量子点发光器件及其制备方法及液晶显示装置
摘要：
本发明提供一种量子点发光器件及其制备方法及液晶显示装置。量子点发光器件包括基板及设置在基板同侧的阳极、空穴传输层、发光层、电子传输层及阴极，阳极与阴极相对且间隔设置，空穴传输层、发光层及电子传输层夹设在阳极与阴极之间，且空穴传输层的一面与阳极相连，发光层及电子传输层依次层叠设置在空穴传输层远离阳极的一面，且电子传输层远离发光层的一面与阴极相连，阳极用于提供空穴，空穴传输层用于将空穴传输至发光层，阴极用于提供电子，电子传输层用于将电子传输至发光层，空穴和电子在发光层中复合以发光，其中，发光层包括量子点发光材料及有机小分子发光材料，有机小分子发光材料填充量子点发光材料之间的间隙。
摘要（英）：

A quantum dot light emitting device includes a base plate and an anode, a hole transportation layer, a light emissive layer, an electron transportation layer, and a cathode arranged on the same side of the base plate. The anode and the cathode are opposite to and spaced from each other and receive the hole transportation layer, the light emissive layer, and the electron transportation layer to be interposed therebetween. The hole transportation layer is connected to the anode. The light emissive layer and the electron transportation layer are sequentially stacked on the hole transportation layer that is distant from the anode. The electron transportation layer is connected to the cathode. The light emissive layer includes a quantum dot light emitting material and a small-molecule organic light emitting material, which is filled in gaps present in the quantum dot light emitting material.
