Abstract: The present invention provides a TFT array substrate and a manufacturing method thereof. The TFT array substrate has a source electrode (801) and a drain electrode (802), which each include, stacked from bottom to top, a first molybdenum layer (811), a first aluminum layer (812), a second aluminum layer (813), and a second molybdenum layer (814). The first aluminum layer (812) and the second aluminum layer (813) each have a surface including a plurality of spikes (8120) formed and distributed thereon. The spikes (8120) of the second aluminum layer (813) have a height greater than a height of the spikes (8120) of the first aluminum layer (812) such that the source electrode (801) and the drain electrode (802) each have an upper surface exhibiting a rough surface having irregularity comprising raised and recessed portion. Compared to a flat smooth surface that is involved in the prior art, the rough surface having irregularity comprising raised and recessed portions helps expand contact area between the drain electrode (802) and the pixel electrode (1200) so as to reduce contact impedance between a TFT and the pixel electrode and improve performance of a liquid crystal display panel.

Abstract: The present application provides a method of fabricating a COA type liquid crystal display panel and the COA type liquid crystal display panel, which utilizes reactive liquid crystal, reactive monomers, red quantum-rods and green quantum-rods to fabricate a color filter thin film. Due that light generated by the red and green quantum rods in the color filter thin film when they are excited are polarized light, and the red and green quantum rods therein are arranged along the same direction, the excited red and green quantum rods generate red and green linear polarized light conforming to the polarized direction so as to play a role of a lower polarizer and to allow the COA type liquid crystal display panel fabricated by the method not only obtain bright trichromatic light for increasing color saturation, but also omit the lower polarizer for reducing fabrication cost.

Abstract: The present invention provides a display panel and a manufacture method thereof. By locating the matrix electrode corresponding to the black matrix on one side of the color film substrate, which is close to the liquid crystal layer, and because the matrix electrode is coupled to the common electrode signal, no voltage difference exists between the matrix electrode and the common electrode, and no matter in condition of being electrified or not electrified, the liquid crystal layer between the matrix electrode and the common electrode of the array substrate is not orientated and constantly appears in an opaque state so that no interference generates to light between adjacent pixels of the panel to eliminate the large view angle color washout of the panel and to improve the display quality of the LTPS display panel.
