Abstract

An LTPS array substrate includes a plurality of LTPS thin-film transistors and a bottom transparent conductive layer, a protective layer, and a top transparent conductive layer. Each LTPS thin-film transistor includes a substrate, a patternized light shield layer, a buffering layer, a patternized poly-silicon layer, a gate insulation layer, a gate line, and a common electrode line, an insulation layer, a drain and a source, and a planarization layer that are formed to sequentially stack on each other. The light shield layer covers the scan line and the source/drain. A patternized third metal layer is between the bottom transparent conductive layer and the protective layer and includes a first zone and a second zone intersecting the first zone. The first zone shields the source line. A portion of the second zone overlaps a side portion of the light shield layer that is close to the source/drain electrode.
