NOVELTY - Preparing graphene oxide optical cell involves applying predetermined shearing force to graphene oxide to form a uniform pattern optical cell. USE - Method for preparing graphene oxide optical cell (claimed). ADVANTAGE - The method enables to prepare graphene oxide optical cell that is capable of the uniform color reflection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene oxide optical cell, which involves: (A) preparing an upper substrate, lower substrate and gap portion having an open upper portion and a space into which the graphene oxide cell can be inserted; (B) disposing the lower substrate and the gap portion on the lower substrate; (C) injecting the graphene oxide cell into the gap portion; and (D) disposing the upper substrate on the graphene oxide cell, and pushing the graphene oxide cell in a predetermined direction using the upper substrate.
