Summary:To provide a display device including a quantum dot.SOLUTION: A display device includes a display region. The display region includes a light-emitting element in which a first electrode, a layer between the first electrode and a light-emitting layer, the light-emitting layer, a layer between the light-emitting layer and a second electrode, and the second electrode are stacked on the substrate in this order. The light-emitting layer is formed of an inorganic layer including a quantum dot. The light-emitting element is of a top-emission type. The quantum dot has a core-shell structure. The shell thickness is 1.3 nm to 2.5 nm. A thin film transistor connected to the light-emitting element is preferably an n-ch TFT.SELECTED DRAWING: Figure 1 【課題】量子ドットを含む表示装置を提供することを目的とする。【解決手段】本発明は、表示領域を備えた表示装置であって、前記表示領域は、第１電極、前記第１電極と発光層との間の層、前記発光層、前記発光層と第２電極との間の層、及び、前記第２電極が基板上にこの順で積層された発光素子を有し、前記発光層は、量子ドットを含む無機層で形成されており、前記発光素子は、トップエミッション型であり、前記量子ドットは、コアシェル構造であり、シェル厚は、１．３ｎｍ～２．５ｎｍである、ことを特徴とする。本発明では、前記発光素子に接続される薄膜トランジスタが、ｎ－ｃｈ ＴＦＴであることが好ましい。【選択図】図１
