Abstract
A direct patterning method of touch panel is provided. A substrate having a display region and a peripheral region is provided. A periphery circuit having a bonding pad is disposed on the periphery region. A metal nanowire layer made of metal nanowires are disposed on the display region and the peripheral region. A photosensitive pre-cured layer is disposed on the metal nanowire layer. A photolithography process is performed, which includes exposing the pre-cured layer to define a removal area and a reserved area, and removing the pre-cured layer and the metal nanowire layer on the removal area using a developer solution to form a touch-sensing electrode disposed on the display region and to expose the bonding pad disposed on the periphery region. The touch sensing electrode made of the pre-cured layer and the metal nanowire layer is electrically connected to the periphery circuit.
