Abstract

An organic light-emitting display device, a method of manufacturing the same, and a donor substrate and a donor substrate set used to manufacture the organic light-emitting display device. According to an aspect of the present invention, there is provided an organic light-emitting display device comprising a substrate which comprises a green region and a red region, a plurality of first electrodes which are formed on the green region and the red region of the substrate, respectively, a plurality of light-emitting layers which are formed on the first electrodes and comprise a green light-emitting layer formed on the green region and a red light-emitting layer formed on the red region, and a second electrode which is formed on the light-emitting layers, wherein the green light-emitting layer comprises a first light-emitting layer which comprises a first host material and a first dopant material and a first buffer layer which is formed on the first light-emitting layer and comprises the first host material, and the red light-emitting layer comprises a second light-emitting layer which comprises a second host material and a second dopant material and a second buffer layer which is formed on the second light-emitting layer and comprises the first host material.

Claims (11)

1. A donor substrate comprising:

a base film comprising a first region and a second region;

a buffer layer on the base film, the buffer layer comprising a first host material;

a transfer layer, having a first thickness, for forming a first light-emitting layer, the transfer layer for forming the first light-emitting layer being on the first region of the buffer layer and comprising the first host material and a first dopant material; and

a transfer layer, having a second thickness which is different from the first thickness, for forming a second light-emitting layer, the transfer layer for forming the second light-emitting layer being on the second region of the buffer layer and comprising a second host material and a second dopant material,

wherein the transfer layer for forming the first light-emitting layer and the transfer layer for forming the second light-emitting layer are separated from each other on the base film.

2. The donor substrate of claim 1 , further comprising:

a transfer layer for forming a first auxiliary layer, the transfer layer for forming the first auxiliary layer being on the transfer layer for forming the first light-emitting layer; and

a transfer layer for forming a second auxiliary layer, the transfer layer for forming the second auxiliary layer being on the transfer layer for forming the second light-emitting layer.

3. The donor substrate of claim 1 , further comprising a light-to-heat conversion layer which is formed between the base film and the buffer layer.

4. The donor substrate of claim 3 , further comprising an intermediate layer between the light-to-heat conversion layer and the buffer layer.
