A liquid crystal driving device that supplies control signals including at least a polarity inversion signal for AC driving to an image signal line driving circuit, the polarity inversion signal includes polarity inversion pulses varied periodically at a prescribed period even in vertical blanking intervals. The last polarity inversion pulses at the last cycles in each of vertical blanking intervals are deleted.

A manufacturing process OF a thin film transistor is provided, in which occurrence of a dry spot and occurrence of an etch residue of an ohmic contact layer (nnulla-Si:H film) due to the dry spot are prevented in photoengraving process for patterning a semiconductor layer and the ohmic contact layer into an island, without any further treatment by any other apparatus. After forming the a-Si:H film 4a which forms the semiconductor layer of the TFT and the nnulla-Si:H film 5a which forms the ohmic contact layer, a N2 gas plasma discharge is continuously performed using the same plasma CVD apparatus, thereby forming a very thin silicon nitride film 6 having a hydrophilic property on a surface layer of the nnulla-Si:H film 5a.

A highly reliable liquid crystal display is obtained at a high yield rate by preventing disconnection of upper wiring (signal line) due to level difference due to lower wiring (scan line) in a region where the wirings (scan line and signal line) are intersected via an insulating film or the like in a TFT array substrate in which the TFT acting as a switching element is arrayed and formed into a matrix. A scan line (gate wiring) 2 has a pattern of including at least one bend 8a on both sides of the pattern in a region where the scan line (gate wiring) 2 and the signal line (source wiring) 6 are intersected.

In a process for chamfering substrates constituting a liquid crystal display device, it is made possible to prevent a static electricity from generating in a chamfering amount mark used in order to perform a highly accurate chamfering, and improve a chamfering accuracy. There is provided a structure in which a chamfering amount mark 7 formed in an end portion of a 1st substrate is formed so as to be electrically connected to a short wiring 10, and a connection between the chamfering amount mark 7 and extension wirings 9 which are another conductive wirings is performed, thereby discharging the static electricity to another conductive pattern. Incidentally, there is adopted a structure in which plural mark patterns 8b constituting the chamfering amount mark 7 are intended to be electrically connected by a connecting wiring 8a and, additionally, the connecting wiring 8a is extended to a short wiring 10 side.
