Abstract: Provided is a configuration for a semiconductor layer and a line for reducing the segment length of the semiconductor layer with respect to the bending direction of the flexible substrate. Such a configuration reduces the probability of cracks occurring in the semiconductor layer of the thin-film transistor, thereby improving the stability and durability of the thin-film transistor employed in a curved or a flexible display device. The configuration includes a thin-film transistor (TF) on the flexible substrate. The TFT includes the semiconductor layer extending obliquely with respect to the direction of the line.

Abstract: An organic light emitting display device is discussed. The organic light emitting display device according to an embodiment includes a base substrate, a buffer layer disposed on the base substrate, and a thin film transistor disposed on the buffer layer. The organic light emitting display device further includes an organic light emitting diode connected to the thin film transistor and disposed on the thin film transistor. The thin film transistor includes a gate electrode, a source electrode, and a drain electrode. At least one of the gate, source, and drain electrodes of the thin film transistor includes a semi-transmissive metal layer, a transparent metal layer, and a reflective metal layer to improve outdoor visibility of a display panel by reducing reflectance of the electrodes even though a polarizer is removed.
