  • Publication number: 20230337482
    Abstract: An organic light emitting display device is disclosed that uses a hybrid type thin film transistor. The organic light emitting display device includes a conductive pattern with a higher etch resistance compared to an inorganic thin film in an upper edge of a semiconductor pattern, and is thereby capable of simplifying a manufacturing process of a substrate on which an array of hybrid type thin film transistors each including multiple layers is disposed, and improving the performance of thin film transistors formed on the array substrate. The organic light emitting display device can represent a variety of grayscale images at low grayscales as a driving thin film transistor including an oxide semiconductor pattern is designed to have an increased s-factor value.
