摘要： A head chip has a substrate having a first main surface and a second main surface opposite the first main surface. First partition walls are disposed on the first main surface of the substrate in spaced apart relation at a preselected interval to form first channels each for receiving ink. Second partition walls are disposed on the second main surface of the substrate in spaced apart relation at a preselected interval to form second channels each for receiving ink. Electrodes are connected to side walls of the first and second channels and are driven by a voltage signal to deform the side walls to vary the volume in the first and second channels to thereby eject ink from the first and second channels.

摘要： A thin film transistor array for a liquid crystal display device is produced by simultaneously forming gate electrodes and picture element electrodes; forming islands of a layered structure comprised of a gate insulating film, a thin semiconductor film and a light shielding film in a single masking step; and forming the gate, source and drain wiring metals in contact windows by the "lift-off" technique after using a resist film for opening the contact windows. Only three masking steps are required thereby enabling an increase in production yield and a lower production cost as compared to conventional techniques which typically require seven masking steps.
