Abstract
In one aspect of the invention, the method of forming a TFT array panel includes forming a patterned first conductive layer on a substrate, forming a gate insulating layer on the patterned first conductive layer and the substrate, forming a patterned semiconductor layer on the gate insulating layer, forming a patterned second conductive layer, forming a patterned passivation layer on the patterned second conductive layer and the substrate, and forming a patterned transparent conductive layer on the patterned passivation layer.
Claims14
A method of forming a thin film transistor (TFT) array panel, comprising:
- (i) forming a patterned first conductive layer, including a gate line and a shielding portion, on a substrate, the shielding portion being electrically floated;
- (ii) forming a gate insulating layer on the patterned first conductive layer and the substrate;
- (iii) forming a patterned semiconductor layer, including a portion that overlaps the shielding portion, on the gate insulating layer;
- (iv) forming a patterned second conductive layer, including a source electrode and a drain electrode on the patterned semiconductor layer, and a data line electrically connected to the source electrode, wherein the shielding portion is not overlapped with the data line;
- (v) forming a patterned passivation layer on the patterned second conductive layer and the substrate;
- and
- (vi) forming a patterned transparent conductive layer on the patterned passivation layer.
