Patent ID: 7245012

Claim:
A thin film transistor (TFT) substrate comprising: a glass substrate; a thin film transistor formed on the glass substrate; an electrode pad formed on the glass substrate and electrically connected with the thin film transistor; and a conductive bump comprising: a plurality of insulating bumps formed on the electrode pad dividedly and in direct and full contact with the electrode pad, wherein the plurality of insulating bumps comprises four insulating bumps arranged as a matrix; a conductive layer, covering the upper surfaces of the insulating bumps, the inward surfaces of the insulating bumps, and part of the electrode pad between the insulating bumps, and electrically connected with the electrode pad, wherein the outward side surfaces of the insulating bumps are exposed out of the conductive layer; wherein a gap exists between the conductive layer covering the inward surfaces of the insulating bumps.
