An array substrate comprises on an insulative substrate, a plurality of display areas to be portions of a plurality of display panels, in which, each display area is constituted with a plurality of pixels arranged in a matrix, and the pixels is constituted with pixel electrodes formed at intersection portions of plural scan wirings and plural
signal wirings; a common wiring is formed outside each display area, for applying a reference
voltage to the pixels; a plurality of external-connection terminals is formed outside each display area, to be connected with a
driver circuit that drives; and comprises connection wirings located so as to intersect a
cutting line along which the insulative substrate is to be
cut, for connecting the external-connection terminals in one of the display panels on the insulative substrate with a common wiring in another one of the display panels adjacent to the external-connection terminals, wherein the connection wirings are formed in a conductive layer superior in
corrosion resistance to the most inferior
corrosion-resistance conductive layer among conductive
layers constituting the array substrate.
