Abstract:
1. A semiconductor device comprising: a first substrate having a first thin film transistor including an organic semiconductor for a channel portion adjacent to a region in which a scan line and a data line intersect with each other with an insulating layer interposed therebetween; a second substrate having a counter electrode; and a third substrate having a second thin film transistor including a crystalline semiconductor for a channel portion, wherein the crystalline semiconductor comprises a grain boundary which extends along a flow of electrons or holes in the second thin film transistor; wherein the first substrate and the second substrate are attached to each other so that the first substrate is exposed; wherein the third substrate is attached to an exposed region over the first substrate; wherein a first region for forming the second thin film transistor and a second region for forming an input terminal and an output terminal are formed over the third substrate; and wherein the short side length of the third substrate is in the range of 1 to 6 mm, and the short side length of the first region is in the range of 0.5 to 1 mm.
