Abstract

An organic light-emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes a first substrate, an insulating layer disposed over the first substrate and including a first inclined portion and a first electrode disposed over the insulating layer. The OLED display also includes a light-emitting element layer disposed over the first electrode, a second electrode disposed over the light-emitting element layer and a color conversion layer and a transmissive layer disposed over the second electrode. The first electrode includes a second inclined portion disposed over and inclined along the first inclined portion of the insulating layer.

Claims

exact text as granted — not AI-modified
1 - 30 . (canceled) 
     
     
         31 . An OLED display comprising:
 a first substrate;   an insulating layer disposed on the first substrate;   a first electrode disposed on the insulating layer;   a pixel defining layer disposed on the insulating layer and having an opening overlapping the first electrode;   a light emission layer disposed on the first electrode and the pixel defining layer; and   a color conversion layer and a transmissive layer disposed over the light emission layer,   wherein the pixel defining layer includes an inclined portion and the light emission layer includes an inclined portion.   
     
     
         32 . The OLED display of  claim 31 , wherein the color conversion layer and the transmissive layer are respectively disposed between portions of the pixel defining layer. 
     
     
         33 . The OLED display of  claim 31 , wherein the color conversion layer includes a red color conversion media layer and a green color conversion media layer, and wherein the color conversion layer further includes a light blocking member disposed between the red and green color conversion media layers, between the red color conversion media layer and the transmissive layer, and between the green color conversion media layer and the transmissive layer. 
     
     
         34 . The OLED display of  claim 33 , wherein the light emission layer includes a plurality of blue emission layers that respectively correspond to the red and green color conversion media layers and the transmissive layer. 
     
     
         35 . The OLED display of  claim 33 , wherein the red and green color conversion media layers respectively include at least one of a quantum dot and a phosphor, and wherein the transmissive layer does not include the quantum dot and the phosphor. 
     
     
         36 . The OLED display of  claim 33 , wherein at least one of the red and green color conversion media layers and the transmissive layer includes a plurality of scatterers. 
     
     
         37 . The OLED display of  claim 31 , further comprising:
 a second electrode disposed on the light emission layer; and   a capping layer disposed between the second electrode and the color conversion layer and between the second electrode and the transmissive layer.   
     
     
         38 . The OLED display of  claim 31 , further comprising a second substrate disposed over the color conversion layer and the transmissive layer. 
     
     
         39 . The OLED display of  claim 31 , wherein the light emission layer includes a blue emission layer that has a tandem structure. 
     
     
         40 . The OLED display of  claim 31 , wherein the inclined portion of the pixel defining layer is a side portion of the opening. 
     
     
         41 . The OLED display of  claim 31 , wherein the inclined portion of the pixel defining layer overlaps the inclined portion of the light emission layer.
