A mask for deposition for forming a pattern on a transparent substrate according to the present invention includes a mask member having a mask alignment mark penetratedly formed so as to be aligned with a substrate alignment mark formed on the transparent substrate; and an unevenness region formed on one surface of the mask member so as to be adjacent to the mask alignment mark and having protrusions and depressions on a surface thereof. In accordance with embodiments of the present invention, it is possible to prevent the alignment error of the mask from occurring by increasing the recognition rate of the align marks formed on the substrate and the mask. As a result, it is possible to reduce the manufacturing costs by reducing the defective rate of the organic light emitting diode (OLED) display device.
