Abstract:
1. A method for manufacturing an organic electroluminescence display comprising a pixel of an electroluminescence element of a first color, a pixel of an electroluminescence element of a second color and a pixel of an electroluminescence element of a third color, the method comprising: preparing a substrate; forming a first electrode on the substrate; forming a partition wall on the substrate so that the pixel is sectioned; forming a hole transport layer on the first electrode; forming an organic light emitting layer of the first color in the pixel of the electroluminescence element of the first color; forming an organic light emitting layer of the second color in the pixel of the electroluminescence element of the second color; forming an organic light emitting layer of the third color in the pixel of the electroluminescence element of the third color, the organic light emitting layer of the first color, the organic light emitting layer of the second color and the organic light emitting layer of the third color having different life-time in light emitting, the organic light emitting layer of the first color, the organic light emitting layer of the second color and the organic light emitting layer of the third color being not stacked on each other and being separated by the partition wall, and forming a second electrode above the organic light emitting layer of the first color, the organic light emitting layer of the second color and the organic light emitting layer of the third color, wherein the organic light emitting layer having a longer life-time is formed earlier.
