摘要： A donor substrate includes a base substrate; a light reflection layer on the base substrate and partially overlapping the base substrate; a light-to-heat conversion layer on the base substrate, and including a combination layer including an insulating material and a first metal material; and a transfer layer on the light-to-heat conversion layer. A ratio of the first metal material in the combination layer to the insulating material in the combination layer increases as a distance from the base substrate increases along a thickness direction of the light-to-heat conversion layer.
