Abstract: Semiconductor quantum dots（QDs）have unique optical properties，so they have very high application value in displaying material domain. Comparing with traditional displaying materials，QDs optical devices have the advantages such as brightness，color purity and energy efficiency，which make them the ideal displaying materials. Based on the current works，introduces the optical principles，optical properties and common synthesis methods of QDs，also introduces the developments and challenges of QDs， and outlook the application of the QDs on flexible displayer.

Key words: quantum dots（QDs）, display materials, flexible displayer, nanomaterial, fluorescent
