THIN-FILM TRANSISTOR ARRAY SUBSTRATE, MANUFACTURING METHOD THEREOF, AND ORGANIC LIGHT EMITTING DISPLAY APPARATUS

摘要

For a thin film transistor array substrate capable of reducing the interference of other lines and a capacitor and simplifying manufacturing processes, an organic light emitting display apparatus, and a manufacturing method thereof, the present invention provides a thin film transistor array substrate, an organic light emitting display apparatus including a thin film transistor and a manufacturing method thereof. The thin film transistor array substrate includes a substrate; a thin film transistor which is arranged on the substrate, and includes an active layer, a gate electrode, a source electrode, and a drain electrode; a pixel electrode which is electrically connected to one of the source electrode and the drain electrode; and a capacitor which includes a lower capacitor electrode including the same material as the active layer and is arranged in the same as the active layer, and an upper capacitor electrode which including the same material as the pixel electrode.
