Claim:
1. An optical patterning mask, comprising: a base substrate; a reflective layer disposed on the base substrate and including an opening; a thermal insulation layer disposed on the reflective layer to cover the opening; a light absorption layer disposed on the thermal insulation layer; a tapered layer arranged between the thermal insulation layer and the light absorption layer; a protection layer disposed on the light absorption layer to overlap the opening; a bank layer disposed on the light absorption layer to expose the protection layer; and a transfer layer disposed on the protection layer and the bank layer, wherein the protection layer is thinner than the bank layer, wherein the transfer layer comprises a transfer inclination portion having an inclination in a portion that overlaps an edge of the opening, and wherein the tapered layer includes a tapered inclination portion formed to expose a portion of the thermal insulation layer overlapping the opening.
