Image display device

An image display device wherein

• a plurality of drain signal lines extended in a first direction on a substrate,
• a plurality of gate signal lines extended in a second direction and intersected said plurality of drain signal lines to define pixels,
• each of the pixels includes a thin film transistor and a pixel electrode,
• said plurality of drain signal lines are divided into a group of upper drain sinnal lines and a group of lower signal lines which end portions are separated from each other at approximately center portions of the pixels,
• upper video signals are supplied to said upper drain signal lines from a first video sianal drive circuit,
• lower video signals are supplied to said drain signal lines from a second video signal drive circuit,
• a thin film transistor in a respective pixel, which transmits the upper video signal of one respective upper drain signal line, is operated in response to a scanning signal from a respective gate signal line arranged at a upper side with respect to the pixel, and
• a thin film transistor in a respective pixel, which transmits the lower video signal of one respective lower drain signal line is operated in response to a scanning signal from a respective gate signal line arranged at a lower side with respect to the pixel.
