Patent ID: 8797494

Claim:
A method for manufacturing a display device comprising: providing a first substrate and forming an active area and a driving circuit on the first substrate, wherein the driving circuit has a first side facing the active area and a second side opposite to the first side; providing a second substrate and forming a mask layer and a sealing material on the second substrate; assembling the first substrate and the second substrate, wherein the sealing material is between the second substrate and the first substrate and located beside the second side of the driving circuit, and a projection of the mask layer on the first substrate at least overlaps the driving circuit from the second side to the first side; and using a laser beam to irradiate the sealing material, wherein part of the laser beam passes through the second substrate first and then irradiates on the sealing material, and another part of the laser beam, which exceeds an area of the sealing material, irradiates on the mask layer, so as to prevent the laser beam from irradiating on the driving circuit.
