Claim:
A thin-film layer structure comprising: a substrate; a plurality of banks with a substantially identical height formed on the substrate, the banks cooperatively defining a plurality of spaces therein, the spaces being arranged in rows and columns, the spaces in each row having different underside areas aligned in the substrate, the banks made of photo-resist material; and a plurality of thin-film layers received in the spaces being made of ink, the thin-film layer in each space having a same thickness, and the thin-film layers received in the spaces in each row having a same material in one color and an irregular thickness distribution, and materials of the thin-film layers received in the spaces in every three rows being different from each other, the thin-film layers received in the spaces of each row in a same row having the irregular thickness distribution, wherein the thin-film layer in the same row is being deposited by a same nozzle of an ink jet head upon performing a relative movement along the same row between the ink jet head and the substrate.
