Driving circuit for a liquid crystal display device, method of manufacturing the same and display device having the same

An LCD device comprising:

• a driving circuit comprising:
• an integrated circuit (IC) that generates a signal;
• an electrode pad formed on the IC to transmit the signal;
• a bump formed on the electrode pad to receive the signal;
• a conductive particle formed on the bump;
• and
• a conductive layer disposed between the bump and the conductive particle, wherein the conductive particle includes a first electrically conductive material, the conductive layer includes a second electrically conductive material and the conductive layer electrically connects the bump and the conductive particle;
• a thin-film transistor (TFT) array substrate comprising a pad electrically connected to the bump of the driving circuit through the conductive particle of the driving circuit;
• a color filter substrate facing the TFT array substrate;
• and
• a liquid crystal layer disposed between the TFT array substrate and the color filter substrate.
