LIQUID CRYSTAL DISPLAY DEVICE

摘要

An object of the present technology is to provide an input device as a capacitance coupling type input device capable of easily being incorporated into a display device. A liquid crystal display device of the present technology includes: a liquid crystal panel 1 having a plurality of pixel electrodes 19 and a common electrode provided so as to be opposed to the pixel electrodes 19, and updating a display by sequentially applying a scanning signal to TFTs that control application of a voltage to the pixel electrodes 19; and an input device having a plurality of driving electrodes 11, which are formed by dividing the common electrode of the liquid crystal panel 1 by providing a slit 25, and a plurality of detection electrodes 12 arranged so as to cross the driving electrodes 11, and capacitive elements formed between the driving electrodes 11 and the detection electrodes 12. A shielding electrode 26 is arranged at a position corresponding to the slit 25 in the periphery of the pixel electrodes 19.
