Abstract
The direct patterning method includes: providing a substrate having a display area and a peripheral area, which a peripheral circuit having a bonding pad is disposed on the peripheral area; sequentially disposing a metal nanowire layer, a pre-cured film layer and a negative-type photosensitive layer thereon; performing a photolithography step; and curing the pre-cured film layer. The photolithography step includes exposing the negative-type photosensitive layer to define a removal region and a reserved region; and removing the negative-type photosensitive layer, the pre-cured film layer and the metal nanowire layer in the removal region by using a developer, such that a touch sensing electrode is fabricated in the display area and the bonding pad is exposed.
