A conductive pattern forming method according to an embodiment includes: forming a first conductive pattern on a substrate; sequentially forming a release layer and a conductive layer on a transfer substrate that includes a mask; irradiating intense pulsed light (IPL) to the substrate where the first conductive pattern is formed; placing the transfer substrate on the substrate; transferring a portion of the conductive layer, corresponding to an opening of the mask, onto the substrate by irradiating the IPL to the transfer substrate to form a second conductive pattern on the substrate.
