ORGANIC LIGHT EMITTING DISPLAY DEVICE

An organic light emitting display device is disclosed. In particular, a driving TFT and a first switching TFT disposed in a sub-pixel of a display area each include an oxide semiconductor pattern as an active layer, and the driving TFT includes a shielding pattern capable of shielding an electric field between the oxide semiconductor pattern and a gate electrode, this makes it possible to realize a driving TFT that can exhibit rich gradation even at low gradation levels. 公开了一种有机发光显示装置。特别地，设置在显示区域的子像素中的驱动TFT和第一开关TFT各自包括作为有源层的氧化物半导体图案，并且驱动TFT包括能够屏蔽氧化物半导体图案与栅电极之间的电场的屏蔽图案，由此使得可以实现即使在低灰度级下也能够表现出丰富灰度的驱动TFT。
