摘要： PROBLEM TO BE SOLVED: To protect the channel region of a semiconductor film against radiation damage when patterning by plasma etching.SOLUTION: An ohmic contact layer-forming film 25 of n-type amorphous silicon is deposited on the top surface of a semiconductor film-forming film 21 of intrinsic amorphous silicon, containing a first channel protective film 5 of silicon nitride and a second channel protective film 6 of shading metal. The ohmic contact layer-forming film 25 and the semiconductor film-forming film 21 are subjected to plasma etching for patterning, using resist patterns 26 and 26 and the second channel protective film 6 as masks. In this case, radiations, such as ultraviolet rays, X-rays, etc., emitted from the plasma of an etching source can be prevented by the second channel protective film 6 of shading metal, so that a channel region of the semiconductor film 4 can be protected against radiation damage. Moreover, the second channel protective film 6 of shading metal is separated into two halves in a succeeding process.

摘要： PROBLEM TO BE SOLVED: To prevent degradation of display quality, even if a length of wiring for electrically connecting a gate line 11 with a gate driver differs by gate line. SOLUTION: A display device is configured such that a length of a gate routing wire 18 for electrically connecting the gate line 11 for transmitting a scanning signal in a thin film transistor 10 formed at a display pixel with a gate output terminal 19 is different by gate line 11.

Thereby, each gate routing wire 18 has mutually equal time constant from the gate line 11 corresponding to the gate routing wire 18 to the gate output terminal 19 corresponding to the gate routing wire 18.

摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display device which is provided with routing lines connected to scanning lines above and below a gate insulating film in parallel, the lower-layer routing lines being minimized in pitch and upper-layer routing lines being made not apt to short-circuit to each other even if a pattern defect (unnecessary film residue) is caused when the upper-layer routing lines are formed by photolithography.
SOLUTION: An interval L of the upper-layer routing lines 7 is set to (2W+D) obtained by adding an interval D of the lower-layer routing lines 6 to the double of a line width W of the lower-layer routing lines 6. The interval L of the upper-layer routing lines 7 which is thus set to 2W+D is much larger than the interval D of the lower-layer routing lines 6, so the pitch (W+D) of the lower-layer routing lines 6 is minimized and even if the pattern defect (unnecessary film residue) is caused when the upper-layer routing lines 7 are formed by photolithography, the upper-layer routing lines 7 are made not apt to short-circuit to each other.
