Abstract

In order to improve the picture quality, such as by minimizing the smear in a liquid crystal display device of the in-plane field type having a wide viewing field, and to reduce power consumption, in the active-matrix liquid crystal display device, over the transparent substrate opposed to the transparent substrate over which the video signal lines are provided, a shield electrode is formed completely overlapping the video signal lines in plan view, the light shielding layer has a multilayer structure comprising CrO and Cr layers in this order from the transparent substrate side to the liquid crystal layer side, a connection terminal for supplying a reference signal to the light shielding layer is formed over the transparent substrate over which the display electrodes, the scan signal lines, the video signal lines and the active devices are provided, and a conductive layer to electrically connect the light shielding layer and the connection terminal is provided.
