Abstract:
1. A method for manufacturing a display device, the method comprising: forming a microwell including a lower wall and one or more peripheral side walls extending upward from the bottom wall, wherein an upper edge of the peripheral cell wall defines an opening; inserting an ink solution into the microwell structure through the opening, wherein the ink solution includes particles and one of an isoparaffinic-based suspension fluid and an oil-based suspension fluid; overcoating the microwell with a sealing solution including a polymer suspended in one of an aqueous solution and a hydroalcoholic solution; and curing the sealing solution such that the polymer forms a membrane that adheres to the upper edge of peripheral side wall and covers the opening, thereby sealing the ink solution inside the microwell, wherein the sealing solution comprises one of an alkylester of PVM/MA copolymer and PVA/VA.
