Array substrate for a liquid crystal display device and method of manufacturing the same
First Claim
Patent Images
1. A manufacturing method of an array substrate for a liquid crystal display device, comprising:
- forming a gate line on a substrate;
forming a data line crossing over the gate line;
forming an independent portion under the data line at a crossing point of the gate and data lines, wherein the independent portion is separated from the gate line is formed of the same layer as the gate line, and is inside the gate line;
forming a thin film transistor near the crossing point of the gate and data lines and connected to the gate and data lines; and
forming a pixel electrode connected to the thin film transistor.

Abstract
An array substrate for a liquid crystal display device includes a substrate, a gate line elongated in one direction, a data line crossing over the gate line, a thin film transistor near a crossing point of the gate and data lines and connected to the gate and data lines, an independent portion under the data line at the crossing point, the portion being separated from the gate line, and a pixel electrode connected to the thin film transistor. The independent portion may be inside the gate line.
The parasitic capacitor between the gate line and the data line can be reduced. And amount of light from the backlight device can be reduced.
