Abstract
A liquid crystal display device having first and second substrates with a liquid crystal layer therebetween, a plurality of scanning signal lines and a plurality of video signal lines formed on the first substrate, and a plurality of thin film transistors formed proximate to a crossing point of the scanning signal lines and video signal lines. A light shielding layer is formed on the second substrate and overlapped with at least one of the thin film transistors and with at least one signal line of the scanning signal lines and the video signal lines in plane view. The light shielding layer has an aperture region which is formed proximate to the at least one thin film transistor and formed within the at least one signal line in plane view.
