Kind Code:
A1
Abstract:
[Problem] To provide a production method for a display device having excellent display properties and wherein no electrode corrosion occurs due to a battery reaction, and, to provide a display device and electronic equipment. [Solution] The production method for the display device according to an aspect of the present technique comprises steps of: forming, in a display region on a base board, a first electrode having a first conductive material; forming, in an outer region of the display region on the base board, a second electrode electrically connected to the first electrode and having a second conductive material different from the first conductive material; forming an interlayer insulation film so as to cover the first electrode and the second electrode; forming in the interlayer insulation film a plurality of first open portions to expose at least a portion of the first electrode; forming in the interlayer insulation film a plurality of second open portions to expose at least a portion of the second electrode; forming above the exposed second electrode an anisotropic conductive layer; and, after forming the anisotropic conductive layer, exposing the first open portions, the second open portions, and the interlayer insulation film, to a liquid containing an electrolyte.
