Abstract
In a thin-film-transistor-array substrate, a plurality of gate wires and a plurality of source wires are provided on the substrate to form a matrix; a pixel is formed on each of a plurality of areas each enclosed by two adjacent ones of the gate wires and two adjacent ones of the source wires; the pixel includes a thin-film-transistor having: a gate electrode formed as a portion of the gate wire; a source electrode formed as a portion of the source wire; and a drain electrode connected to a pixel electrode formed on an insulation layer covering the gate electrode, the gate wire, the source electrode and the source wire through a contact hole formed by boring the insulation layer, and a dummy hole is formed by boring a portion of the insulation film above at least one of the gate electrode, the gate wire, the source electrode and the source wire in close proximity to the contact hole with the dummy hole reaching the gate electrode, the gate wire, the source electrode or the source wire respectively.
