摘要:
An electrode plate, suitable for constituting a liquid crystal device, includes at least a light-transmissive substrate, a plurality of metal electrodes disposed on the light-transmissive substrate and with spacings therebetween, and an insulating layer disposed at the spacings. Each of the metal electrodes includes a first layer, disposed on the light-transmissive substrate comprising a metal or alloy selected from the group consisting of titanium, chronium, molybdenum, tungsten, aluminum, tantalum and nickel, a second layer comprising copper or silver dispersed on the first layer; and a third layer comprising a metal or alloy selected from the group consisting of molybdenum, tantalum, tungsten, titanium, chromium, nickel, aluminum and zinc and disposed on the second layer. The electrode plate is effective in providing a liquid crystal device with good display qualities, a durability and a productivity through improvements in an adhesiveness to the light-transmissive substrate and an antioxidizing property of the metal electrodes.
摘要:
An electrode plate is formed by a substrate and a plurality of patterned electrodes formed on the substrate. Each patterned electrode has a laminate structure including a first layer of nickel metal formed on the substrate and a second layer of copper formed thereon. The electrode plate may be prepared by a process including a step of etching such a multilayer metal electrode-forming film formed on a substrate by spraying an etchant downwardly and uniformly onto the substrate while rotating the substrate at a rotation speed sufficient to allow quick liberation of the etchant from the substrate. The metal electrodes can be formed with a good adhesion onto the substrate and with good accuracies of width and thickness. By incorporating the electrode plate as a pair of substrates sandwiching a liquid crystal, a liquid crystal device showing free from transmission delay and rounding of voltage waveforms can be provided.

Each patterned electrode has a laminate structure including a first layer of nickel metal formed on the substrate and a second layer of copper formed thereon. The electrode plate may be prepared by a process including a step of etching such a multi-layer metal electrode-forming film formed on a substrate by spraying an etchant downwardly and uniformly onto the substrate while rotating the substrate at a rotation speed sufficient to allow quick liberation of the etchant from the substrate. The metal electrodes can be formed with good adhesion onto the substrate and with good width and thickness accuracy.

An electrode plate, suitable for constituting a liquid crystal device, includes a light-transmissive substrate, a plurality of first electrodes disposed on the light-transmissive substrate and a plurality of second electrodes disposed on the first electrodes. Each first electrode comprises a layer of metal nitride and is electrically connected with an associated second electrode, and each second electrode comprises a transparent electrode. The electrode plate is effective in improving an adhesiveness between the first electroded and the light-transmissive substrate and an antioxidizing property of the first electrodes while ensuring a good electrical connection state between the first electrodes and the second electrodes.

An etching process includes the steps of: preparing an etchant containing ferric chloride and an anticorrosive agent for Cu, and etching with said etchant a multi-layer metal structure including a Cu layer and an Ni layer. The etchant may preferably further contain ferrous chloride. The etching process is effective in making etching rates of the respective substantially equal, thus suppressing occurrence of burr portions of the Ni layers.

Provided is a method of manufacturing an organic light emitting device including the step of forming an electron injection layer. The step of forming the electron injection layer includes the steps of: vaporizing in a container a dopant material as a raw material of a dopant; causing the vaporized dopant material to pass a heated medium between the container and the substrate; and forming the organic compound into the electron injection layer. According to the method the organic light emitting device which has high electron injection efficiency and can be driven at a low voltage can be obtained.
