Patent ID: 8048728

Claim:
A method for manufacturing a display device, comprising the steps of: implanting an ion into a first substrate to form a first single-crystalline semiconductor layer; cutting the first single-crystalline semiconductor layer into a plurality of single-crystalline semiconductor layers each having an area including one panel; bonding the plurality of single-crystalline semiconductor layers to a second substrate with an insulating layer interposed therebetween; exposing second and third single-crystalline semiconductor layers each having the area including one panel selected from the plurality of single-crystalline semiconductor layers at a time; and patterning the second and third single-crystalline semiconductor layers to form a first display portion over the second substrate using the patterned second single-crystalline semiconductor layer and to form a second display portion over the second substrate using the patterned third single-crystalline semiconductor layer, wherein the step of patterning is performed after the step of bonding.
