大きく、60Hz以下
の場合には、視覚的に問題がある。A liquid crystal panel having a membrane is easily affected by external vibration. When the vibration is transmitted to the liquid crystal panel through the elastic body, first, there occurs a problem that the screen vibrates. In particular, when the amplitude of vibration is large and 60 Hz or less, there is a visual problem.

振動が伝わることによってセルギャップに不均一な部分

時に、液晶自体も振動に従って移動をくり返すことにな
り、液晶の配向性に問題を生じる。Since the cell gap of the liquid crystal panel is realized by giving an appropriate tension to the membrane, vibration is transmitted to the film surface to form a non-uniform portion in the cell gap, resulting in deterioration of the image quality itself. Will end up. At the same time, the liquid crystal itself repeats its movement according to the vibration, which causes a problem in the orientation of the liquid crystal.

う。Further, when the membrane vibrates, the amount of gas passing through the membrane increases, which causes bubbles in the cells. Furthermore, the tension applied to the membrane causes the transparent insulating layer forming the membrane to gradually crystallize and devitrify, which is accelerated by vibration.

The purpose is to prevent the deterioration of display characteristics and the reliability of the device due to these external forces.

グ率106 Pa以下の弾性体を介して保護枠を設けたこ
とを特徴とする。The present invention is a liquid crystal display device which solves the above-mentioned problems and is characterized in that a liquid crystal panel is provided with a protective frame through an elastic body having a Young's modulus of 10 6 Pa or less. To do.

ができる。本発明に係る弾性体の軟らかさの程度は以下
のようにして見積もることができる。According to the present invention, the liquid crystal panel is covered with a strong protective frame which does not easily deform, and at the same time a soft elastic body is interposed between the protective frame and the liquid crystal panel to absorb the shock transmitted to the liquid crystal panel. The influence can be prevented. The degree of softness of the elastic body according to the present invention can be estimated as follows.

えば、ヤング率Eを通常のビューファインダー用液晶表
示装置(M=3g、L=2cm、t=3mm)で見積も
ると、おおよそ103 Pa程度となる。First, assuming that the drop height h of the liquid crystal display device is about 1 m and the weight of the device is Mkg, the drop energy is Mgh≈9.8 Mjoul. It is assumed that the size of the liquid crystal panel is Lm × Lm, the thickness is tm, and the thickness of the elastic body is am, and the liquid crystal panel has fallen from a corner portion of the display device. In this case, assuming that the elastic body can be deformed up to a / 2 m,
The internal energy Ujoul absorbed by the elastic body is U ≧ (4L × t) × (1/2) (1/2) 2 E = (1 /
2) LtE. Since this may be equal to or more than the drop energy, an elastic body as soft as possible that satisfies E> 19.6 M / Lt may be used. For example, when the Young's modulus E is estimated with a normal viewfinder liquid crystal display device (M = 3 g, L = 2 cm, t = 3 mm), it is about 10 3 Pa.

うにa,ρ,Eを選択すれば良い。The vibration of the liquid crystal cell can be prevented by selecting the thickness and Young's modulus of the elastic body. That is, the amplitude of vibration can be reduced by reducing the thickness am. Although the thickness depends on the device, about 1 mm is sufficient. Further, in order to reduce the vibration of 60 Hz or less, the natural frequency of the longitudinal wave of the elastic body is set to 60 Hz or more. The natural frequency ν v Hz is
When the length is am, the density is ρkg / m 3 , and the Young's modulus is EPa, it can be expressed as ν v = (E / ρ) 1/2 / 2a. Therefore, a, ρ, and E should be selected so that ν v > 60 Hz.

Make sure the natural frequencies do not match.
【0015】前者の手段は、弾性体の厚さを極力薄くす

いることである。The former means is to reduce the thickness of the elastic body as much as possible and to use a soft elastic body so that vibrations can be easily damped.

The longitudinal and transverse wave natural frequencies ν v , ν w , and Hz of the membrane with 0 kg / m 3 , residual stress TPa, and Young's modulus EPa are expressed as follows.

のが好ましい。Ν v = (E / ρ 0 ) 1/2 / 2w ν w = (T / ρ 0 ) 1/2 / 2w (influenced by liquid crystal) Generally, the natural frequency of the longitudinal wave of the membrane is sufficient. It's expensive, so it's not a problem. However, the transverse wave is low and may be close to the natural frequency of the elastic body, and more accurately, it is preferable to actually measure the natural frequency of the membrane and the elastic body to deal with it.

Does not happen. Further, the total thickness of the elastic body 7 and the protective frame 2 is 1.2 mm, which does not particularly increase the mounting size of the device.
