Patent ID: 8289491

Claim:
A liquid crystal display device, comprising: a p-type driving thin film transistor and an n-type driving thin film transistor in a non-display region of a substrate, the p-type driving thin film transistor including a first polycrystalline semiconductor pattern, a first gate electrode, a first source electrode and a first drain electrode, and the n-type driving thin film transistor including a second polycrystalline semiconductor pattern, a second gate electrode, a second source electrode and a second drain electrode, wherein each of the first source electrode, the first drain electrode, the second source electrode and the second drain electrode has a top surface and a side surface; a gate line and a data line in a display region of the substrate and that cross each other to define a pixel region, wherein the data line has a top surface and a side surface; a pixel thin film transistor connected to the gate line and the data line, the pixel thin film transistor including a third polycrystalline semiconductor pattern, a third gate electrode, a third source electrode and a third drain electrode, wherein the third source electrode has a top surface and a side surface; a pixel electrode that covers and directly contacts the third drain electrode; a shield pattern that covers and directly contacts the top surfaces of each of the first source electrode, the first drain electrode, the second source electrode and the second drain electrode, and covers and directly contacts the side surfaces of each of the first source electrode, the first drain electrode, the second source electrode and the second drain electrode; and a shield line that covers and directly contacts the top surfaces of each of the data line and the third source electrode, and covers and directly contacts the side surfaces of each of the data line and the third source electrode, wherein the pixel electrode, the shield pattern and the shield line are made of a transparent conductive material.
