A method of forming an insulating layer and a touchscreen including the insulating layer formed using the same are provided. The method of forming an insulating layer insulating a conductive pattern of a touchscreen from a bridge electrode thereof includes heating a substrate provided with the conductive pattern formed on the substrate, sequentially forming a first pattern and a second pattern on the heated substrate using an insulating composition, and curing the first pattern and the second pattern. The first pattern includes a groove portion to prevent adjacent patterns from overlapping each other and the second pattern is formed in the groove portion of the first pattern.
