Patent ID: 8586987

Claim:
An active matrix substrate comprising an insulating substrate, the insulating substrate having a display region including a plurality of pixel TFT elements and reflective pixel electrodes, the insulating substrate having a peripheral region, surrounding the display region, which includes a plurality of driving TFT elements for driving the pixel TFT elements, the peripheral region further including branch wires electrically connected to the driving TFT elements and first stem wires, electrically connected to the branch wires, through which external signals are inputted, the pixel TFT elements and the driving TFT elements including a gate electrode layer and a source and drain electrode layer, the reflective pixel electrodes being formed by a reflective pixel electrode layer that is different from the gate electrode layer and the source and drain electrode layers, the peripheral region having at least one second stem wire formed therein to extend along long sides of the first stem wires, the first stem wires, the at least one second stem wire, and the branch wires being formed by different layers selected from among the gate electrode layer, the source and drain electrode layer, and the reflective pixel electrode layer, respectively, wherein the display region further includes transparent pixel electrodes electrically connected to the pixel TFT elements; and the first and at least one second stem wires and the branch wires are electrically connected to each other through connection conductors formed by a same layer as the transparent pixel electrodes.
