The present invention discloses a liquid crystal display (LCD) panel and method for forming the same. In the LCD panel, the TFT includes a source and a drain formed by a transparent conducting layer, and a gate formed by a metal layer. The source is electrically connected with a data line through a via hole over the data line. The source connects to the drain via an active layer. Whatever the number of data lines are, each pixel corresponds to an associated via hole, so the number of via holes does not increase, and not reduce the aperture ratio. Therefore, the present invention is very proper to a design using more data lines and working in a high frequency. Moreover, the matrix circuitry of LCD of the present invention is well applied in a display which not only increases a density of data lines to raise the frame rate, but also maintains the aperture ratio and brightness.

A thin film transistor (TFT) liquid crystal display (LCD) comprises a plurality of image pixels demarcated between an overlying liquid crystal display layer and an underlying glass substrate. Each image pixel comprises a dedicated top-gate TFT disposed over the glass substrate. Each top-gate thin film transistor comprises a process sensitive semiconductor layer disposed over the glass substrate, and a source electrode and a drain electrode disposed over the process sensitive semiconductor layer. The process sensitive semiconductor layer forms a process sensitive semiconductor active layer between the source electrode and the drain electrode and an active layer protection film is disposed over the process sensitive semiconductor active layer. A gate dielectric layer is disposed over the active layer protection film between the source electrode and the drain electrode and a gate electrode is disposed over the gate dielectric layer.
