In a liquid crystal display device comprising a first substrate 101 having a color filter, a second substrate 131 and a liquid crystal layer disposed therebetween, a color filter layer 110 is disposed on a protection film 108 of a thin film transistor formed on the first substrate 101 so as to be partitioned by a light shielding portion 111, and a common electrode 103 is disposed thereon. A pixel electrode to be connected to a source electrode 107 is disposed through a through hole formed in an overcoat layer (interlayer separation film) 112. On the first substrate below the color filter layer 110 are provided plural scan signal electrodes, plural video signal electrodes crossing the scan signal electrodes in a matrix form, plural thin film transistors formed in association with the crossing points between the electrodes. Each pixel is provided with a common electrode 103 which is connected over plural pixels through a common electrode wire to supply reference potential, and a pixel electrode 114 which is connected to the corresponding thin film transistor and disposed so as to confront the common electrode in the pixel area. |
