の応用が期待されている。Conventional technology Ferroelectric liquid crystals are expected to be applied to large display capacity and high contrast display devices and high-speed optical shutters, which are impossible with conventional nematic liquid crystals, due to their high-speed response and bistability. .

ルを構成している。FIG. 4 is a sectional view of the entire liquid crystal device. Two glass substrates l on which transparent electrodes are formed are placed facing each other with the electrodes inside, and the peripheries of both glass substrates l are adhered using a sealing material 3.
A liquid crystal panel is constructed by sealing a ferroelectric liquid crystal 2 into a gap between one glass substrate and the other.

剤７で接続されている。Here, a transparent electrode terminal for external connection is exposed at the end of one glass substrate l of the liquid crystal panel. One end of the flexible substrate 6 is connected to the transparent electrode terminal via an anisotropic conductive adhesive 7, and the other end is connected to a drive circuit board 8 via an anisotropic conductive adhesive 7.

Further, a polarizing plate 4 and a polarizing plate 5 with a reflector are arranged on the front and back sides of the liquid crystal panel, respectively. Note that 11 is a driving LSI for driving the liquid crystal panel.

でしまい、保護効果はなかった。Problems to be Solved by the Invention In the conventional structure, when the surface is pressed or an impact is applied, the liquid crystal panel is deflected and the alignment is disturbed. This alignment disorder remains even after the external force is removed and the deflection of the liquid crystal panel returns to its natural state, resulting in a disadvantage that the bistability is reduced and the optical modulation function is significantly deteriorated. This phenomenon does not exist in devices using nematic liquid crystals, but is unique to devices using ferroelectric liquid crystals with a layered structure, and was a serious problem in practical application. In addition, as a means of protecting the liquid crystal panel, it is common to provide a protective plate on the liquid crystal panel, as shown in Japanese Patent Application Laid-Open No. 62-59922, but this method does not allow the surface of the panel to be accidentally touched. The frame that supports the panel has a protective effect against external forces applied to the panel surface, such as when pushed or when a falling object collides with the surface, but the frame that supports the panel protects against the force caused by the dropping of the liquid crystal device itself. The panel bent around the caulked part of the IO as a fulcrum, and there was no protective effect.

ある。The present invention solves the above problems, and aims to provide a ferroelectric liquid crystal device that can maintain a proper alignment state of ferroelectric liquid crystal for a long period of time even when an external force is applied. .

し固定したものである。Means for Solving the Problems In order to achieve this object, the ferroelectric liquid crystal device of the present invention comprises a liquid crystal panel by sealing ferroelectric liquid crystal between two substrates having transparent electrodes. A reinforcing member with high bending rigidity is installed on at least one side of the liquid crystal panel, and the liquid crystal panel and the reinforcing member are sandwiched and fixed between supports in a superposed state.
作用 前記手段による作用は次の様になる。action The effect of the above means is as follows.
外部圧力や落下衝突時の力が液晶パネルに加わり、パネ

ルは、曲げ剛性の大きい補強部材とともに挟持されてい
るため、強誘電性液晶装置全体の曲げ剛性が大きくなり

向乱れは大幅に抑制される。Even when stress is generated in the panel in the normal direction to the surface due to external pressure or force during a drop and collision, the liquid crystal panel is held together with reinforcing members with high bending rigidity, so the ferroelectric liquid crystal device The overall bending rigidity is increased, and bending deformation is less likely to occur in the liquid crystal panel, and as a result, alignment disorder is significantly suppressed.
実施例 以下、本発明の一実施例を図面を用いて説明する。Example An embodiment of the present invention will be described below with reference to the drawings.
（実施例１）
第１図に本発明の第１の実施例を示す０本実施例は、基
本的には前述の第５図に示した従来例と同し構成である

駆動回路基板８にかしめることにより、透明ガラス板２
０と液晶パネルとを駆動回路基板８に固定している。(Embodiment 1) FIG. 1 shows a first embodiment of the present invention. This embodiment basically has the same structure as the conventional example shown in FIG. The point is that a transparent glass plate 20 is used. A transparent glass plate 20 as a reinforcing member having sufficient bending rigidity is placed on top of the top surface of the liquid crystal panel, and both ends of the liquid crystal panel and transparent glass plate 20 are connected to a zebra rubber connector 12 and a frame lO having an L-shaped cross section. Hold it between the
In addition, the transparent glass plate 2 is crimped onto the drive circuit board 8 using the claw portion 10a provided at the lower end of the frame 10.
0 and a liquid crystal panel are fixed to a drive circuit board 8.
ここで透明ガラス板２０は材質及び形状を適正に選ぶこ
とにより曲げ剛性の大きなものとしている。The transparent glass plate 20 has high bending rigidity by appropriately selecting the material and shape.
このような構成にすれば、外部圧力や落下衝突時の力が
液晶パネルに加わりパネルに表面法線方向の応力が発生
した場合でも、液晶パネルは曲げ剛性の大きい補強部材
とともに挟持され、これにより液晶パネルのたわみ変形
が抑制されるため、液晶層の変形は防止され配向乱れは
発生しない。With this configuration, even if external pressure or force during a drop collision is applied to the liquid crystal panel and stress is generated in the panel in the normal direction to the surface, the liquid crystal panel will be held together with the reinforcing member with high bending rigidity, and this will prevent the liquid crystal panel from being damaged. Since the bending deformation of the liquid crystal panel is suppressed, deformation of the liquid crystal layer is prevented and alignment disorder does not occur.
さらに、液晶パネルと補強部材が直接接着されていない
ため、補強部材とガラス基板１材料の熱膨脹係数が異な
っても、補強部材を接着した場合の熱応力による配向乱

ある。Furthermore, since the liquid crystal panel and the reinforcing member are not directly bonded, even if the thermal expansion coefficients of the reinforcing member and the glass substrate 1 material are different, alignment disorder due to thermal stress will not occur when the reinforcing member is bonded, and the reinforcing member It is more effective than when it is glued.

補強部材として用いてもよい。In this embodiment, the reinforcing member of the transparent glass plate 20 is installed on the front surface of the liquid crystal panel, but the invention is not limited to this, and a reinforcing member made of another material may be installed, for example, on the back side of the liquid crystal panel. A reinforcing member made of a material with a large elastic constant such as metal or ceramic, or a reinforcing member in another shape with large bending rigidity may be installed on the surface of the material. A reinforcing member adhered or closely attached to this component may be used as the reinforcing member.
（実施例２）

ーサー２１を設置していた構成である。(Example 2) FIG. 2 shows a second example of the present invention. This example has a configuration in which a spacer 21 is installed between the liquid crystal panel and the transparent glass plate 20 in the case of Example 1. .
実施例１の構成による表示装置では液晶パネルと補強部
材が接触するために光が干渉して若干表示がみにくくな
るが、本実施例のようにスペーサー２１で一定間隔を保
てば光の干渉も起こさず非常に良好な表示が得られる。In the display device with the configuration of Example 1, the liquid crystal panel and the reinforcing member come into contact with each other, causing light interference and making the display somewhat difficult to see. However, if a constant distance is maintained with the spacer 21 as in this example, light interference can be prevented. A very good display can be obtained without any problems.
なお、このように液晶パネルと補強部材の間にスペーサ
ー２１を設置する構成は、本実施例に限定するものでな
