Provided is an image display apparatus including: a vacuum container having an electron source enclosed therein for displaying an image; an ion pump communicating with the vacuum container for discharging air therefrom and decreasing pressure therein; and a resistor connected in series with the ion pump with respect to a power supply for driving the ion pump. Even if internal resistance of the ion pump undergoes order-of-magnitude changes according to its operating state, current consumption can be suppressed and the ion pump can be driven efficiently.

An image display apparatus is provided with a vacuum chamber consisting of an electron source substrate and an image display substrate, and an ion pump which is attached to an electron-emitting substrate or the image display substrate and exhausts air from the vacuum chamber by the action of a magnet, wherein the magnet is attached and fixed to the substrate to which the ion pump has been attached. Thereby, the image display apparatus prevents the magnet from applying an excessive force to the ion pump by its weight, and acquires a stable structure without causing a vacuum leak.

In order to be capable of high-precision gas measurement and evaluating influences of a gas on an electron source, and to predict a life of an image display device with high precision for a short period of time, there is provided a sealed container which is capable of maintaining an inside thereof to a lower pressure than an atmospheric pressure, and is used for an image display device including in the inside: a phosphor; an electron-emitting device for causing the phosphor to emit light; and a getter, the sealed container including an exhaust pipe having a breakable vacuum isolating member on at least one side of the image display device. Accordingly, after the exhaust pipe is connected to a gas measuring apparatus, by vacuum-exhausting the gas measuring apparatus and breaking the breakable vacuum isolating member, it is possible to perform a gas measurement on the image display device by using a measuring chamber having an orifice having a known conductance and installed in part of an exhaust channel of the gas measuring apparatus for vacuum-exhausting the image display device.

摘要:
A liquid crystal device is constituted by a pair of electrode plates and a liquid crystal composition disposed between the electrode plates. At least one of the electrode plates comprises a light-transmissive substrate, a plurality of electrodes including principal electrodes and auxiliary electrodes supported on the light-transmissive substrate, and an insulating layer. Each auxiliary electrode is disposed between an associated principal electrode and the light-transmissive substrate so as to be electrically connected with at least a part of the associated principal electrode, and the auxiliary electrodes being disposed with spacings therebetween which are filled with the insulating layer. The liquid crystal composition comprises at least one species of a fluorine-containing mesomorphic compound comprising a fluorocarbon terminal portion and a hydrocarbon terminal portion, the terminal portions being connected with a central core, and having smectic mesophase or latent smectic mesophase. The combination of the above specific cell structure and the specific liquid crystal composition is effective in improving display quality (e.g., contrast) while minimizing a voltage waveform deformation.
