ORGANIC LIGHT EMITTING DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

The present invention relates to an organic light emitting display device capable of preventing light from being projected to an oxide TFT by forming a light shield with source/drain metal, and a manufacturing method of the organic light emitting display device capable of increasing production efficiency by reducing the number of masks. The organic light emitting display device according to an embodiment of the present invention comprises a switching thin film transistor including: a lower gate, a source, and a drain formed on the same layer on a substrate; a first gate insulating film which is formed to cover the lower gate, the source, and the drain; an active formed on the first insulating film; a conductive line which is formed to be in contact with the source and the drain; a second gate insulating film formed on the active; and an upper gate formed on the gate insulating film. The lower gate of the switching thin film transistor is a light shield capable of preventing the light from being projected to the active.
