ABSTRACT:
This invention provides an active matrix type display device where an aperture ratio of each of pixels is improved and a storage value of a storage capacitor is secured. A driving power supply line overlaps a storage capacitor line in each of the pixels to reduce an area formed with the driving power supply line. The storage capacitor line is disposed to wind in zigzag along a plurality of pixel selecting TFTs arrayed in a row, thereby effectively utilizing a pixel area. Furthermore, a longitudinal direction of a contact connecting a source of the pixel selecting TFT and a gate of a driving TFT is disposed parallel to the storage capacitor line.
