An interlayer insulating film is provided on the switching element. A pixel electrode connected with the switching element is provided on the interlayer insulating film. Moreover, a spacer for keeping a thickness of a liquid crystal layer constant is disposed in the liquid crystal layer and in a sealing member for sealing the liquid crystal layer. Materials of the interlayer insulating film and spacers are optimized. This configuration prevents degradation of a defective ratio and reliability due to the spacer disposed in the liquid crystal layer sinking into the interlayer insulating film.

摘要： A gate insulating film, a lower-layer pixel electrode, an inter-layer insulating film, and an upper-layer pixel electrode, in that order, are provided on a transparent insulating substrate. The lower-layer pixel electrode and the upper-layer pixel electrode are connected to the drain electrode of a TFT, and a plurality of holes are provided in the upper-layer pixel electrode. Where the upper-layer pixel electrode lies, the image signal voltage is applied directly to the liquid crystal, but where there are holes in the upper-layer pixel electrode, a divided capacitance voltage of the serial capacitances of the liquid crystal and the inter-layer insulating film is applied. In this way, it becomes possible to effectively form within the same pixel several domains with different viewing angle characteristics, without giving rise to disturbance of alignment.

摘要： On an active matrix substrate having a TFT in the vicinity of the intersection of a gate line and a source line and a pixel electrode connected to the TFT, an inter-layer insulating film is formed by an acrylic resin, for example, between the pixel electrode and the gate line, source line and TFT. The pixel electrode does not overlap a self gate line, but overlaps a gate line adjacent to the self gate line. At least one of the gate line and the source line has a redundant structure including ring-shaped sections connected in a longitudinal direction so as to provide redundancy as a measure to counter the disconnection of lines.
