The invention is directed to narrowing a frame of a liquid crystal display device including a display pixel region and a dummy pixel region adjacent thereto. The display pixel region including a plurality of pixels each having a pixel selection TFT and a pixel electrode connected thereto is formed on a first substrate. The dummy pixel region including a plurality of dummy pixels each having a pixel selection TFT and a pixel electrode connected thereto and shielded from light by a black matrix is formed adjacent to the display pixel region. A driving TFT, that is, a sampling TFT is further formed being superposed on the pixel electrode of the dummy pixel. That is, the pixel electrode of the dummy pixel is superposed on at least a portion of a channel region of the sampling TFT with a planarization insulation film interposed therebetween.
