Liquid Crystal Display Device, Electronic Device Having the Same, and Manufacturing Method of the Same

A semiconductor device comprising:

• a first substrate having a first thin film transistor including an amorphous 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,
• 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, and
• wherein the pitch of either or both of the input terminal and the output terminal is the same as that of either the scan line or the data line.
