Display unit

Abstract

A display unit that secures favorable display performance and has a simple structure is provided. The display unit includes a multilayer structure in which an organic light emitting device group respectively having a plurality of organic light emitting devices that emits cyan light and a plurality of organic light emitting devices that emits magenta light and a color filter group having a plurality of blue filters that transmit blue light and a plurality of yellow filters that transmit yellow light are sequentially layered. In the display unit, the cyan light and the magenta light entering from the organic light emitting device group to the color filter group is converted to blue light by the blue filter, and is respectively converted to green light and red light by the yellow filter. Therefore, compared to a case that the organic light emitting device group emits white light, color separation is more facilitated.

1 . A display unit comprising:
 a multilayer structure in which a light emitting device group that respectively has a plurality of cyan organic light emitting devices emitting cyan light and a plurality of magenta organic light emitting devices emitting magenta light and a color filter group that has a plurality of blue filters transmitting blue light and a plurality of yellow filters transmitting yellow light are sequentially layered over a substrate.   
     
     
         2 . The display unit according to  claim 1 ,
 wherein the plurality of yellow filters are arranged so that the cyan light from the cyan organic light emitting device enters part of the plurality of yellow filters and the magenta light from the magenta organic light emitting device enters the other part of the plurality of yellow filters, and   wherein the plurality of blue filters are arranged so that at least one of the cyan light from the cyan organic light emitting device and the magenta light from the magenta organic light emitting device enters the plurality of blue filters.   
     
     
         3 . The display unit according to  claim 1 , wherein both the cyan organic light emitting device and the magenta organic light emitting device include a first light emitting unit, a charge generation layer, and a second light emitting unit. 
     
     
         4 . The display unit according to  claim 3 , wherein the charge generation layer injects electrons into the first light emitting unit and injects holes into the second light emitting unit.
