Light emitting device and display unit using it

本发明提供一种发光器件以及使用它的显示装置，其中，该发光器件可通过减少薄膜厚度分布来防止产生不规则的色彩。在驱动基板上依次层叠第一电极，包含发光层的有机层，包含半透明电极的第二电极。发光层包含红光发光层、绿光发光层和蓝光发光层。通过转印原溶液并接着去除溶剂来形成发光层。第一电极的第一端和第二电极的第二端之间的光程满足：(2L)/λ+Φ/(2π)＝m，其中，λ代表要提取的光的光谱的峰值波长，Φ代表在第一端和第二端之间生成的反射光的相移，而m代表一整数。 The invention provides a light emitting device which can prevent irregular color by reducing film thickness distribution and a display unit using it. A first electrode (13), an organic layer (14) including a light emitting layer (14B), a second electrode (15) including a semi-transparent electrode are sequentially layered on a driving substrate (10). The light emitting layer has a red light emitting layer (14BR), a green light emitting layer (14BG), and a blue light emitting layer (14BB). The light emitting layer is formed by transferring a raw solution by every color, and then removing the solvent. An optical distance (L) between a first end of the first electrode and a second end of the second electrode satisfies (2L)/ » + ¦/(2À)=m. » represents a peak wavelength of a spectrum of a light desired to be extracted, ¦ represents a phase shift of reflected lights generated in the first end and the second end, and m represents an integer.
