Abstract
A method of manufacturing an active panel results in a gate pad being formed so as to prevent being damaged by a probe pin during an auto probe testing process. An active panel made by the method includes a pad including a first conductive material an insulating layer on the pad, at least one contact hole exposing a portion of the pad, the insulating Layer covering a middle portion of the pad and a pad terminal connected to the pad through the at least one contact hole.
Claims27
A method of manufacturing a liquid crystal display, comprising:
- forming gate pads on a substrate using a first conductive metal;
- forming an insulating layer coveting the gate pads;
- forming a passivation layer on the insulating layer;
- and
- forming an array of buffer layer, each buffer layer covering only a middle portion of each gate pad by patterning the passivation layer and the insulating layer such that opposite ends of each gate pad are not covered by the buffer layer,
- wherein the array of buffer layers is formed and arranged to have a zig-zag pattern.
3 more elements
A method of manufacturing a liquid crystal display, comprising:
- forming a gate pad on a substrate using a conductive metal;
- and
- forming a buffer layer covering a middle portion of the gate pad, wherein a width of the buffer layer is about ¼ of a length of the buffer layer.
