Abstract
A transistor includes an active layer on a substrate, a first metal pattern and a second metal pattern disposed beneath the active layer and spaced apart from each other by a first distance in a first direction while overlapping with the active layer, a gate electrode disposed on the active layer while overlapping with the active layer and having a width along the first direction that is greater than the first distance, a gate insulating layer between the active layer and the gate electrode, a first source-drain electrode connected to the first metal pattern and a second source-drain electrode connected to the second metal pattern and spaced apart from the first source-drain electrode.
