ACTIVE MATRIX SUBSTRATE AND DISPLAY DEVICE

摘要

Disclosed is an active matrix substrate that can minimize variations in signal voltages between pixel electrodes. Said active matrix substrate is provided with: a plurality of pixel electrodes arranged in a matrix on top of an insulating substrate; and source lines that each extend in the column direction so as to overlap both of two pixel electrodes that are adjacent in the row direction. The pixel electrodes and the source lines are formed on different layers, with an insulating film therebetween. Each source line has a main section and extension sections that extend outwards on both sides of the main section. The extension sections comprise a transparent conductive material.
