A display apparatus includes two substrates (10, 15) having electrodes, respectively, and a liquid crystal layer (17) arranged between the two substrates. One of the two substrates includes a plurality of linear luminous sources (Y₁, Y₂, ..., Y n ) ranged in parallel each other, a plurality of linear electrodes (X₁, X₂, ..., X m ) ranged in parallel each other and the linear electrodes being crossed with the plurality of linear luminous sources, and a plurality of photoconductive layers (13) provided at crossed positions of the plurality of linear luminous sources and the plurality of linear electrodes, the photoconductive layers serving to perform switching operation in response to light applied from the plurality of linear luminous sources. The liquid crystal layer has pixels to be driven by a signal applied through the plurality of linear electrodes and the plurality of photoconductive layers.
摘要:
A carbon electrode is prepared by the steps of subjecting a hydrocarbon to vapor phase pyrolysis to form a pyrolytic carbon having a specific X-ray diffraction peak half-width; contacting the pyrolytic carbon with lithium vapor to obtain a lithium-intercalated pyrolytic carbon; and forming the lithium-intercalated pyrolytic carbon into an electrode. The pyrolytic carbon is preferably formed on a substrate, especially an iron group metal, and the electrode may be used with advantage as cathode in a non-aqueous secondary battery.

摘要:
A method for the manufacture of a pyrolytic graphite with high crystallinity comprises the deposition of graphite directly onto a catalytic substrate by thermal decomposition of a carbon-containing material at low temperatures. Also disclosed is an electrode comprising graphite as an active material and an electrode substrate as a current collector unified, said graphite being pyrolytic graphite that is deposited on a metal electrode substrate with catalytic properties so as to cover said metal electrode substrate by the said method. Further disclosed is a battery comprising a pair of positive and negative electrodes, at least one of which is made of graphite as its electrode active material.
