Abstract:
A display device comprising:a first substrate; a second substrate, which is disposed so as to face the first substrate; and a display medium layer, which is provided between the first and second substrates, wherein the first substrate includes: a plurality of striped data electrodes, each of which has a first end and a second end and which extends in a column direction; a first group of connecting pads, each of which is electrically connected to the first end of associated one of the data electrodes; and a second group of connecting pads, each of which is electrically connected to the second end of associated one of the data electrodes, and wherein the second substrate includes: a plurality of gate lines and a plurality of reference signal lines, each of the gate lines and each of the reference signal lines extending in a row direction; a plurality of pixel electrodes, which are arranged in matrix; a plurality of switching elements, each of which has its ON/OFF states controlled by a voltage applied through associated one of the gate lines and is provided between associated one of the reference signal lines and associated one of the pixel electrodes; a plurality of data signal input terminals, each of which receives a data signal to be supplied to associated one of the data electrodes; a spare line, which is used to pass the data signal to be supplied to one of the data electrodes; a third group of connecting pads, which is electrically connected to the data signal input terminals and which is provided so as to face the first group of connecting pads; and a fourth group of connecting pads, which is provided so as to face the second group of connecting pads and which crosses the spare line with an insulating layer interposed between the fourth group of connecting pads and the spare line, and wherein each of the connecting pads in the third group is electrically connected to associated one of the connecting pads in the first group with an anisotropic conductive material, and wherein each of the connecting pads in the fourth group is electrically connected to associated one of the connecting pads in the second group with the anisotropic conductive material.
