Light emitting device

Abstract

A light emitting device includes a first light emitting element, a second light emitting element disposed adjacent to the first light emitting element, a first color conversion element disposed on the first light emitting element, and a second color conversion element disposed on the second light emitting element. A thickness of the first color conversion element is different from a thickness of the second color conversion element.

What is claimed is: 
     
         1 . A light emitting device, comprising:
 a first light emitting element;   a second light emitting element disposed adjacent to the first light emitting element;   a first color conversion element disposed on the first light emitting element; and   a second color conversion element disposed on the second light emitting element;   
       wherein a thickness of the first color conversion element is different from a thickness of the second color conversion element. 
     
     
         2 . The light emitting device of  claim 1 , wherein the first light emitting element comprises a portion of a light emitting layer, the second light emitting element comprises another portion of the light emitting layer, and the light emitting layer is a continuous layer across the first light emitting element and the second light emitting element. 
     
     
         3 . The light emitting device of  claim 2 , further comprising a pixel defining layer, wherein the light emitting layer is in contact with a top surface of the pixel defining layer. 
     
     
         4 . The light emitting device of  claim 3 , wherein the first light emitting element comprises a first electrode and a second electrode, wherein the portion of the light emitting layer is disposed between the first electrode and the second electrode, and the first electrode and the second electrode overlap with the pixel defining layer. 
     
     
         5 . The light emitting device of  claim 1 , wherein a surface of at least one of the first color conversion element is curved. 
     
     
         6 . The light emitting device of  claim 1 , further comprising:
 an insulating layer disposed between the first light emitting element and the first color conversion element.   
     
     
         7 . The light emitting device of  claim 1 , further comprising:
 a first transistor electrically connected to the first light emitting element, wherein the first color conversion element overlaps with the first transistor.   
     
     
         8 . The light emitting device of  claim 7 , wherein the first transistor comprises a semiconductor layer, and the first color conversion element overlaps with the semiconductor layer. 
     
     
         9 . The light emitting device of  claim 8 , wherein the semiconductor layer comprises amorphous silicon, polysilicon, or indium gallium zinc oxide (IGZO). 
     
     
         10 . The light emitting device of  claim 1 , wherein at least one of the first color conversion element or the second color conversion element comprises a color filter.
