Abstract
Light-emitting film having low or no degradation of light emission characteristics at film side surfaces, methods of making, and displays and electronic devices such as electronic readers formed with the light-emitting film. In one instance, the light-emitting film contains quantum dots in a polymeric matrix, has side surfaces protected with one or more oxygen and moisture barrier layers, and may be formed using transfer molding.
