Patent ID: 8686980

Claim:
An array substrate comprising: an insulating substrate having a display area and its surrounding area; switching elements arranged in a matrix manner on the insulating substrate; pixel electrodes arranged in a matrix manner in the display area of the insulating substrate and being connected to the switching elements; and driving circuits for driving the switching elements, the driving circuits being provided in the surrounding area and comprising a plurality of column groups arranged in a direction from an end side of the insulating substrate toward the display area, wherein each of the column groups has a longitudinal side along the end side of the insulating substrate and comprises a plurality of row groups corresponding to rows of the pixel electrodes arranged in a matrix manner and each having a plurality of driving elements; a plurality of trunk lines extending along the end side of the insulating substrate in the surrounding area, at least one of the trunk lines being provided between the adjacent column groups; branch lines being provided in the surrounding area and each connecting the trunk line to the driving element; and junction lines each extending from the branch line of interest to electrically connect the branch line of interest to the driving element provided in the row group different from the row group where the driving element connected to the branch line of interest is provided.
