1. A method of manufacturing a display panel, the method comprising:
sequentially forming a first layer and a second layer on a carrier substrate such that bottom surfaces of the first layer and the second layer face the carrier substrate;
forming a panel substrate including a first base layer on a top surface of the second layer such that a bottom surface of the first base layer faces the second layer;
forming a display layer on the panel substrate; and
separating the panel substrate from the second layer,
wherein:
the separating of the panel substrate includes detaching the bottom surface of the first base layer from the top surface of the second layer; and
a bonding force between the second layer and the first base layer in a contact state is less than a bonding force between the first layer and the first base layer in a contact state.
