Abstract
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.
