Powder electroluminescent devices (PELDs) have high potential of commercial applications because of their flat light emission and printing processes. In this study, we develop PELDs on gravure offset printed invisible Ag-grid laminated with PEDOT:PSS transparent electrodes. The PELDs with the invisible Ag-grid transparent electrodes showed excellent electroluminescent properties.
