Abstract

The object of the present invention is to provide a TFT array for obtaining a liquid crystal display apparatus of large screen size, of high aperture ratio, and of high precision without degrading the display quality through cross talks or shot blurs. The TFT array of the present invention is a TFT array substrate comprising: a transparent insulating substrate; a plurality of parallel gate electrode lines; a plurality of parallel source electrode lines crossing to the gate electrode lines; a plurality of TFTs located on each crossing point of the gate electrode lines and the source electrode lines; a passivation film formed on the TFTs; a plurality of transparent pixel electrodes formed on said passivation film corresponding to each said TFT and connected to a drain electrode of each said TFT via contact hole; a plurality of floating electrodes which serve as light shielding layer made of a same layer as that of said gate electrode lines formed in a peripheral portion of each said pixel electrode.
