Abstract
A liquid crystal display device includes first thin film transistor with a first polysilicon active layer in which a first channel area has first grain boundaries, wherein the first thin film transistor has a first channel direction different from a first grain boundary direction of the first grain boundaries, and a second thin film transistor with a second polysilicon active layer in which a second channel area has second grain boundaries, wherein the second thin film transistor has a second channel direction parallel to a second grain boundary direction of the second grain boundaries, wherein the first and second transistors have a substantially same electrical characteristic.
