THIN FILM TRANSISTOR SUBSTRATE OF LIQUID CRYSTAL DISPLAY AND METHOD FOR FABRICATING THE SAME

摘要

PURPOSE: A thin film transistor substrate of a liquid crystal display and a method for fabricating the substrate are provided to secure adhesive strength between a pad and an output terminal of a tap driving IC. CONSTITUTION: A thin film transistor substrate of a liquid crystal display includes an insulating substrate(10), a gate line formed on the substrate, a gate insulating layer(60) covering the gate line, a semiconductor pattern(70) formed on the gate insulating layer, and a data line formed on the semiconductor pattern or the gate insulating layer. The gate line includes a gate electrode(56) and a gate pad(53), and the data line includes source and drain electrodes(95,96) and a data pad(98). The thin film transistor substrate further has a passivation film(100) and a pixel electrode(112). The passivation film covers the data line and the semiconductor pattern and has the first contact hole(102) exposing the drain electrode and the second contact hole(108) exposing the gate pad or the data pad. The pixel electrode is connected to the drain electrode through the first contact hole.
