Patent ID: 7733456

Claim:
A liquid crystal display device, comprising: a plurality of signal lines including a date line, a gate line and a common line on a substrate; a pixel electrode formed at an intersection area of the data line and the gate line; a plurality of pad electrodes including a gate pad electrode, a data pad electrode and a common pad electrode on the substrate, each one of the plurality of pad electrodes connected to one of the plurality of signal lines; two insulating films on the gate pad electrode and the common pad electrode, the two insulating films having a plurality of contact holes to expose a plurality of portions of each of the gate pad electrode and the common pad electrode; and anisotropic conductive film of which a plurality of conductive particles are directly connected to each of the gate pad electrode and the common pad electrode through the contact holes without any intermediate layer there-between covering the contact holes and the gate and common pad electrodes, wherein the pixel electrode and a common electrode is formed to generate a horizontal electric field in a pixel region defined by the intersection of the gate and data lines, wherein each of the plurality of the contact holes has a depth larger than diameter of the conductive particles of the anisotropic conductive film, wherein the data pad electrode include a semiconductor pattern having an active layer and an ohmic contact layer, wherein each of the plurality of contact holes has a first U-shaped contact hole and a second U-shaped contact hole engaged with the first U-shaped contact hole along a widthwise direction of the pad electrodes.
