A method of producing an impact resistant liquid crystal display, for a nematic liquid crystal display or a chiral smectic ferroelectric liquid crystal display, includes the steps of fixing a liquid crystal panel onto a panel fixing member so as to substantially expose the liquid crystal panel through an opening of the panel fixing member and disposing an elastic member along a periphery of the panel fixing member. The elastic member is affixed to a supporting member so as to define an almost closed space with the liquid crystal panel, the panel fixing member, the elastic member and the supporting member, whereby an air damping effect is created to suppress flexural deformation of the liquid crystal panel.

Impact resistant liquid crystal apparatus

A liquid crystal apparatus includes a liquid crystal cell comprising a pair of substrates each having thereon a transparent electrode with a thickness of 840 .ANG. or less, 1320-1680 .ANG., 1960-2470 .ANG. or 3180-3850 .ANG., and a liquid crystal layer disposed between the pair of substrates in a thickness of 10 microns or less; and a fluorescent light source comprising at least two types of fluophors having different emission peak wavelengths. The liquid crystal may preferably be a ferroelectric liquid crystal having a thickness of 5 microns or less. A dielectric film of, e.g., Ta.sub.2 O.sub.5 or TiO.sub.2 having a larger refractive index than the transparent electrode may be disposed.

Liquid crystal apparatus

A liquid crystal display apparatus is provided with a liquid crystal panel comprising a pair of substrates each provided with an electrode and a liquid crystal disposed between the pair of substrates. A supporting member having a frame supports the liquid crystal panel, and an elastic member for secures the liquid crystal panel in a floating state to the frame of the supporting member so as to define an almost closed space enclosed with the liquid crystal panel, the supporting member and the elastic member. A backlight illuminates the liquid crystal panel below the supporting member so as to define the almost closed space enclosed with the liquid crystal panel, the supporting member, the elastic member and the backlight.

Impact resistant ferroelectric liquid crystal apparatus

A ferroelectric liquid crystal apparatus includes: a ferroelectric liquid crystal cell including a pair of substrates each having an electrode and an alignment film thereon, the alignment films being respectively provided with uniaxial orientation axes (preferably those provided by rugging) which are provided in parallel and in the same oblique direction of from upper right to lower left or from lower left to upper right [from lower right to upper left or from upper left to lower right], a first polarizer having a transmission axis set within a region (I) defined by a clockwise (or counterclockwise) angle of 45.degree. from the direction of the uniaxial orientation axes, a second polarizer having a transmission axis set within a region (II) defined by a clockwise (or counter-clockwise) angle of 45.degree. from the direction forming right angles with the direction of the unilaxial orientation axes, and a mechanism for adjusting an angle of the ferroelectric liquid crystal cell standing up from a horizontal plane.

An image reading apparatus comprising a photosensor for receiving light from a light source through an original document, a wiring section for driving the photosensor, a circuit for driving the photosensor and for processing an output signal from the photosensor. The apparatus includes a first substrate having the photosensor and the wiring section thereon, and a second substrate having the circuit thereon and being separated from the first substrate. The second substrate is fixed above the first substrate.

Image reading apparatus comprising first and second substrates separated

There is a method and an apparatus for reading an image in which the light emitted from a light source through an original is converted into an electric signal by a photoelectric converting device and is outputted as an image singal. In this method, a compensation light is radiated onto the photoelectric converting device and thereby causing a compensation signal to be generated therefrom; this compensation signal is stored into a memory; an original image is then read; and the read signal is compensated by the compensation signal stored in the memory. The compensation light corresponds to each intensity of lights which are obtained through a reference original to be read and which are received by the photoelectric converting device. By use of this method in an original reading section of a facsimile apparatus or the like, an ununiformity and a variation in signal of each bit which is read by the photoelectric converting device are compensated, so that a stable output image signal can be derived.
