Abstract
Official abstract text for this publication.
A display device and a method for fabricating the same. The display device includes a substrate including a circuit layer and a first pad unit; an auxiliary substrate disposed below the substrate and comprising a driving circuit and a second pad unit; a light-emitting unit disposed on the circuit layer; and a connection electrode in contact with a side surface of the substrate and electrically connecting the first pad unit with the second pad unit. The method includes forming a circuit layer and a first pad unit on a first surface of a substrate; forming a driving circuit and a second pad unit on a fourth surface of an auxiliary substrate; and attaching a second surface of the substrate opposite the first surface to a third surface of the auxiliary substrate opposite the fourth surface.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of fabricating a display device, the method comprising: forming a circuit layer and a first pad unit on a first surface of a substrate; forming a driving circuit and a second pad unit on a fourth surface of an auxiliary substrate; and attaching a second surface the substrate opposite the first surface to a third surface of the auxiliary substrate opposite the fourth surface. 2 . The method of claim 1 , further comprising a connection electrode that connects the first pad unit with the second pad unit. 3 . The method of claim 2 , further comprising forming a light-emitting unit on the circuit layer. 4 . The method of claim 3 , wherein the auxiliary substrate is made of a glass material. 5 . The method of claim 4 , wherein the light-emitting unit comprises a light-emitting diode. 6 . The method of claim 5 , wherein the light-emitting diode comprises a first semiconductor layer, a second semiconductor layer, and an intermediate layer between the first semiconductor layer and the second semiconductor layer; and a first electrode pad is formed on the first semiconductor layer and a second electrode pad is formed on the second semiconductor layer.
