发明名称 Active device array substrate and manufacturing method thereof
摘要 A method for manufacturing an active device array substrate includes providing a flexible substrate having a transistor region and a transparent region; forming a gate electrode on the transistor region; sequentially forming a dielectric layer and a semiconductor layer to cover the gate electrode and the flexible substrate; removing a part of the semiconductor layer to form a channel layer above the gate electrode and removing a thickness of the dielectric layer disposed on the transparent region, such that a portion of the dielectric layer on the gate electrode has a first thickness, and another portion of the dielectric layer on the transparent region has a second thickness less than the first thickness; respectively forming a source electrode and a drain electrode on opposite sides of the channel layer; and forming a pixel electrode electrically connected to the drain electrode.
