Abstract:
1. An active matrix substrate, comprising: a plurality of first lines formed parallel with one another in a display area; a plurality of second lines formed parallel with one another so as to cross the first lines in the display area; and a plurality of terminals formed in a mounting area, wherein the plurality of first lines, having first ends on one side and second ends on the other side, include a first group of the first lines that are adjacent to one another and whose first ends serve as input ends for a driving signal, and a second group of the first lines that are adjacent to one another and whose second ends serve as input ends for a driving signal, the active matrix substrate further comprising: a first lead-out line that connects the first ends of the first lines of the first group with the terminals; a second lead-out line that connects the second ends of the first lines of the second group with the terminals; first switching elements connected with the second ends of the first lines of the first group; second switching elements connected with the first ends of the first lines of the second group; a third lead-out line that connects the first ends of the second lines with the terminals; third switching elements connected with the second lines or the third lead-out line; a first switching element control line through which an ON/OFF control signal can be fed to the first switching elements; a second switching element control line through which an ON/OFF control signal can be fed to the second switching elements; and a third switching element control line through which an ON/OFF control signal can be fed to the third switching elements; a first inspection line through which an inspection signal can be fed to the first switching elements that are not adjacent to one another, among the first switching elements connected with the first lines of the first group; a second inspection line connected with the first switching elements that are not connected with the first inspection line and are not adjacent to one another, among the first switching elements connected with the first lines of the first group, so that an inspection signal can be fed to said first switching elements; a third inspection line through which an inspection signal can be fed to the second switching elements that are not adjacent to one another, among the second switching elements connected with the first lines of the second group; a fourth inspection line connected with the second switching elements that are not connected with the third inspection line and are not adjacent to one another, among the second switching elements connected with the first lines of the second group, so that an inspection signal can be fed to said second switching elements; a fifth inspection line through which an inspection signal can be fed to the third switching elements that are not adjacent to one another, among the third switching elements connected with the second lines; and a sixth inspection line connected with the third switching elements that are not connected with the fifth inspection line and are not adjacent to one another, among the third switching elements connected with the second lines, so that an inspection signal can be fed to said third switching elements.
