ABSTRACT:
A COG type liquid crystal display panel10in which a rectangular chip mounting area MA for mounting an IC chip14is provided on one of a pair of substrates11, 12on which a plurality of electrodes are provided, a plurality of extraction electrodes20that are severally connected to the electrodes are lead out into the chip mounting area, and the terminals for bump21uto21z, 31uto31zconnected to bump terminals of the IC chip are formed on the extraction electrodes, from which the extraction electrodes are lead out at least on two sides of the rectangular chip mounting area and further extended into the chip mounting area from the terminals for bump and terminals for inspection22uto22z, 32uto32zare arrayed on extended end portions of the extraction electrodes so as to be drawn up in a line according to a predetermined rule of the electrodes to which the extraction electrodes are connected. Consequently, it is possible to provide a liquid crystal display panel upon which intermediate functional inspection can be easily performed even if it is a COG type liquid crystal display panel on which a fairly large number of extraction electrodes exist.
