Patent ID: 7772050

Claim:
A method for manufacturing a flat panel display, employed on a display substrate comprising a metal layer, a dielectric layer and an insulating layer disposed between the metal layer and the dielectric layer and comprising the following steps: forming a first photoresist layer on the display substrate; performing a first exposure process on the first photoresist layer by a mask to define a first region, a second region and a third region on the display substrate, wherein the mask comprises a substrate, a first material layer and a second material layer, the first material layer and the second material layer are disposed on the substrate to define a fourth region, a fifth region and a sixth region, the fourth region corresponds to the first region, the fifth region corresponds to the second region, and the sixth region corresponds to the third region; removing part of the first photoresist layer in the first region; etching part of the dielectric layer in the first region; removing the first photoresist layer; forming an electrode layer on the display substrate; forming a second photoresist layer on the electrode layer; performing a second exposure process on the second photoresist layer by the mask; removing part of the second photoresist layer in the third region; etching part of the electrode layer in the third region; and removing the remained second photoresist layer.
