Abstract
An active matrix board comprising pixel electrodes arranged in a matrix fashion on an insulating substrate, and scan lines each having an addition capacity electrode placed in a superposed relation with a portion of a corresponding one of the pixel electrodes, said scan lines each comprising a first scan line formed in an area other than the area in which said addition capacity electrode is held in a superposed relation with said pixel electrode, and a second scan line formed to cover said first scan line and having said addition capacity electrode as its part, whereby the possibility of pixel defect occurrence is reduced and the production yield of display apparatuses is improved.
