HYBRID THIN FILM TRANSISTOR AND ORGANIC LIGHT EMITTING DISPLAY DEVICE USING THE SAME

Different types of thin film transistors are disposed on the same flexible substrate and an organic light emitting display using the same includes a display area and a non-display area; a first bufferlayer over an entire surface of the flexible substrate; a driving transistor on the buffer layer in the display area, the driving transistor including a polycrystalline silicon (LIPS) layer, a firstgate electrode, a first source electrode, and a first drain electrode; a capacitor electrode on the first source electrode of the driving transistor and forming a storage capacitor together with the first source electrode; a switching transistor in the display area to be spaced apart from the driving transistor; and a dummy electrode on the switching transistor, the dummy electrode formed of the same material as the capacitor electrode, and disposed on the same plane as the capacitor. 不同类型的薄膜晶体管设置在同柔性基板上，使用其的有机发光显示装置包括：具有显示区域和非显示区域的柔性基板；位于柔性基板的整个表面上方的第缓冲层；位于显示区域中且位于第缓冲层上的驱动晶体管，驱动晶体管包括多晶硅(LTPS)层、第栅极、第源极和第漏极；电容器电极，电容器电极位
