Publication number: 20180052347Abstract: The present invention provides a VA type COA liquid crystal display panel, and the first light shielding layer having red or blue color resist material and the common electrode above the first light shielding layer are correspondingly located above the gate scan line, and the common electrode is electrically coupled to the common electrode layer on the upper substrate, and thus, the voltage difference of the upper, lower substrates is 0 at the gate scan line. Moreover, the panel appears an often black state at the gate scan line because the liquid crystal is not driven by the voltage; besides, the second light shielding layer formed by stacking up two of the red, the green and the blue color resist materials is correspondingly located above the data line; accordingly, the black matrix is eliminated, and the panel aperture ratio is high.Type: ApplicationFiled: February 26, 2016Publication date: February 22, 2018Inventor: Chengzhong Yu
