  • Patent number: 10025129
    Abstract: The present disclosure relates to an array substrate and a touch panel. The array substrate includes a pixel electrode layer, a first touch electrode layer and an insulation layer and a second touch electrode layer arranged on the first touch electrode layer in sequence. The pixel electrode layer is not overlapped with at least one of the first touch electrode layer and the second touch electrode layer, and the insulation layer is not provided within a vertical projection area of the pixel electrode layer. In this way, when the thickness of the insulation layer between the first touch electrode layer and the second touch electrode layer is increased to reduce the parasitic capacitance between the touch electrode layers, the dimension of the liquid crystal capacitor and the storage capacitor is prevented from being affected.

    Abstract: An electro-optical device is capable of high quality images. An electro-optical device (200) includes a first capacitive element (491), a second capacitive element (492), and a third capacitive element (493). The first capacitive element (491) includes a first conductive film (408), a first part of a second conductive film (411), and a first dielectric film (410). The second capacitive element (492) includes a third conductive film (416), a second part of a fourth conductive film (418), and a second dielectric film (417). The third capacitive element (493) includes the third conductive film (416), a third part of the fourth conductive film (418), and the second dielectric film (417). Since a capacitive element that includes a large capacitance value is formed in a narrow region, even if the pixel becomes smaller as the definition is increased, it is possible to realize an excellent electro-optical device in which display defects are suppressed.
