摘要： A display device according to the present invention includes a liquid crystal display panel in which a plurality of pixels are arranged in matrix, and an optical sensor circuit configured by a photodiode (17), a NetA voltage-boosting capacitor, and an output AMP. A driving wiring (Vrwn) for supplying a driving signal to the NetA voltage-boosting capacitor is electrically connected to a power supply wiring (Vsm) for supplying power to the output AMP. This configuration reduces parasitic capacitance resulting from an increase in the number of wirings. This makes it possible to make a display device having a pixel including an optical sensor incorporated therein, the display device capable of avoiding deterioration in sensor accuracy in the optical sensor circuit and preventing a decrease in the aperture ratio of the pixel.

摘要： An protective film and a resin layer are stacked on an insulation substrate on which a TFT is formed, and after a contact hole is formed in the resin layer, the protective film below the contact hole is etched and removed. A pixel display electrode is allowed to contact a drain electrode at the area of the contact hole; thus, a liquid crystal display is formed. A cut-out section, which communicates with the lower layer is formed in the drain electrode in the area of the contact hole. Upon forming a TFT section island-shape semiconductor layer so as to provide a TFT, a hole section island-shape semiconductor layer is also formed in the area of the contact hole. With this arrangement, it is possible to provide a manufacturing method of a liquid crystal display which can avoid the occurrence of a step discontinuity in the pixel display electrode and the subsequent disconnection in the pixel display electrode.
