ABSTRACT:
It is an object of exemplary embodiments of the invention to realize a decrease in size and increase in accuracy with a simple structure and to perform high-quality display. According to exemplary embodiments of the invention, data lines, scanning lines, thin film transistors, storage capacitors, shield layers, and pixel electrodes are provided on a substrate. Each shield layer includes a first conductive light-shielding film which is formed in a non-open area between pixels using a plurality of interlayer insulating films disposed on a storage capacitor as an underlying layer and is electrically connected to a fixed-potential side electrode of the storage capacitor through a contact hole integrally penetrating the plurality of interlayer insulating films. Each shield layer is electrically connected to the fixed-potential side electrode of the storage capacitor, and each pixel electrode is disposed at an upper-layer side of the shield layer, is formed using a plurality of interlayer insulating films as an underlying layer, and is electrically connected to a pixel-potential side electrode of the storage capacitor through a pixel-electrode contact hole integrally penetrating the plurality of interlayer insulating films.
