发光装置和平板显示设备
摘要：
提供发光装置和平板显示设备。发光装置包括：第一电极，分别在第一子像素、第二子像素和第三子像素上；第二电极，面向第一电极；第一发射层，在第一子像素上以发射第一颜色光；第二发射层，在第二子像素上以发射第二颜色光；第一层，与第一子像素、第二子像素和第三子像素集成；第一辅助层，在第一层与第一发射层之间；第一中间层，在第一辅助层与第一发射层之间。第一中间层的最高占据分子轨道(HOMO)能级的绝对值比第一辅助层的HOMO能级的绝对值大，并比第一发射层的HOMO能级的绝对值小。第一中间层的最低未占据分子轨道(LOMO)能级的绝对值比第一辅助层的LUMO能级的绝对值大，并比第一发射层的LUMO能级的绝对值小。
摘要（英）：

A light-emitting device and a panel display device are provided. The light-emitting device includes: first electrodes positioned on a first sub-pixel, a second sub-pixel, and a third sub-pixel, respectively; a second electrode facing first electrodes; a first emission layer on the first sub-pixel to emit a first color light; a second emission layer on the second sub-pixel to emit a second color light; a first layer integrated with the first sub-pixel, the second sub-pixel, and the third sub-pixel; a first auxiliary layer between the first layer and the first emission layer; and a first interlayer between the first auxiliary layer and the first emission layer. The absolute value of the highest occupied molecular orbital (HOMO) energy level of the first interlayer is greater than the absolute value of the HOMO energy level of the first auxiliary layer, and is smaller than the absolute value of the HOMO energy level of the first emission layer. The absolute value of the lowest unoccupiedmolecular orbital (LUMO) energy level of the first interlayer is greater than that of a LUMO energy level of the first auxiliary layer, and is smaller than the absolute value of the LUMO energy levelof the first emission layer.
