Abstract:
A method for manufacturing an organic EL device on a transparent substrate including a display region and a non-display region, the display region having pixel regions, comprising:forming a first electrode, a first lead and a second lead on the transparent substrate; depositing a photoresist layer over the entire transparent substrate covering the first electrode; aligning a first mask on a front side of the transparent substrate; aligning a second mask on a back side of the transparent substrate; forming an insulating layer and a plurality of partition walls, the insulating layers being formed on the display region other than the pixel regions of the display; forming an EL light emitting layer on the pixel regions; and forming a second electrode on the EL light-emitting layer, wherein the first lead and the second lead are formed on the non-display region, and wherein a ratio between a height of the insulating layer and a height of the partition walls is 1:4.
