Tft and lcd panel and method for manufacturing the same

A method of forming a liquid crystal display panel, characterized in that:

• a glass substrate is provided;
• a first metal layer formed on the glass substrate is etched to form a control electrode of a switch unit;
• a first passivation layer and a second metal layer are deposited on the glass substrate and on the first metal layer in order;
• the second metal layer is etched to form a data line;
• an isolation layer and an active layer are deposited on the first passivation layer and on the second metal layer in order;
• the active layer is etched simultaneously for reserving the active layer above the control electrode, and the active layer serves as a channel of the switch unit;
• the first passivation layer and the isolation layer above the data line are etched to form a via hole on top of the data line;
• a transparent conducting layer is deposited on the isolation layer, the data line, and the active layer;
• and
• the transparent conducting layer is etched to divide the transparent conducting layer into a first transparent conducting layer and a second transparent conducting layer, wherein the data line is electrically connected to the active layer through the first transparent conducting layer on the via hole, and the active layer is electrically connected to the second transparent conducting layer.
