Abstract

An In Plane Switching (IPS) liquid crystal displaying apparatus includes a TFT array substrate, an opposite substrate opposed to the TFT array substrate and a liquid crystal interposed between the TFT array substrate and the opposite substrate. The TFT array substrate includes a plurality of driving electrodes formed on a passivation film and connected with the plurality of TFTs, a plurality of opposite electrodes formed on the passivation film, each of the plurality of opposite electrodes opposing the respective plurality of driving electrodes, and a plurality of common lines configured to connect each of the plurality of opposite electrodes with each of a plurality of pixels. The TFT array substrate provided with a light shielding formed in such a manner as to superpose one signal line of the plurality of signal lines and one opposite electrode of the plurality of opposite electrodes.
