1. A display device comprising:
a first substrate;
data lines disposed on the first substrate and spaced apart from one another;
a first insulating layer disposed over the data lines;
an active layer disposed on the first insulating layer;
a first gate insulating layer disposed over the active layer;
a gate line disposed on the first gate insulating layer and partially overlapping with the data lines;
a second insulating layer disposed over the gate line and the first gate insulating layer;
a conductive pattern disposed on the second insulating layer and totally overlapping with the active layer;
an electrode disposed on the conductive pattern; and
a third insulating layer disposed between the electrode and the conductive pattern,
wherein the conductive pattern does not overlap with the data lines in a direction parallel to an upper surface of the first insulating layer,
wherein the conductive pattern comprises a first surface facing the active layer and a second surface opposite to the first surface, and
wherein the second surface of the conductive pattern comprises a first portion directly contacting the electrode and a second portion directly contacting the third insulating layer.
