Abstract
A display apparatus includes scanning lines; signal lines crossing the scanning lines; thin-film transistors connected to the scanning lines and the signal lines; capacitors connected to the thin-film transistors; interlayer insulating films disposed over the scanning lines with the signal lines, the thin-film transistors, and the capacitors disposed between or on the interlayer insulating films; upper interlayer insulating films disposed above the signal lines, the thin-film transistors, and the capacitors; common lines disposed between or on the upper interlayer insulating films; pixel electrodes disposed between or on the upper interlayer insulating films; and connection holes continuously penetrating the interlayer insulating films disposed between the common lines and the capacitors. The common lines and the capacitors are directly connected via the connection holes, and the connection holes have a ratio of depth to opening width of more than 1.
