FLAT DISPLAY AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a flat display for less degradation in characteristics of an organic thin film transistor. SOLUTION: The manufacturing method of a flat display includes a step for providing an insulating substrate; a step to form a source electrode and a drain electrode that are provided apart to define a channel region on the insulating substrate; a step for forming a first protective layer on the source electrode and the drain electrode; a step for forming a metal layer in which an opening corresponding to the channel region is provided on the first protective layer; a step for forming a placement hole for exposing the channel region on the first protective layer through the opening with the metal layer as a mask, a step for forming an organic semiconductor layer and a second protective layer sequentially inside the placement hole and on the metal layer; and a step for removing the second protective layer and the organic semiconductor layer other than the placement hole and the metal layer.
