Abstract
Official abstract text for this publication.
An organic light emitting display device includes a substrate including a plurality of pixels defined thereon; a first electrode disposed at each pixel; a bank exposing the first electrode of each pixel; a spacer including, sequentially on the bank, a first layer of a first negative photoreactive acryl and a second layer of a second negative photoreactive acryl having a greater photoreactivity than a photoreactivity of the first negative photoreactive acryl, wherein the first layer has a negative taper and the second layer has a positive taper; an organic layer on the bank and the first electrode, the organic layer including an organic light emitting layer; and a second electrode on the bank, the spacer, and the organic layer.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of manufacturing an organic light emitting display device, comprising: providing a substrate including a plurality of pixels defined thereon; forming a first electrode at each pixel; forming a bank exposing the first electrode of each pixel; sequentially depositing, on the bank, a first layer of a first negative photoreactive acryl and a second layer of a second negative photoreactive acryl having a greater photoreactivity than a photoreactivity of the first negative photoreactive acryl; forming a spacer including the first layer having a negative taper and the second layer having a positive taper by applying a mask over the second layer, the mask having an open portion to open a predetermined portion of the bank; forming an organic layer including an organic light emitting layer on the bank and the first electrode; and forming a second electrode on the bank, the spacer, and the organic layer. 2 . The method according to claim 1 , wherein the organic layer includes a plurality of organic light emitting layers that are respectively disposed at each pixel to be spaced from each other with respective spacers therebetween. 3 . The method according to claim 1 , wherein the pixels are arranged in a diagonal direction on the substrate. 4 . The method according to claim 3 , wherein each pixel has a rhombus shape, and wherein the pixels have sizes that differ according to colors of the respective organic light emitting layers.
