TFT SUBSTRATE FOR DISCHARGING STATIC ELECTRICITY TO A STATIC ELECTRICITY DISCHARGING LINE IN SPITE OF THE INFLOW OF THE STATIC ELECTRICITY THROUGH A REPAIR LINE

摘要

PURPOSE: A TFT(Thin Film Transistor) substrate is provided to discharge static electricity to a static electricity discharging line in spite of the inflow of the static electricity through a repair line, thereby preventing damage of a display region of the TFT substrate, by forming the repair line to cross over the static electricity discharging line at a region before a crossing region of the repair line and a data line. CONSTITUTION: A plurality of the first signal lines(121) and a plurality of the second signal lines(171) are formed over a substrate. The first signal lines cross over the second signal lines to designate a plurality of pixels in a display region. A plurality of repair lines(127) and a plurality of static electricity discharging lines(172) are formed at the peripheral region surrounding the display region over the substrate. The repair lines cross over the second lines. The static electricity discharging lines cross over the repair line at a region before a crossing region of the repair line and the second signal line. A plurality of the first diodes are electrically connected to the repair lines and the static electricity discharging lines.
