<p><P>PROBLEM TO BE SOLVED: To solve the following problem: in a conventional light-emitting element of a structure in which an organic compound is laminated on an electrode formed of an inorganic material, sufficient luminance cannot be obtained, power consumption is higher, a half-life period of luminance is short, and stability is to be improved. <P>SOLUTION: In the light-emitting device, a lamination structure of a translucent oxide conductive layer containing silicon or silicon oxide is adopted as a hole injection electrode (a positive electrode) in place of a conventional translucent oxide conductive layer of an ITO or the like. Meanwhile, a lamination structure of a translucent oxide conductive layer containing a different content of silicon or silicon oxide is adopted. Preferably, a silicon or silicon oxide concentration in a conductive layer on a side to be connected with a TFT shall be 1-6 atom% and a silicon or silicon oxide concentration on a side of a layer containing an organic compound shall be 7-15 atom%. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
