Application of a ZnO nanorod layer to display retarder: dependence of the optical property on synthesis conditions

Abstract

A series of zinc oxide nanorods (ZnO NRs) were grown by chemical bath deposition and their optical properties as a retarder for display devices were investigated. The effect of the precursors, growth time, and calcination time on the morphology and the optical properties was examined. The vertically-grown ZnO NRs layer represented positive c-plate property. We simulated the antireflection property of a quasi-circular polarizer containing the ZnO NRs layer for an organic light emitting diode (OLED) display. The quasi-circular polarizer with the ZnO NRs layer showed better antireflection property than the polarizer containing no ZnO NRs layer.
