Abstract
The invention provides a metal oxide in-plane switching liquid crystal display panel and a manufacturing method thereof. The metal oxide in-plane switching liquid crystal display panel comprises a scanning line, a signal line, pixel units, a common electrode line and a grid-shaped common electrode, wherein the signal line and the scanning line are crossed; the pixel units are subjected to crossed limitation of the scanning line and the signal line, and each pixel unit comprises a thin film transistor and a grid-shaped pixel electrode. Each thin film transistor comprises a thin film transistor (TFT) grid electrode electrically connected with the scanning line, a TFT source electrode electrically connected with a signal line connecting line, a TFT drain electrode electrically connected with the pixel electrode and a TFT channel region located between the TFT source electrode and the TFT drain electrode and positioned on a bottom layer. The common electrode line is parallel to the scanning line, the grid-shaped common electrode is electrically connected with the common electrode line, and the grid-shaped common electrode and the grid-shaped pixel electrodes are crossed in a pixel region. A metal oxide serves as a TFT channel semiconductor, the source electrode, the drain electrode, the grid-shaped pixel electrode or the grid-shaped common electrode to be used, the TFT driving capability can be improved, and a process can be simplified.
Description
technical field [0001] The invention relates to a metal oxide planar switch liquid crystal display panel and a manufacturing method thereof. Background technique [0002] Traditional CRT monitors rely on cathode ray tubes to emit electrons and strike phosphors on the screen to display images, but liquid crystal displays work on a completely different principle. Generally, a liquid crystal display (LCD) device has an upper substrate and a lower substrate spaced apart from each other and facing each other. A plurality of electrodes formed on the two substrates face each other. The liquid crystal is sandwiched between the upper and lower substrates. A voltage is applied to the liquid crystal through the electrodes on the substrate, and then the alignment of the liquid crystal molecules is changed according to the applied voltage to display images. Because the liquid crystal display device does not emit light as mentioned above, it needs a light source to display images. Ther...
