Method for manufacturing light-transmissive substrate and light-transmissive substrate manufactured by using same

The present invention provides a method for manufacturing a light-transmissive substrate comprising a first transparent conductive layer, a second transparent conductive layer, and a base polymer layer, the method comprising: a first step of preparing a release layer; a (2-1) th step of forming the first transparent conductive layer on the release layer; a (2-2) th step of forming, on the first transparent conductive layer, the second transparent conductive layer including a conductor and a polymer cladding layer for covering the conductor; a third step of forming the base polymer layer on the second transparent conductive layer; and a fourth step of separating the release layer from the first transparent conductive layer so as to obtain the light-transmissive substrate comprising the first transparent conductive layer and the base polymer layer.
