Abstract
The present invention discloses a liquid crystal panel, liquid crystal display device and manufacturing method of array substrate thereof. The liquid crystal panel comprises: a color filter substrate and an array substrate, disposed with spacing, surface of array substrate facing color filter substrate being disposed with a plurality of pixel units, each of pixel units comprising a thin film transistor, a pixel electrode and a VIA connecting thin film transistor and pixel electrode; at least an auxiliary hole formed by same EPD etching as VIA being disposed between pixel units or in each pixel unit. The present invention can amplify the detection voltage, which enables monitoring VIA forming process more precisely and reliably to ensure the VIA manufacture quality.
