摘要： 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.

摘要： 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). This reduces the contact resistance between the source electrode and the pixel electrode and also reduces the resistance of the data line. The sectional shape of, e.g., the data line made of the multilayered film is so formed as to be readily covered with the overcoat film. This improves the reliability.

A region in the auxiliary capacitance electrode that overlaps with the gate electrode has a length in a direction parallel to a channel length direction of the thin-film transistor that is shorter than a length of the gate electrode in this direction and longer than a length of the anti-etching layer in this direction.

摘要： According to the present invention, a channel protection film is formed a little smaller in area than the gate electrode formed of a shielding metal film. A semiconductor thin film is formed such that the thickness is set not less than 200 Å and less than 400 Å. A distance A between the edge of the gate electrode in the channel length direction and the edge of the channel protection film is set around 0.2-1.2 &mgr;m, and a distance B between the edge of the gate electrode in the channel width direction and the edge of the channel protection film is set around 1-2 &mgr;m. With this constitution, the leak current of the thin film transistor due to the light irradiation can be reduced.
