Array, substrate, and display device and its manufacturing method

A method for fabricating a plurality of display devices comprising the steps of:

• preparing an array substrate having on an insulative substrate:
• a plurality of display areas to be portions of a plurality of display panels, each display area being constituted with a plurality of pixels arranged in a matrix, the pixels having pixel electrodes formed at intersection portions of plural scan wirings and plural signal wirings;
• a common wiring formed outside each display area for applying a reference voltage to the pixels;
• and a plurality of external-connection terminals formed outside each display area, to be connected with a driver circuit that drives the display panel;
• the array substrate comprising 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;
• bonding the array substrate together with an opposite substrate with a gap therebetween;
• and
• cutting the bonded array substrate and opposite substrate along the cutting line to separate the bonded substrates individually for the respective display areas, to provide a plurality of display panels.
