Claim Text:
1. A method of forming a liquid crystal display panel, characterized in that the method comprises: providing a glass substrate; etching a first metal layer formed on the glass substrate to form a data line; depositing a first passivation layer and a second metal layer on the glass substrate and on the first metal layer in order, the first passivation layer being connected to the glass substrate and to the first metal layer; etching the second metal layer to form a gate of a thin film transistor and a bottom electrode of a storage capacitor; depositing an isolation layer and an active layer on the first passivation layer and on the second metal layer in order; etching the active layer for reserving the active layer above the control electrode, and the active layer being used as a channel of the thin film transistor; etching the first passivation layer and the isolation layer above the data line to form a via hole on top of the data line; depositing a transparent conducting layer on the isolation layer, the data line, and the active layer; disposing an ohmic contact layer between the active layer and the transparent conducting layer; and etching the transparent conducting layer to divide the transparent conducting layer into a first electrode and a second electrode, wherein the data line is electrically connected to the active layer through the first electrode on the via hole, and the active layer is electrically connected to the second electrode.
