Abstract
A liquid crystal display apparatus includes a transistor array substrate having formed thereon an array of pixel electrodes arranged in a matrix to form pixels, an array of switching thin film transistors arranged in a matrix for driving the pixels, respectively, gate bus lines arranged in rows for applying scanning signals to the switching thin film transistors, and source bus lines arranged in columns for applying display data signals to the switching thin film transistors. A counter substrate has formed thereon a common counter electrode confronting the pixel electrodes, and a liquid crystal layer is sandwiched between the transistor array substrate and the counter substrate. The transistor array substrate further has formed thereon a common electrode disposed below the pixel electrodes through an insulating layer for constituting auxiliary capacitors with the pixel electrodes. The common electrode is extended to cover an area above each source bus line or each gate bus line through another insulating layer so as to shield the pixel electrodes from the source or gate bus lines.
