Abstract: A thin film transistor substrate includes: a polymer substrate, an oxide transparent electrode layer (TCO) formed on the polymer substrate, a barrier layer formed on the oxide transparent electrode layer, and a semiconductor layer formed on the barrier layer, in which the semiconductor layer is polysilicon. The polysilicon thin film transistor provides an oxide transparent electrode layer (TCO) which absorbs heat energy and light generated during a process of manufacturing the polysilicon thin film transistor to prevent a damage of the substrate using a polymer material.

Abstract: A touch sensor includes a plurality of touch electrodes on a touch area to sense touch, each of the touch electrodes having a plurality of branch electrodes parallel to each other in a first direction, and connection lines on the touch area and connected to the touch electrodes, the connection lines extending in the first direction in parallel to the branch electrodes, wherein a width of the connection line and a width of the branch electrode are equal to each other.

Abstract: An organic light-emitting display apparatus and a fabrication method thereof are disclosed. The organic light-emitting display apparatus may include, for example, a flexible substrate, a plurality of barrier layers formed on the flexible substrate, a thin film transistor (TFT) formed on the barrier layers, the TFT including a semiconductor active layer, and at least one thermal emission layer formed between the barrier layers, an organic light-emitting device (OLED) electrically connected to the TFT, formed on the barrier layers, and an encapsulation portion encapsulating the OLED.
