An apparatus for manufacturing a display panel includes an arriving part in which an unfinished display panel is disposed. The apparatus has at least one light transmitting part, a mold which is positioned on the arriving part and which includes at least one alignment key and a pattern forming part, a mold driver which drives the mold, and an alignment sensor which is positioned under the arriving part and which determines whether the display panel and the mold are erroneously aligned through the light transmitting part. Therefore, it is possible to efficiently and accurately pattern a specific material onto the display panel through an imprint lithography process using a pressing mold.
