Liquid crystal display device

An active-matrix-driven LCD device comprising:

• a driver circuit and a display section formed on one substrate, each of thin-film transistors included in the driver circuit and display section has an active layer comprising polysilicon that has been formed by enhancing crystal growth thereof;
• wherein the driver circuit operates to write data of a same polarity to all pixels of an entire one-frame screen but write data of different polarities to different frames adjoining each other on a time base at a frame frequency of about 100 Hz or more;
• a gate bus line and an auxiliary-capacitance common line disposed in parallel and spatially spaced from each other, and
• a space between the gate bus line and the auxiliary-capacitance common line corresponding to an identical pixel forms a light transmitting portion usable for display.

An active-matrix-driven LCD device comprising:

• a driver circuit and a display section, wherein the driver circuit operates to write data of a same polarity to all pixels of an entire one-frame screen but write data of different polarities to different frames adjoining each other on a time base, and
• a capacitance provided between pixel electrodes adjoining each other along a source bus line in the display section, said capacitance including an inter-electrode capacitance between adjacent pixel electrodes and/or a capacitance given by an overlap of an electrically conductive light-shield layer with the adjacent pixel electrodes, said conductive light-shield layer being in electrical communication with a drain of a thin film transistor and disposed at least partially under the adjacent pixel electrodes with an insulating film interposed therebetween;
• and
• wherein a space between the pixel electrodes adjoining each other in a direction in which the source bus line extends is about 15% or less of a length(s) along the source bus line of each of the pixel electrodes so that the inter-electrode capacitance between the adjoining pixel electrodes is obtained.
