  • Active matrix substrate and method of manufacturing the same
    Patent number: 7476899
    Abstract: Extraction wirings are respectively connected to a signal line of a switching element and a scanning line thereof, and led out to one side portion of a transparent insulating substrate. Conductive terminals respectively united with the extraction wiring are formed in tip end portions thereof, and a plurality of contact holes connected to the conductive terminals are formed on the conductive terminals so that a diver IC is mounted thereon by using conductive resin. Each of the extraction wirings is provided with a semiconductor film pattern in the vicinity of the contact hole for blocking the moisture in the conductive resin to reach the extraction wirings through an interlayer insulating film.
    Type: Grant
