A liquid crystal display device manufacturing method, including the steps of forming first-layer metal patterns in a display portion and a peripheral circuit portion of a first substrate; forming a first insulating film on the first-layer metal patterns; forming second-layer metal patterns on the first insulating film; and forming a color resin film on the second-layer metal patterns. The method also including the steps of patterning the color resin film to form color filters made of the color resin film in a pixel region of the display portion and to leave the color resin film in the peripheral circuit portion and forming a third-layer metal pattern on the color resin film in the peripheral circuit portion.

A thin film transistor matrix device comprises a transparent insulating substrate, a thin film transistor unit, a picture element unit, a storage capacitance unit, a gate terminal unit, and a drain terminal unit, the storage capacitance unit including a storage capacitance electrode formed on the transparent insulating substrate and formed of a metal layer of the same material as the gate electrode; a dielectric film formed on the storage capacitance electrode and formed of an insulating film common with the gate insulating film and a non-doped semiconductor layer of the same material as the semiconductor active layer; and a counter electrode formed on the dielectric film and formed of a doped semiconductor layer of the same material as the semiconductor contact layer and a metal layer of the same material as the source electrode and the drain electrode, the counter electrode being connected to the picture element electrode through a contact hole opened in a protecting film common with the passivation film. Thus, the fabrication process of the TFT matrix device can be simplified, and lower costs can be realized. Characteristic changes of the storage capacitance can be prevented, and yields and reliability can be improved.

An EL device having an electrode arrangement including first electrodes and at least one row of second electrodes intersecting the first electrodes and energized by a combination of the first and second electrodes. The second electrodes are divided into a plurality of sub-electrode portions. The electrode arrangement is such that the first electrodes each comprise a plurality of segments that are commonly-connected and intersect different sub-electrode portions. Another electrode arrangement is such that the first electrodes are arranged in a belt form and intersect different sub-electrodes portions in a meander manner. The EL device can be applied to an electrophotographic printing system as an optical system for forming a latent image. EL elements are repeatedly energized with the same data to give a sufficient intensity of light on a light sensitive medium, and deenergized for a time in which the intensity is decreased to a low level.

An improved method and apparatus to shift discharge spots produced in a gas discharge display panel, in accordance with given input information so that said discharge spots may be display-held in a desired display position. The shift operation is performed by supplying shift voltages sequentially to shift electrodes. A feature of this invention is to oscillate the discharge spots while they are being display-held in a display position, by supplying an operating voltage alternately to adjacent two shift electrodes during a display period. By oscillating the discharge spots during the display period, an operation margin is obtained which is equivalent to the operation margin available during the shift period, and operation of said display panel can be stabilized to avoid misfiring.
