Abstract
Official abstract text for this publication.
An object of the present technology is to provide a display device that includes an input device capable of easily being incorporated into the display device as a capacitance coupling type input device. The display device includes: a display panel having a plurality of pixel electrodes 19 and updating a display by sequentially applying a scanning signal to a TFT that controls application of a voltage to the pixel electrodes 19 ; and an input device having one of electrodes arranged in the periphery of the pixel electrode 19 of the display panel and the other electrode arranged so as to cross the one of electrodes, wherein a capacitive element is formed between the one of electrodes and the other electrode. The one of electrodes arranged in the periphery of the pixel electrode 19 is composed of a lower layer portion 27 a made of a metallic material, and an upper layer portion 27 b covering the lower layer portion 27 a and made of the same material as the pixel electrode 19.
First claim
