Abstract:
1. A method for preventing a short circuit between metal wires in an organic light emitting diode display device, comprising: forming an inorganic layer on a substrate; forming a metal layer on the inorganic layer, the metal layer comprising at least two metal wires; forming an organic layer on the two metal wires of the metal layer; forming an indium tin oxide layer on the organic layer; coating a photoresist layer; performing an exposure step to the photoresist layer by utilizing a photo mask, the photo mask having a transparent area corresponding to a position between the two metal wires, an opaque material disposed in the transparent area, wherein a width of the transparent area of the photo mask is a resolution of the photo mask, and a width of the opaque material is less than the width of the transparent area of the photo mask; performing a development step to the photoresist layer; and performing an etching step to remove a part of the indium tin oxide layer and a part of the organic layer.
