METHOD OF MANUFACTURING AN ORGANIC LIGHT EMITTING DISPLAY DEVICE

摘要

A organic light emitting display device includes a thin film transistor (TFT) having a gate electrode (230), a source electrode (250) and a drain electrode (250) which are insulated from the gate electrode (230), and a semiconductor layer (210) which is insulated from the gate electrode (230) and which contacts each of the source electrode (250) and the drain electrode (250); and a pixel electrode (310) electrically connected to one of the source electrode (250) and the drain electrode (250). The gate electrode (230) is made up of a first conductive layer (231) and a second conductive layer (232) on the first conductive layer (231), and the pixel electrode (310) is formed of the same material as the first conductive layer (231) of the gate electrode (230) and situated on the same layer (110) as the first conductive layer (231) of the gate electrode (230).
