Abstract:
An embodiment provides a display device manufacturing method comprising the steps of: preparing a substrate having a plurality of semiconductor chips arranged thereon (S1); bonding at least one first semiconductor chip of the plurality of semiconductor chips to a transfer member (S2); irradiating laser light to the first semiconductor chip to separate the first semiconductor chip from the substrate (S3); disposing the first semiconductor chip on a panel substrate of a display device by means of the transfer member (S4); and irradiating light to the transfer member to separate the first semiconductor chip from the transfer member (S5), wherein the transfer member comprises: a transfer layer and a bonding layer disposed on one surface of the transfer layer; the bonding layer comprises at least one bonding protrusion; and the first semiconductor chip is bonded to the bonding protrusion in step S2.
