Abstract: In a liquid crystal display device of an active matrix type, at first, an initialization signal voltage having a voltage value equal to or higher than the maximum voltage value of a display signal is applied to display pixels in a signal application period in a field period. The display signal is thereafter applied. As a result, the change amount of the voltage applied to liquid crystal due to the field-through voltage in relation to a gate pulse can be arranged to be substantially constant, and can always be cancelled by a common electrode voltage. Occurrence of flicker and seizure phenomena can be thereby restricted so that the display quality can be improved.

Abstract: An active matrix display panel includes a plurality of pixel electrodes formed in a matrix manner, a plurality of switching elements connected with these pixel electrodes, a plurality of scan lines for supplying a scan signal to thin film transistors, and a plurality of data lines for supplying a display data signal. Components except for the pixel electrodes are covered with an overcoat film. Since a contact hole extending through this overcoat film and a contact hole extending through the overcoat film and a gate insulating film are simultaneously formed, a jumper line for connecting a disconnected portion of a protect ring, a surface layer of a data line connecting pad, and a line protecting film are formed at the same time as the pixel electrodes are formed. This reduces the number of fabrication steps. Components such as the data line and source and drain electrodes are formed by a three-layered structure of Cr(Chromium)/Al(Aluminum)/Cr(Chromium).

Abstract: An active matrix substrate includes a line layer formed of an Al-based metal layer and a part of which is exposed through a contact hole formed in an insulating film. In the active matrix substrate, pixel electrodes are formed of an ITO film on the insulating film, and a jumper line for connecting a disconnected portion of a protect ring, a surface layer of a data line connecting pad, and a line protecting film are formed at the same time as the pixel electrodes are formed. This reduces the number of fabrication steps. The ITO film is patterned by dry etching due to reactive ion etching using a mixed gas of a hydrogen halide gas and an inert gas, with the temperatures of the center portion and peripheral portion of the substrate substantially equalized to each other.
