Abstract

Disclosed is a method of manufacturing an organic light emitting display device. The method include forming a driving thin film transistor and passivation layer on a substrate, forming a bank layer at a boundary portion between adjacent sub-pixels, on the passivation layer, laminating a first photoresist film on the bank layer, forming a first photoresist pattern by irradiating IR light on the first photoresist film in an area except a first sub-pixel, depositing a first organic emission layer in the first sub-pixel area exposed by the first photoresist pattern, removing the first photoresist pattern, laminating a second photoresist film on the bank layer, forming a second photoresist pattern by irradiating IR light on the second photoresist film in an area except a second sub-pixel, depositing a second organic emission layer in the second sub-pixel area exposed by the second photoresist pattern, and removing the second photoresist pattern.
