Abstract
An active-matrix addressing LCD panel is provided, in which a bypass can be readily formed for a broken one of the source/drain bus lines without degrading any display characteristic and without increasing the number of man-hour. A TFT-array substrate of the panel has gate bus lines and source/drain bus lines extending perpendicular to each other, pixel areas defined by the gate and source/drain bus lines, TFTs formed near respective intersections of the gate and source/drain bus lines in the corresponding pixel areas, pixel electrodes formed in the respective pixel areas, and light-shielding layers formed in the respective pixel areas. Each of the source/drain bus lines is overlapped with a corresponding one of the light-shielding layers at first and second locations. The first and second locations are defined in such a way that a bypass for each of the source/drain bus lines is formed by electrically connecting each of the source/drain bus lines to the corresponding one of the light-shielding layers at the associated first and second locations.
