发明名称 LIGHT EMITTING ELEMENT, DISPLAY DEVICE AND ELECTRONIC APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide: a light emitting element that includes a plurality of layers having a light emitting function between a cathode and an anode, capable of selectively or dominantly emitting light from a desired layer among the plurality of layers having a light emitting function; a display device; and an electronic apparatus. <P>SOLUTION: A light emitting element 1R includes: a blue light emitting functional layer 5B provided between an anode 3R and a cathode 8; and a red light emitting functional layer 5R provided between the anode 3R and the blue light emitting functional layer 5B. The light emitting element 1R further includes a carrier selection layer 46 comprising a laminate formed by laminating a hole transport layer 43 and a first electron injection layer 61, in this order, from the side of the blue light emitting functional layer 5B between the blue light emitting functional layer 5B and the red light emitting functional layer 5R. <P>COPYRIGHT: (C)2012,JPO&INPIT
